Empirical testing showed the previous design — grafting a verbose
re-invocation reminder into the payload's `description` field for
started and intermediate messages — was actually making Nova Sonic
*worse*, not better: more spurious re-invocations of the same tool,
not fewer. Plausibly the long, instruction-shaped description text
reads as content the model has to respond to, where a terse status
update reads as ambient state.
Replace the reminder grafting with a caller-supplied `template`
keyword argument on `prepare_message_payload_for_realtime`. When
`None` (the default), the payload is serialized to its canonical
JSON form. When provided, `template.format(tool_call_id=…, status=…,
result=…, description=…)` is applied. The template is honored across
all kinds, so callers route per kind based on which wire channel
they're using.
Nova Sonic now defines its own bracketed plain-text template
(`_ASYNC_TOOL_RESULT_TEXT_TEMPLATE`) and applies it on the
cross-modal user-text channel (intermediate / final). The started
path stays on raw JSON (the formal AWS tool-result channel requires
valid JSON). A code comment at the template constant captures the
empirical finding for the next person — short framing yields much
better behavior, surprising as it sounds.
Tests updated for the new template behavior across all kinds. Also
reverts a stream-tool example sleep-duration tweak (20s → 10s) and
adds a commented-out alternative in the function-calling-openai-async-stream
example for parallel testing.
Reshape the helper module so AsyncToolMessagePayload is the canonical
in-memory form and the on-the-wire JSON is always derived from it
(never stored). This eliminates a drift risk that came with caching
the JSON in raw_content, and it lets prepare_message_payload_for_realtime
edit the payload (graft the re-invocation reminder into 'description')
and then serialize cleanly — which fixes a 'Tool Response parsing error'
from AWS Nova Sonic that was caused by wrapping the JSON with extra
prose.
Other changes:
- Builders construct an AsyncToolMessagePayload internally and convert
via shared private _payload_to_message and _payload_to_json helpers
(centralizing field-omission rules, e.g. no 'result' on 'started').
- prepare_message_payload_for_realtime replaces format_text_for_provider,
dispatching to per-kind helpers. Reminder is now appended after the
canonical description so the model reads the protocol explanation
first and the directive flows from it.
- Final-result payloads are pass-through; the task is done at that
point and re-invocation is no longer a mistake.
- Stream-tool example: lengthen intermediate sleeps 10s → 20s for more
interesting empirical testing.
Add support to AWSNovaSonicLLMService for the new "async tool call"
mechanism activated by `cancel_on_interruption=False`, which includes:
- delivering results asynchronously
- delivering result streams
- cancelling running async tools
Note that the introduction of the new mechanism had actually caused a
regression in AWS Nova Sonic, which previously supported
`cancel_on_interruption=False` with the old mechanism (simply avoiding
discarding tool calls on interruptions).
Support for the other major realtime services (`GeminiLiveLLMService`,
`OpenAIRealtimeLLMService`) will follow in a separate PR — Gemini Live
in particular needs more work before it can support long-running tool
calls reliably.
The pyright job in `format.yaml` previously installed only `--extra
daily --extra tracing`. That was sufficient when most optional-dep-
using files were in the pyright ignore list, but as this PR has
cleared dozens of files, those files now reference symbols from
optional-dep modules (`aiortc.RTCIceServer` via `IceServer`,
`google.genai.types.HttpOptions`, etc.). `reportMissingImports: false`
tolerates the failed imports themselves, but the imported names
become `Unknown` and using them as type expressions trips
`reportInvalidTypeForm` / `reportAttributeAccessIssue` — errors
that aren't gated by that flag.
Switch to `--all-extras --no-extra gstreamer --no-extra local`
(matching the dev setup in README.md), so pyright sees the same
dependency set the code is intended to be type-checked against and
the install-set scales naturally as more files leave the ignore list.
Also reconcile CLAUDE.md's setup command, which only excluded
`gstreamer`. README.md is canonical and additionally excludes
`local` (pyaudio requires `portaudio` native libs that aren't
installed by default on a clean Ubuntu CI runner).
A fourth pass over low-error-count files. Drops 8 files (57 → 49) and
full-pyright errors from 525 → 496. Default pyright stays clean.
Optional access on transport/client receivers (4 files). Same fix
shape as #4359 — a receiver typed `X | None` accessed without a
guard. For "should never happen" cases (caller's lifecycle ensures
the field is non-None when the method runs), used `assert` rather
than silent early-return so an invariant violation surfaces loudly:
- `transports/whatsapp/client.py` (5 errors): `_validate_whatsapp_webhook_request`
was typed `bytes` / `str` but called with `bytes | None` / `str | None`.
Widened the helper signature and pushed the explicit None-check
inside (matching its existing empty-string check). Also handled
`pipecat_connection.get_answer()` returning `None` — would have
crashed at `.get("sdp")` before.
- `transports/websocket/client.py` (5 errors): four are the deprecated
`websockets.WebSocketClientProtocol` alias (same `# pyright: ignore[reportAttributeAccessIssue]`
as the `services/websocket_service.py` fix from earlier in this PR).
The fifth was `async for message in self._websocket` — traced the
call chain and confirmed `_client_task` is created only after
`self._websocket` is assigned and cancelled before it's cleared, so
the field is never None when `_client_task_handler` runs. Used `assert`.
- `services/openai/stt.py` (4 errors): same pattern. `_receive_messages`
is started by `_connect()` only when `self._websocket` is set, and
the reconnect loop in `WebsocketService._receive_task_handler`
re-establishes it before each retry. `assert` at entry. Plus L478/L483:
the `try`/`except ModuleNotFoundError` import-guard makes
`websocket_connect` and `State` `<type> | None`; `__init__` already
raises `ImportError` if either is None, so an `assert` at the
`_connect_websocket` use site is honest. Plus an L538 `Language | str`
cast (same shape as last batch).
- `services/deepgram/flux/base.py` (2 errors): `event = data.get("event")`
flowed into `_handle_turn_resumed(event: str)` as `Any | None`.
Tightened with an `isinstance(event, str)` guard before the
`FluxEventType(event)` lookup. The other error (`average_confidence > min_confidence`
where `min_confidence: float | None`) was a latent crash on missing
confidence data — restored the original `not min_confidence` (which
treats both `None` and `0.0` as "no filter") and added an explicit
drop-on-missing-confidence-data branch.
`gemini_live` Settings/InputParams (vertex). The deprecated `InputParams`
declares `modalities: GeminiModalities | None` and `media_resolution: GeminiMediaResolution | None`,
but their downstream usage at `services/google/gemini_live/llm.py:952,959`
calls `.value` on each — `None` would crash. Rather than touching the
deprecated input model, translate `None` to the canonical defaults
(`GeminiModalities.AUDIO`, `GeminiMediaResolution.UNSPECIFIED`) at the
assignment site in `vertex/llm.py`. Also fixed an unrelated annotation
bug: `_get_credentials` was annotated `-> str` but actually returns
`service_account.Credentials` (used correctly by the caller — only
the annotation was wrong).
`moondream/vision.py` (3 errors). `frame.format` is `str | None` but
`Image.frombytes(mode, ...)` requires `str`; raise instead of crashing
on missing format. The other two errors are pyright thinking the
moondream2-custom `encode_image` and `query` methods are `Tensor`
(rather than callables) — those are provided by the model code via
`trust_remote_code=True` and aren't visible to pyright on the base
`AutoModelForCausalLM` type. Scoped `# pyright: ignore[reportCallIssue]`
on the two call sites.
`transports/base_output.py` (3 errors). Two are `self._mixer.mix(...)`
calls in `with_mixer`, a closure invoked only when `self._mixer` is
truthy at the call site — captured the mixer to a local variable
inside the closure with an `assert`, then used that. Third is the
PIL `frombytes(mode, ...)` shape — `frame.format is None` early-
return guard at the top of `resize_frame` so the main resize logic
reads cleanly.
`elevenlabs/tts.py` (4 errors). The payload-building dict at L1271
was typed `dict[str, str | dict[str, float | bool]]` — an aspirational
shape that matched only the first two assignments. Subsequent code
assigned `list[dict[...]]` (pronunciation locators) and bools, all
violating the annotation. Same pattern at L926 (the WebSocket-init
`msg`). Both widened to `dict[str, Any]`, which is the honest shape
for a JSON request payload and what similar code uses elsewhere.
Files dropped from the ignore list (57 → 49):
services/deepgram/flux/base.py, services/elevenlabs/tts.py,
services/google/gemini_live/vertex/llm.py,
services/moondream/vision.py, services/openai/stt.py,
transports/base_output.py, transports/websocket/client.py,
transports/whatsapp/client.py.
A third pass over low-error-count files in the ignore list. Drops 10
files (67 → 57) and full-pyright errors from 555 → 525. Default
pyright stays clean.
Optional access guards (4 files). The same fix shape as 9e9b1f39e:
a receiver typed `X | None` accessed without a guard, fixed with a
local-var capture or an early return.
- `mistral/stt.py`: `_connection.send_audio` could crash if
`_connect()` swallowed an exception and left `_connection` unset;
drop the audio chunk with a warning instead. `_receive_events`
iterating `_connection.events()` got the same defensive narrowing.
- `deepgram/flux/stt.py`: `_websocket_url` is set in `_connect`
before `_connect_websocket` is called, but pyright doesn't track
that across methods — assert at the use site. `websocket.response`
is `Response | None` in the websockets stubs even though it's
always populated post-handshake; guarded with a fallback.
- `audio/filters/rnnoise_filter.py`: the module-level import sets
`RNNoise` to `None` if `pyrnnoise` isn't installed; raise
`ImportError` explicitly instead of relying on the existing try-
block to catch the `None(...)` call. Also gated `filter()` with
`or self._rnnoise is None` so pyright sees the narrowing.
- `transports/smallwebrtc/request_handler.py`: `get_answer()`
legitimately returns `None`; raise instead of crashing on three
subscript accesses.
`TTSService` `audio-context` API tightening. Mirroring the
`append_to_audio_context` fix from the previous batch:
`remove_audio_context` was typed `str` but is called with `str | None`
from `get_active_audio_context_id()` results. Widened to `str | None`
and the `None` handling lives in the function body (early debug log
+ return) — matching `append_to_audio_context`'s shape.
`audio_context_available` keeps its narrow `str` signature; asking
"is `None` available?" isn't a meaningful question (`_audio_contexts`
is `dict[str, asyncio.Queue]`). The internal call site in
`on_turn_context_completed` narrows `_turn_context_id` explicitly
before passing it. Side effect: deepgram/tts.py's L307 error clears
without local changes.
`deepgram/tts.py` (4 errors → 0): the same `push_error(ErrorFrame(...))`
latent bug we fixed in resembleai earlier in this PR — `push_error`
takes a string; there's a separate `push_error_frame` for frames.
Two sites switched. The Optional `_websocket.response` access is
guarded the same way as deepgram/flux/stt.py. The `remove_audio_context`
error was cleared by the tightening above.
`aws/utils.py` (3 errors → 0): `AWSTranscribePresignedURL` declared
`session_token: str` but the dict source is `str | None` (AWS
supports long-term IAM creds without a session token). Same for
`vocabulary_name`/`vocabulary_filter_name` on `get_request_url`,
which were typed `str = ""` even though the body uses truthy checks
to skip them. Widened to `str | None = None` — matches actual
runtime semantics.
`audio/dtmf/utils.py` (2 errors → 0): `files("...").joinpath(...)`
returns a `Traversable`, but `aiofiles.open` wants a real path. For
regular pip installs this worked in practice (Traversable was a
`Path`), but it would fail for zipped distributions (zipapp,
zipimport) where the resource isn't on disk. Wrapped in
`importlib.resources.as_file(...)` — the canonical bridge that
extracts to a temp file when the resource isn't already on the
filesystem. Validated end-to-end: regular install still reads bytes;
ad-hoc zipapp test confirmed `as_file` extracts the resource and
returns a real Path.
`openai/image.py` (2 errors → 0): the `size` arg to
`images.generate` is `Literal[...] | None` in the SDK but our
settings field is `str | None`. Mirrored the `groq/tts.py`
hint-not-constraint pattern from the previous batch: defined a
module-level `OpenAIImageSize = Literal[...]` alias with a comment
attributing the upstream symbol and documenting the cast contract
(callers can pass any string; invalid values surface as an OpenAI
API error). Also guarded `image.data[0]` (response.data is
`list[Image] | None`).
`processors/frameworks/{langchain,strands_agents}.py` (4 + 4 → 0):
both processors do `messages[-1]["content"]` on a value typed
`LLMStandardMessage | LLMSpecificMessage` (the latter is a dataclass,
not a dict, so `__getitem__` errors). Historically these only
handled plain-text user messages, so the fix is two explicit guards
(skip if the last message isn't a dict; skip if `content` isn't a
string) plus a TODO noting that other shapes (multi-modal content,
provider-specific messages) aren't supported yet. langchain's
`__get_token_value` also got a small fix where `AIMessageChunk.content`
is `str | list[parts]` but the function declares `-> str`; stringify
the list case. strands_agents' surfaced two unrelated narrows: a
`graph_exit_node: str | None` arg gated by an `__init__`-time assert,
and `agent.stream_async` reached only when we're not in graph mode.
Files dropped from the ignore list (67 → 57):
audio/dtmf/utils.py, audio/filters/rnnoise_filter.py,
processors/frameworks/langchain.py,
processors/frameworks/strands_agents.py, services/aws/utils.py,
services/deepgram/flux/stt.py, services/deepgram/tts.py,
services/mistral/stt.py, services/openai/image.py,
transports/smallwebrtc/request_handler.py.
A second pass over the low-error-count files in the ignore list. Drops
10 files (77 → 67) and full-pyright errors from 580 → 555. Default
pyright stays clean.
Three coherent shapes plus a handful of one-offs:
`Language | str | None` → `Language | None` at STT frame boundaries.
`assert_given(self._settings.language)` returns `Language | str | None`
(strips `_NotGiven`, keeps the rest), but `TranscriptionFrame.language`
expects `Language | None`. In practice both `_settings.language` and
SDK-supplied codes resolve to a `Language` enum value, but technically
they could be raw strings — and `Language` is a StrEnum, so downstream
consumers (which mostly compare/serialize as strings) handle either.
Used `cast("Language | None", ...)` at each call site rather than a
runtime-validating helper, so an unrecognised code (e.g. one we
haven't added to the enum yet) still flows through unchanged. Cleared
azure/stt.py, aws/stt.py, gradium/stt.py; mistral/stt.py keeps the
cast at the SDK boundary (storing under `_detected_language: Language
| None`) but stays in the ignore list because of two unrelated
Optional-access errors.
aiobotocore `async with` stub gap. `aioboto3.Session().client(...)`
is an async context manager at runtime but its stubs don't advertise
`__aenter__`/`__aexit__` to pyright. Scoped
`# pyright: ignore[reportGeneralTypeIssues]` on the two affected
sites: aws/agent_core.py and aws/tts.py. aws/tts.py also had a latent
bug on the no-`AudioStream` path: the original code set
`audio_data = None` and then crashed in `resample(...)` and
`len(audio_data)` below; replaced with an early `return` after
logging — matches the convention elsewhere (OpenAI TTS, etc.) of not
recording usage metrics on the error path.
heygen `event_id: str | None` → `str` at transport→client boundary.
Three call sites in transports/heygen/transport.py passed `self._event_id`
(`str | None`) into client methods that take `str`. Added a guard at
each: `agent_speak_end` and `interrupt` only fire when `_event_id` is
set; `write_audio_frame` warn-and-drops when there's no active bot
event rather than sending a malformed message.
`OpenAIResponsesLLMInvocationParams` TypedDict.
`get_llm_invocation_params` always sets both `input` and `tools` in
the same dict literal, but the TypedDict was `total=False` so direct
subscript access (`invocation_params["input"]`) tripped
`reportTypedDictNotRequiredAccess` in services/openai/responses/llm.py.
Marked both keys `Required[...]`; `instructions` stays non-required
since it's only added when a system instruction is present.
Latent bug in heygen/api_interactive_avatar.py: the code accessed
`request_data.voice.voiceId` and `request_data.voice.elevenlabsSettings`,
but those names are Pydantic *aliases*; the actual attribute names
(used for attribute access) are `voice_id` and `elevenlabs_settings`.
Switched to the field names — those camelCase accesses would have
raised AttributeError at runtime if `voice` was set.
Other small fixes:
- assemblyai/stt.py: the deprecated `connection_params=` init path
was reading `formatted_finals` and `word_finalization_max_wait_time`
off `AssemblyAIConnectionParams`, but those fields were never on
the deprecated input model — they were added to Settings later.
Removed the reads (with a comment noting they're only available
via the canonical `settings=...` API); the deprecated input model
is unchanged.
- rtvi/processor.py: two `about: Mapping[str, Any] = None` parameter
signatures — declared `Mapping`, defaulted to `None`, and both
function bodies already handled the None case. Widened to
`Mapping[str, Any] | None = None`.
- aws/stt.py: `subprotocols=["mqtt"]` failed against websockets'
`Sequence[Subprotocol] | None` (Subprotocol is a NewType wrapper).
Wrapped: `subprotocols=[Subprotocol("mqtt")]`.
Files dropped from the ignore list (77 → 67):
processors/frameworks/rtvi/processor.py, services/assemblyai/stt.py,
services/aws/agent_core.py, services/aws/stt.py, services/aws/tts.py,
services/azure/stt.py, services/gradium/stt.py,
services/heygen/api_interactive_avatar.py,
services/openai/responses/llm.py, transports/heygen/transport.py.
Several adjacent fix shapes that together drop 19 files from the
pyrightconfig.json ignore list (96 → 77) and full-pyright errors from
605 → 580. Default pyright stays clean.
TTS voice/context_id None handling — most files in this batch had a
single error of the shape "value typed `T | None` passed where `T` is
required" coming out of `assert_given(self._settings.voice)` (which
strips `_NotGiven` but not `None`) or `get_active_audio_context_id()`.
Two patterns:
- For services where a missing voice means the request can't proceed
(hume, openai, xtts, groq, kokoro, piper), added an explicit None
check. Inside `run_tts` we yield an `ErrorFrame` and return — matching
each service's existing error-emission style (a few wrap `Exception`
broadly and were fine; openai/hume/xtts had narrower or no try blocks
so a bare `raise ValueError` would have escaped uncaught). Piper
validates in `__init__`, where failing fast at construction is the
right shape. OpenAI also gained a `voice not in VALID_VOICES` guard
with a clear message listing supported voices.
- For services where a missing audio context just means "skip this
message" (fish, lmnt, smallest, sarvam, neuphonic), widened
`TTSService.append_to_audio_context`'s `context_id` signature to
`str | None`. The function body already explicitly handled the None
case with a debug log + early return, so the prior `str` annotation
was a lie; making it honest cleared call sites without local guards.
inworld's `_close_context` got the same treatment.
google.genai imports — switched `from google import genai` to
`import google.genai as genai` in google/image.py and google/llm.py.
The dotted form sidesteps a PEP 420 namespace-package stub gap (the
`google` namespace stubs come from a different distribution and don't
declare `genai`), which means pyright now resolves `genai` to the
real module rather than `Unknown`. IDE autocomplete on `genai.<x>`
works for the first time. In image.py this surfaced three latent
bugs that the `Unknown` resolution had been hiding (model was
`str | _NotGiven | None` not narrowed before passing to the SDK; two
spots accessed `.image_bytes` on an `Image | None` without a guard) —
all fixed. llm.py's dotted import surfaced 8 errors (Content-list
typing nuances, internal `_api_client` access, a few small Optionals);
deferred to a future pass since they're outside this commit's scope,
so the file stays in the ignore list with the dotted import.
Latent bug fixes spotted along the way:
- resembleai/tts.py was calling `push_error(ErrorFrame(...))`, but
`push_error` takes a string — there's a separate `push_error_frame`
for the frame case. Switched to the right method.
- openai/base_llm.py: `max_completion_tokens` was the only sibling
field on `OpenAILLMSettings` missing `| None` in its type, which
caused the assignment in openai/llm.py from `params.max_completion_tokens`
(`int | None`) to fail. Added `| None` for consistency with
`max_tokens` etc.
- heygen/base_api.py: `livekit_url: str = None` and `ws_url: str = None`
declared `str` while defaulting to `None`. Removed the bogus
defaults — both fields are required at construction in every
in-tree call site, and the previous `str = None` was a Pydantic
footgun.
Other small ones: gladia/stt.py needed a None guard on `_session_url`
before `websocket_connect`; openrouter/llm.py's
`build_chat_completion_params` override widened to `dict[str, Any]`
diverging from the parent's `OpenAILLMInvocationParams` — restored
the parent's type; neuphonic/tts.py guarded the receive loop's
`async for message in self._websocket` with a local-variable narrowing
matching the pattern from 9e9b1f39e.
groq/tts.py: tightened `output_format`'s typing to
`Literal["flac","mp3","mulaw","ogg","wav"] | str = "wav"`. The literal
side gives IDE autocomplete hints for the currently-supported set;
the `| str` side keeps callers unblocked if groq adds a new format
before this list is updated. A `cast` at the API boundary satisfies
groq's stricter `Literal` parameter type. The literal alias mirrors
the inlined Literal on `groq.resources.audio.speech.AsyncSpeech.create`'s
`response_format` (the SDK doesn't export it as a named symbol).
websocket_service.py: scoped `# pyright: ignore[reportAttributeAccessIssue]`
on `websockets.WebSocketClientProtocol`. That alias is now a deprecated
re-export from the legacy submodule and pyright doesn't surface it
on the top-level `websockets` namespace; runtime is fine. Migrating
to `websockets.ClientConnection` is a separate piece of work
(transports/websocket/client.py uses the same alias four times) and
left for a future commit.
Files dropped from the ignore list: fish/tts.py, gladia/stt.py,
google/image.py, groq/tts.py, heygen/base_api.py, hume/tts.py,
inworld/tts.py, kokoro/tts.py, lmnt/tts.py, neuphonic/tts.py,
openai/llm.py, openai/tts.py, openrouter/llm.py, piper/tts.py,
resembleai/tts.py, sarvam/tts.py, smallest/tts.py,
websocket_service.py, xtts/tts.py.
Same approach as the previous round — apply boundary casts where the
code does dict-style mutation on TypedDict-typed values, narrow at
return sites, and document the LLMSpecificMessage limitation in
realtime adapters that pack history into a single text message.
aws_nova_sonic_adapter.py — pure typing + small narrowing fixes:
- Filter LLMSpecific items in `_from_universal_context_messages`
(documented).
- `_from_universal_context_message` now declared
`-> AWSNovaSonicConversationHistoryMessage | None` (it already had
paths returning None implicitly).
- `get_messages_for_logging` returns `dict[str, Any]` per element
via `dataclasses.asdict`, matching the declared return type.
- Use a local `role` variable so pyright keeps the narrowing across
the truthy-content guard.
grok_realtime_adapter.py / inworld_realtime_adapter.py — same shape
of fix as `open_ai_realtime_adapter.py` from the previous batch.
The two files are essentially copies of the OpenAI Realtime adapter,
so the same template applies: cast at the boundary, filter
LLMSpecificMessage with a documented note, replace the implicit-None
fallthrough with `raise ValueError`, and switch the `text_content +=`
pattern (which fails when one of the parts is None) to a
`text_parts.append(...)` + `" ".join(...)` pattern.
open_ai_adapter.py — pure typing. Cast at the
`OpenAILLMInvocationParams` return, narrow the system-instruction
warning's `initial_content` to `str | None`, and cast the custom-tools
list to `list[ChatCompletionToolParam]`.
open_ai_responses_adapter.py — pure typing. Same shape: narrow
`first_content` to `str | None` for the warning resolver, cast the
constructed dict literals at append sites where the target is
`ResponseInputItemParam`, and cast `get_messages_for_logging`'s
return to the declared `list[dict[str, Any]]`.
processors/aggregators/llm_context.py — pure typing. Cast the
deepcopied message in the redaction loop in `get_messages` to
`dict[str, Any]` and the create_image/audio_message return-dict
literals to `LLMContextMessage`.
Removes 6 newly-clean files from the pyright ignore list.
Net: -77 pyright errors (full-config: 680 -> 603).
Same shape of fix we applied to anthropic_adapter.py earlier — these
adapters do dict-style mutation on values typed as
ChatCompletionMessageParam (a union of TypedDicts) or against Optional
fields. Apply boundary casts (`cast(dict[str, Any], ...)` for the
mutation block, cast back to the TypedDict at return sites). Most
changes are pure typing (rename + cast); a handful in gemini and
openai_realtime are small defensive bug fixes for code paths that
were latently broken by Optional fields slipping through:
perplexity_adapter.py — pure typing. Cast the deepcopied messages to
`list[dict[str, Any]]` for the role-merging / system-conversion /
trailing-assistant-removal transformations and cast back to
ChatCompletionMessageParam at the return.
bedrock_adapter.py — pure typing. Cast the message to
`dict[str, Any]` at the top of `_from_standard_message` for the
tool-result / tool-use / image-content transformations. Cast the
constructed dict at the return site of `get_llm_invocation_params`.
gemini_adapter.py — typing + several None guards on Content.parts and
related Optional fields. Each guard turns a latent
`TypeError`/`AttributeError` (when the type-system-allowed None
showed up at runtime) into a defensive skip — the type annotations
say these can be None and we now handle that.
open_ai_realtime_adapter.py:
- Typing: cast the deepcopied messages, cast back where needed.
- LLMSpecificMessage handling: previously the function would crash on
the first `.get()` call if any LLMSpecificMessage was in the list.
Filter them out and document the limitation — this adapter's
pack-into-single-text-message strategy doesn't compose with opaque
per-provider payloads.
- Real bug fix: `events.ConversationItem` is a Pydantic BaseModel,
not a TypedDict. The bulk-packing path was constructing a raw dict
where a ConversationItem was expected. Replaced with proper
constructor calls (matches what the single-user-message path
already does).
- Real bug fix: `_from_universal_context_message` was declared
`-> events.ConversationItem` but on the unhandled-message
fallthrough it logged and returned None implicitly. Raise
ValueError so the violation is loud, not silent.
Removes 4 newly-clean files from the pyright ignore list:
adapters/services/{perplexity,bedrock,gemini,open_ai_realtime}_adapter.py.
Net: -95 pyright errors (full-config: 775 -> 680).
Six pyright errors followed the same pattern: a value flowed out of
`self._settings.X` (typed `T | _NotGiven`) into a context that wanted
the plain `T`. Wrap each with `assert_given(...)` so the sentinel
gets stripped at the boundary:
- aws/nova_sonic/llm.py: `_settings.model` (in InvokeModel...Input)
and `_settings.system_instruction` (passed to the adapter).
- deepgram/flux/base.py: iterating `_settings.keyterm`.
- google/stt.py: iterating `_settings.languages`.
- google/tts.py: iterating `_settings.speaker_configs`.
- openai/base_llm.py: `_settings.system_instruction` passed to the
adapter.
Also takes a deeper pass at the related Google STT issue: the override
of `language_to_service_language` had been broadened to take
`Language | list[Language]` and return `str | list[str]`, a Liskov
violation against the base's `Language -> str | None` contract.
External callers always pass a single Language, and the only consumer
of the list path was Google STT's own `_get_language_codes`. Restore
the override to a single-Language signature and let
`_get_language_codes` iterate. The override is also tightened to
return `str` (narrower than the base's `str | None`, which is
LSP-compatible) since it always falls back to `"en-US"` rather than
returning None.
Net: -7 pyright errors (full-config run: 782 -> 775).
These provider-specific helpers are all thin wrappers around
`resolve_language(...)`, which itself returns `str` — never `None`.
The `str | None` annotations were misleading and were producing
spurious pyright errors at the call sites that assigned the result
into a `str` field. Update each helper's signature to `str` and
rewrite the `Returns:` docstring to describe the actual fallback
behaviour (resolve to base or full code, with a warning).
Importantly, the per-class `language_to_service_language(...)`
methods on `STTService`/`TTSService` subclasses keep `str | None` as
their return type. That signature is an extension hook for future
and/or third-party subclasses that may genuinely not be able to
produce a code for some languages, even though all in-tree first-
party services currently return a string.
Also includes one small unrelated tightening in azure/stt.py: wrap
`self._settings.language` with `assert_given(...)` so the truthy
fallback to `language_to_azure_language(Language.EN_US)` doesn't
silently swallow a NotGiven sentinel.
Net: -3 pyright errors (full-config run: 785 -> 782).
Pyright flagged 19 sites where `await self._<connection>.send/recv/...`
was called on a receiver typed `X | None`. Each kind of call site
needed a slightly different fix to be both type-safe and behaviour-
preserving:
Streaming/user-facing paths (early return + warn — drop and warn is
the right runtime fail-safe when reconnect didn't succeed):
- cartesia/stt.py (run_stt)
- soniox/stt.py (_send_keepalive)
- elevenlabs/tts.py (run_tts — yields ErrorFrame and returns)
- deepgram/sagemaker/tts.py (run_tts)
- transports/lemonslice/transport.py (send_message)
- transports/tavus/transport.py (send_message)
"Should never happen" cases (early return with comment, no warn —
caller already gated on a separate `_is_*` check, so a warn would be
noise):
- deepgram/flux/stt.py (transport methods, gated by _transport_is_active)
- deepgram/flux/sagemaker/stt.py (same)
- stt_service.py (_send_keepalive, gated by _is_keepalive_ready)
- elevenlabs/stt.py (_send_keepalive, same)
- llm_service.py (_ws_recv — raises ConnectionError to match
_ensure_connected's contract)
- heygen/client.py (receive loop, gated by self._connected)
Just-assigned-above (use a local variable so pyright keeps the
narrowing across statements):
- lmnt/tts.py
- gradium/stt.py
- fish/tts.py
Other:
- transports/websocket/server.py — used the existing local `websocket`
parameter in scope instead of `self._websocket` for the close call.
- websocket_service.py — `send_with_retry` raises ConnectionError when
`self._websocket` is None inside the existing try-block, so the
broad `except Exception` triggers reconnect just as it would on a
real send failure (preserving the prior behaviour where None
silently fell through to the AttributeError-driven reconnect path).
Drops three now-clean files from the pyright ignore list: cartesia/stt.py,
elevenlabs/stt.py, and soniox/stt.py.
After making LLMService generic, an unparameterized subclass
(`class MyService(LLMService):` with no bracket — the third-party
provider pattern) saw `get_llm_adapter()` return `Unknown` rather
than `BaseLLMAdapter` as it did before the refactor.
Add `default=BaseLLMAdapter` (PEP 696) on the TypeVar — via
`typing_extensions.TypeVar` so older Python targets keep working —
so unparameterized callers get `LLMService[BaseLLMAdapter]` and
`get_llm_adapter()` returns `BaseLLMAdapter`, matching the
pre-refactor type precision.
Two internal fallouts of having a default (where the default makes
unannotated `LLMService` resolve invariantly to
`LLMService[BaseLLMAdapter]`):
- `FunctionCallParams.llm` is now `LLMService[Any]` so concrete
parameterizations like `LLMService[OpenAILLMAdapter]` can be
passed where the field is set.
- The explicit `LLMService.__init__(self, **kwargs)` in
`WebsocketLLMService.__init__` gets a `pyright: ignore[reportArgumentType]`
comment — pyright's invariance handling can't see through the
multi-inheritance + generic + default combination, but the
runtime call is correct (generics are erased).
Two follow-ups now that LLMService is generic over its adapter:
- Add an explicit backward-compat test verifying that an LLMService
subclass with no generic parameter (the third-party-provider
pattern) instantiates and returns a usable adapter. The existing
MockLLMService (declared without brackets) already exercised this
implicitly, but it's worth a named assertion.
- Drop the now-redundant `params: SomeLLMInvocationParams = ...`
variable annotations on `adapter.get_llm_invocation_params()`
results. Since `get_llm_adapter()` now returns the precise adapter
type, and `BaseLLMAdapter` is generic in its invocation-params
type, the call already infers the right TypedDict.
Previously, `LLMService.get_llm_adapter()` returned `BaseLLMAdapter`,
which forced every caller that wanted the precise adapter type to
write `adapter: SomeAdapter = self.get_llm_adapter()` and accept
pyright's complaint that the assignment doesn't match the declared
type. That pattern existed in 17 places across the LLM services.
Make `LLMService` generic over its adapter type — `LLMService(...,
Generic[TAdapter])` with `TAdapter = TypeVar("TAdapter",
bound=BaseLLMAdapter)` — so subclasses opt in via
`LLMService[XAdapter]` and callers get the precise type back from
`get_llm_adapter()` automatically.
Backward-compatible for third-party providers: code that says
`class MyService(LLMService):` (no bracket) still type-checks, with
TAdapter resolving to BaseLLMAdapter from the bound — identical to
the pre-refactor behavior. The `adapter_class` attribute keeps its
loose `type[BaseLLMAdapter] = OpenAILLMAdapter` typing so the default
remains usable; one localized cast in `__init__` bridges the loose
class attr to the precise instance attr.
In-tree subclasses opted in:
- AnthropicLLMService -> LLMService[AnthropicLLMAdapter]
- AWSBedrockLLMService -> LLMService[AWSBedrockLLMAdapter]
- AWSNovaSonicLLMService -> LLMService[AWSNovaSonicLLMAdapter]
- BaseOpenAILLMService -> LLMService[OpenAILLMAdapter] (propagates to
~15 OpenAI-compatible providers like Cerebras, Groq, Together)
- GeminiLiveLLMService -> LLMService[GeminiLLMAdapter]
- GoogleLLMService -> LLMService[GeminiLLMAdapter]
- GrokRealtimeLLMService -> LLMService[GrokRealtimeLLMAdapter]
- InworldRealtimeLLMService -> LLMService[InworldRealtimeLLMAdapter]
- OpenAIRealtimeLLMService -> LLMService[OpenAIRealtimeLLMAdapter]
- _BaseOpenAIResponsesLLMService -> LLMService[OpenAIResponsesLLMAdapter]
- WebsocketLLMService is also generic so the multi-inheritance case
(OpenAIResponsesLLMService) can keep both bases agreeing on TAdapter.
All 17 redundant `adapter: SomeAdapter = self.get_llm_adapter()`
annotations are now plain `adapter = self.get_llm_adapter()`.
Same pattern as the earlier get_setup_params fix: when context tools
are absent, the fallback `adapter.from_standard_tools(self._tools)`
can return the NotGiven sentinel, and `_send_prompt_start_event`
expects a list. Coerce via `or []` so the NotGiven case becomes an
empty list.
Three small changes that resolve pyright errors and sharpen the logic:
- Guard `self._context` with the codebase's "should never happen"
early-return pattern, so we don't blindly call `.get_messages()` on
None.
- Skip `LLMSpecificMessage` items in the iteration. They're opaque
provider-specific payloads with no `.get()`, and the surrounding
logic only applies to standard tool-result messages.
- Match `role == "tool"` explicitly. The previous truthy-only check
was working by accident — the `tool_call_id` filter further down
was effectively narrowing to tool messages, but the intent is
clearer when stated upfront.
reset_conversation is part of the public AWSNovaSonicLLMService API and
is also called internally from the receive-task error handler.
Previously it captured `self._context` (typed `LLMContext | None`) and
unconditionally passed it to `_handle_context`, which expects a real
context — silently doing the wrong thing if no initial context had
been received yet.
Treat that as developer error: log a warning and return early. Nothing
to preserve means nothing to reset.
The service implements the NovaSonicSessionSender protocol so the
session-continuation helper can target either the current or next
session. The protocol declares
`get_setup_params(self) -> tuple[str | None, list]`, but the
implementation was unannotated and could return NotGiven in the tools
position when from_standard_tools fell through to its NotGiven
sentinel. Add the matching return annotation and coerce the NotGiven
case to an empty list.
Same MessageParam content-typing issue as the consecutive-message merge
fix: pyright doesn't carry the str-to-list narrowing forward, and
Iterable has no `[-1]` access. Cast to `list[Any]` and document the
chain of assumptions (list, non-empty, dict-typed last item) and where
each is upheld upstream.
This brings anthropic_adapter.py to 0 pyright errors (down from 115).
The function takes an OpenAI ChatCompletionMessageParam (a union of
TypedDicts) and returns an Anthropic MessageParam (a different
TypedDict). It does the conversion via dict-level mutations that don't
type-check against either side's TypedDict schema. Work with the
deepcopied message as a plain dict and cast to MessageParam at the
return sites — matching the boundary-cast convention noted in
llm_context.py.
Drops anthropic_adapter.py from 20 to 2 pyright errors.
The fallback path in `_from_universal_context_message` returns
`message.message` from an `LLMSpecificMessage`, which is typed loosely
(`Any | dict`). The surrounding comment already documents the
assumption that the message is already in Anthropic format — make that
assumption explicit to pyright with a cast.
MessageParam types content as `str | Iterable[...]`, and Iterable has
no `.extend()`. After the str-to-list conversions, pyright re-reads
the TypedDict field as the original wide type rather than carrying the
narrowing forward. Cast to `list[Any]` to express the codebase's
existing str-or-list assumption.
Drops anthropic_adapter.py from 23 to 21 pyright errors.
Content items in MessageParam have a heterogeneous union type (Pydantic
ContentBlock variants and TypedDict *BlockParam variants), neither of
which supports the dict-style access and mutation this sanitizer does.
Treat the deepcopied message as a plain dict and guard each content
item with isinstance(item, dict) — matches the runtime shape produced
by _from_standard_message and avoids crashing if a non-dict ever flows
through the LLMSpecificMessage path.
Drops anthropic_adapter.py from 115 to 23 pyright errors.
Adds a `mip_opt_out` init parameter to both `DeepgramTTSService` (WebSocket)
and `DeepgramHttpTTSService` so callers can opt out of the Deepgram Model
Improvement Program. When set, the value is forwarded as a query parameter
on the request, matching the pattern used by the Deepgram STT services.
Broaden `tool_resources` to `app_resources` for easy access not just in
tool handlers but in other places like custom `FrameProcessor`s.
Involves 3 changes:
- A rename: `tool_resources` -> `app_resources`
- A new property on `PipelineTask`: `app_resources`
- A new property on `FrameProcessor`: `pipeline_task`
Usage in tool handler:
async def get_weather(params: FunctionCallParams):
resources = cast(MyAppResources, params.app_resources)
...
Usage in custom `FrameProcessor`:
class MyProcessor(FrameProcessor):
async def process_frame(self, frame, direction):
await super().process_frame(frame, direction)
if self.pipeline_task is not None:
resources = cast(MyAppResources, self.pipeline_task.app_resources)
...
The previous `tool_resources` aliases (on `PipelineTask`,
`FunctionCallParams`, and `FrameProcessorSetup`) keep working but are
deprecated as of 1.2.0 and emit `DeprecationWarning`s.
The four krisp test files installed a process-wide mock of
importlib.metadata.version with `patch(...).start()` at module level and
never called .stop(). Once any of these files was collected, the mock
leaked across the rest of the test session, returning '0.0.0-dev' for
every version check. This corrupted unrelated tests that triggered
transformers' import-time dependency check (e.g. lazy imports of
LocalSmartTurnAnalyzerV3) — transformers saw tqdm=='0.0.0-dev' and
refused to load.
Wrap the pipecat imports in `with patch(...)` so the mock is active
during import (where pipecat's krisp version check needs it) and torn
down before any tests run.
Importing pipecat.turns.user_turn_strategies pulled in
LocalSmartTurnAnalyzerV3 → transformers → onnxruntime at module load
time. Since this module is imported by llm_response_universal (and
therefore most LLM services), any LLM service import paid the cost of
loading transformers and triggered its missing-backend warning in
environments without PyTorch/TF/Flax.
Move the LocalSmartTurnAnalyzerV3 import into
default_user_turn_stop_strategies() so it only loads when the default
smart-turn strategy is actually constructed.
Fixes#4392
The non-200 branch yielded an ErrorFrame and then raised, which the outer
except caught and yielded a second, less informative "Unknown error" frame.
Return after the yield and fold the status code into the message.
Pyright flagged the .post() call on a possibly-None _session. Raise a
clear RuntimeError if start() wasn't called instead of crashing on the
attribute access.
SPELL/EMOTION_TAG/PAUSE_TAG/VOLUME_TAG/SPEED_TAG are stateless and worked
only via class-level access. Decorating them lets instance access work too
and silences the missing-self lint warning.
- Bump default cartesia_version to 2026-03-01.
- Replace deprecated use_original_timestamps with use_normalized_timestamps
so word timestamps match what was actually spoken.
- Add max_buffer_delay_ms init arg; auto-derive 0 in SENTENCE mode to avoid
the doc-warned "middle ground" of client + server buffering, leave unset
in TOKEN mode for managed buffering.
- Silently consume flush_done messages now emitted per transcript when
server-side buffering is disabled.
Adds a `session_id: str | None` field to `RunnerArguments` so bots can
log/trace a per-session identifier in local development the same way
they can in Pipecat Cloud (where it is provided via the
`x-daily-session-id` header).
The local runner now mints a UUID at every `*RunnerArguments`
construction site. For paths that already returned a `sessionId` to the
caller (Daily `/start`, dial-in webhook), a single UUID is now generated
and shared between `runner_args.session_id` and the response body
instead of being thrown away. The SmallWebRTC `/api/offer` endpoint
accepts an optional `session_id` so the `/sessions/{session_id}/...`
proxy can thread it through.
This is the prerequisite step for collapsing pipecat-cloud's
`SessionArguments` / `*SessionArguments` hierarchy onto the upstream
runner types.
So the rendered changelog has the (PR [...]) line aligned as a list
continuation under its bullet. Verified with both short and wrapped
entries via `towncrier build --draft`.
Introduce SonioxTTSService, a WebSocket TTS provider that streams text and
receives audio over a persistent connection, multiplexing up to 5 concurrent
streams per socket via Soniox's `stream_id`. Also updates the README service
table and the Soniox voice example to use the new TTS end-to-end.
Replaces the hardcoded camera publishing send settings in
DailyTransport with a new DailyParams.camera_out_send_settings dict that
applications can pass through verbatim to the Daily client. This makes
the encoding/codec/bitrate configuration user-controllable instead of
being driven solely by the generic TransportParams fields.
As a consequence, TransportParams.video_out_bitrate is deprecated for
the Daily transport (now configured via camera_out_send_settings) and
its default is changed to None.
Adds a dedicated screen video track alongside the existing camera track
so applications can publish to Daily's built-in "screenVideo" destination
via video_out_destinations. The track is created at join time and wired
into the client settings (inputs and publishing) when "screenVideo" is
configured; write_video_frame routes frames to the appropriate track
based on the frame's transport_destination.
Bound methods are created fresh on each attribute access, so
'self._missing_function_call_handler is self._missing_function_call_handler'
is always False. Using 'is' meant the placeholder branch never fired and
both warnings logged when a function was missing at queue time.
Switch to == so equality compares the underlying function and instance.
Strengthen the missing-at-queue-time test to assert the second warning
does not fire.
Address review feedback: a function may be unregistered between when
run_function_calls queues it and when _run_function_call executes it.
Restore the live lookup, falling back to the missing-function handler
when the entry is gone, so the call still terminates with a normal
tool result. Factor the missing-handler item construction into a
helper since it's now built in two places.
Runner-created Daily rooms previously had no expiration when callers
posted partial `dailyRoomProperties` (e.g. `{"start_video_off": true}`).
The model-default `exp=None` and `eject_at_room_exp=False` meant Daily's
cron never cleaned them up, so rooms accumulated indefinitely.
Encode the policy in the runner: define `PIPECAT_CLOUD_ROOM_EXP_HOURS=4.0`,
inject `exp` and `eject_at_room_exp=True` into user-supplied properties via
`setdefault` (so explicit caller values still win), and pass
`room_exp_duration` to all four `configure()` call sites.

Pipecat 1.0.8 hard-required protobuf 6.x via the base `protobuf>=6.31.1,<7`
pin, blocking users whose dependency graph already constrains protobuf to
the 5.x line. The original bump (PR #4136) was only needed because
`nvidia-riva-client>=2.25.1` ships gencode compiled with protoc 6.31.1.
Changes:
- Widen base pin to `protobuf>=5.29.6,<7`.
- Regenerate `frames_pb2.py` with `grpcio-tools~=1.67.1` (protoc 5.x). Per
Google's cross-version runtime guarantee, 5.x gencode runs on both 5.x
and 6.x runtimes, so this single artifact serves all users.
- Loosen the dev pin `grpcio-tools` to `>=1.67.1,<2` so contributors can
install `pipecat[dev,nvidia]` without resolver conflict. Comment in
`frames.proto` documents the 1.67.x requirement for regeneration.
- Add an explicit `protobuf>=6.31.1,<7` to the `nvidia` extra. This
compensates for nvidia-riva-client's missing `protobuf` install
requirement (upstream packaging gap, see
https://github.com/nvidia-riva/python-clients/issues/172). When that
issue is resolved, the explicit protobuf entry in the `nvidia` extra
can be removed.
Verified: pipecat imports cleanly on both protobuf 5.29.6 and 6.33.6;
`tests/test_protobuf_serializer.py` passes; `import riva.client` succeeds
when `pipecat[nvidia]` is installed.
Nova Sonic sessions have an AWS-imposed ~8-minute time limit. This adds
transparent session continuation that rotates sessions in the background
before the limit is reached, preserving conversation context with no
user-perceptible interruption.
Implementation follows the AWS reference architecture:
- Monitor loop detects when session age exceeds threshold
- On assistant AUDIO contentStart: start buffering user audio, create next
session (sessionStart + promptStart + system instruction)
- Track SPECULATIVE/FINAL text counts as completion signal
- On completion signal: send conversation history + audioInputStart +
buffered audio to next session, then promote immediately
- Close old session in background (non-blocking)
- Dead session detection: recreate next session if idle >30s
Key design decisions:
- Session continuation enabled by default (fundamental for long conversations)
- Conversation history tracked in real-time via _sc_conversation_history
(independent of pipeline context aggregator which updates asynchronously)
- Completion signal check in _handle_content_end_event (after history update)
to ensure latest text is included in handoff
- Rolling audio buffer (default 3s) captures user audio during transition
- transition_threshold_seconds capped at 420s (7min) for safety margin
- Unified event methods (_send_text_event, _send_client_event, etc.) accept
optional stream/prompt_name params, eliminating duplicate SC methods
Also adds:
- SessionContinuationParams config (enabled, threshold, buffer, timeout)
LLMContext's NotGiven, LLMContextToolChoice, and LLMStandardMessage are
currently aliased to their OpenAI equivalents, so passing values
between the two sides type-checks implicitly. That works today but
obscures the fact that these are meant to be conceptually distinct —
if LLMContext ever diverges from OpenAI's types, every implicit
crossing would silently break.
Introduce two module-private cast helpers in open_ai_adapter.py:
- _openai_from_llm_context_tool_choice(tool_choice)
- _openai_from_llm_standard_message(message)
Both are typed no-ops today (implemented with typing.cast) but each
carries a docstring explaining why the cast is present, and every
boundary crossing now routes through a named function. Future readers
(and future greps) can find the crossings; a later divergence becomes
a mechanical find-and-update rather than hunting through adapter code.
No behavior change, no pyright error delta.
After widening TTSSettings.voice to str | None | _NotGiven (so other
TTS services can opt into None as a valid "no voice" state), pyright
flagged Speechmatics' URL builder receiving str | None where it
required str.
Speechmatics has no "no voice" mode (the URL path includes the voice
name), so override the inherited field in SpeechmaticsTTSSettings to
str | _NotGiven. The call site stays as a plain assert_given(...)
without an extra None check.
Three LLM services initialize certain Settings fields with the SDK's
NOT_GIVEN (openai.NOT_GIVEN or anthropic.NOT_GIVEN) so the value
flows unmodified into SDK API calls. The inherited field types from
LLMSettings only admit pipecat's _NotGiven, so pyright flagged each
constructor call as a flavor mismatch.
Widen the field types in each service-specific Settings subclass so
they accept both pipecat's _NotGiven (for delta-mode defaults) and
the corresponding SDK NotGiven (for store-mode passthrough):
- OpenAILLMSettings: frequency_penalty, presence_penalty, seed,
temperature, top_p, max_tokens, max_completion_tokens.
- OpenAIResponsesLLMSettings: temperature, top_p,
max_completion_tokens.
- AnthropicLLMSettings: temperature, top_k, top_p, thinking.
Every overridden field is genuinely read from self._settings and
passed directly to the SDK, so none of the overrides are vestigial.
Clears 21 pyright errors and restores test_service_settings_complete
parity with the pre-NOT_GIVEN-swap state.
asyncai/tts and google/vertex/llm are now clean after the missing-None
sweep (both benefited from the TTSSettings.voice / LLMSettings
cascades).
- src/pipecat/services/asyncai/tts.py
- src/pipecat/services/google/vertex/llm.py
Service-specific Settings subclasses declared fields as T | _NotGiven
(no None), but the services routinely pass None to those fields during
init to mean "don't override — use the vendor's default". The field
type just didn't reflect that a None value is valid, so pyright
flagged every None at the call sites.
Change the declarations to T | None | _NotGiven, matching the pattern
already used by ServiceSettings.model and TTSSettings.language. No
constructor-call changes; the default_factory stays NOT_GIVEN.
Fields touched across 11 files:
- services/settings.py: TTSSettings.voice (base class; covers
asyncai, cartesia, elevenlabs, fish, hume, kokoro, lmnt, mistral,
neuphonic, piper, resembleai, rime, xtts TTS services).
- services/aws/llm.py: latency.
- services/aws/tts.py: engine, pitch, rate, volume, lexicon_names.
- services/azure/tts.py: emphasis, pitch, rate, role, style,
style_degree, volume.
- services/google/gemini_live/llm.py: vad.
- services/google/llm.py: thinking.
- services/google/stt.py: language_codes.
- services/inworld/tts.py: speaking_rate, temperature.
- services/openai/tts.py: instructions, speed.
- services/speechmatics/stt.py: 13 fields (domain, operating_point,
max_delay, end_of_utterance_*, punctuation_overrides, *_partials,
split_sentences, enable_diarization, speaker_*, max_speakers,
prefer_current_speaker, extra_params).
- services/ultravox/llm.py: output_medium.
Clears 94 pyright errors (1035 -> 941).
Three files no longer have pyright errors after the is_given /
assert_given sweep — remove them from the ignore list (which serves as
a live todo of files with remaining type errors).
- src/pipecat/processors/gstreamer/pipeline_source.py
- src/pipecat/services/camb/tts.py

Apply assert_given across service modules to narrow reads from
store-mode settings fields (self._settings.X, default_settings.X),
where _NotGiven is declared in the field type but should never appear
at runtime (enforced by validate_complete()).
Two idioms used:
- Inline wrap for single uses:
func(assert_given(self._settings.enable_prompt_caching), ...)
- Extract-and-reuse when the same value is used multiple times:
thinking = assert_given(self._settings.thinking)
if thinking:
params["thinking"] = thinking.model_dump(...)
43 service files touched. Cleared ~172 pyright errors; remaining
_NotGiven-related errors are in adjacent categories (flavor mismatch
between openai/anthropic NotGiven and pipecat _NotGiven, settings
field types that should allow None but don't) that need different
fixes.
In store-mode settings objects, _NotGiven should never appear (the
invariant enforced by validate_complete). But the declared field types
still include _NotGiven because the same class doubles as delta mode,
so every field read is typed X | None | _NotGiven and pyright flags
operations that assume X | None.
assert_given is a one-line extractor that narrows away _NotGiven and
raises loudly if the invariant is violated — preferable to scattering
is_given guards that defend against something that can't occur in
practice.
resolved_model = assert_given(self._settings.model) # str | None
Replace direct identity checks against NOT_GIVEN with is_given() at
sites where pyright's inability to narrow on non-singleton sentinels
was causing type errors.
- adapters/services/anthropic_adapter.py: narrow converted.system for
_resolve_system_instruction.
- services/openai/llm.py: narrow params.service_tier using OpenAI's
is_given.
- services/sarvam/llm.py: narrow tools / tool_choice using OpenAI's
is_given (aliased as openai_is_given alongside the existing
settings.is_given import).
- services/sarvam/tts.py: narrow settings.voice using settings.is_given.
Pyright can't narrow identity checks against module-level NotGiven
sentinels (they aren't typed as singletons), which leaves many
NotGiven-bearing unions stuck as unnarrowed types throughout the
codebase. Introduce is_given TypeGuard helpers so narrowing works via
isinstance under the hood.
Each helper is co-located with the NotGiven flavor it guards:
- services/settings.py: upgrade the existing is_given to a TypeGuard.
- processors/aggregators/llm_context.py: add an is_given for
LLMContext's NotGiven. Treat LLMContext's re-exported types
(LLMStandardMessage, LLMContextToolChoice, NOT_GIVEN, NotGiven) as
LLMContext's own — independent definitions that happen to coincide
with OpenAI's as an implementation detail.
- adapters/services/anthropic_adapter.py: add is_given for anthropic's
NotGiven.
- adapters/services/open_ai_adapter.py: add is_given for openai's
NotGiven.
TypedDict types are not subtypes of dict[...] in the type system
(per PEP 589), so TypedDict-based invocation param classes could not
satisfy the TypeVar bound. Mapping[str, Any] accepts TypedDicts while
preserving the "string-keyed mapping" constraint.
The original contributor's PR (#4328) landed as #4355. Rename the fragment
so the rendered changelog links to the merged PR, and add the leading `- `
bullet prefix that towncrier expects.
Extends the reconnect re-seeding fix to work cleanly on Gemini Live 2.5,
which has stricter seed requirements than 3.x and a documented audio-input /
history-recall limitation. Both initial connection and reconnect now share a
single code path (`_create_initial_response(for_reconnect=...)`), with four
well-documented cases.
On Gemini 2.5 reconnect, `turn_complete=True` is now forced on the seed so
the model produces a recap-style response immediately instead of briefly
acting "forgetful" on the user's next utterance — the latter being
especially jarring mid-conversation. When a 2.5 seed doesn't already end
with a user turn (e.g. the bot had finished speaking before the disconnect),
a blank user turn is appended to satisfy the server's seed-shape
requirement. Gemini 3.x needs neither workaround.
Tkinter's `Label` only stores `PhotoImage` references at the C level, so
Python GC eats them unless something on the Python side keeps a
reference. The canonical fix is to stash the reference on the widget
itself: `label.image = photo`. Tkinter widgets are plain Python objects,
so the assignment works at runtime, but the stub declares no `image`
attribute (correctly — there isn't one; we're adding it).
Narrow the suppression to `# type: ignore[attr-defined]` on the one
line. The existing comment above the assignment already documents why.
Mistral imposes three conversation-history quirks on top of the
OpenAI-compatible wire format: tool messages must be followed by an
assistant message; non-initial system messages are rejected; trailing
assistant messages require `prefix=True`. These rules were applied
inline in `MistralLLMService.build_chat_completion_params`, which is the
wrong layer — every other provider with OpenAI-compatible-but-quirky
shape (Perplexity, etc.) owns its transformations in a
`BaseLLMAdapter` subclass that runs during `get_llm_invocation_params`.
Create `MistralLLMAdapter(OpenAILLMAdapter)` on the Perplexity template
and wire it in via the existing `adapter_class` dispatch. The service
now only handles Mistral-specific request-level mapping (`random_seed`
in place of `seed`), and the message shape concerns live with other
provider format logic.
No behavior change. The transform function casts to `list[dict[str,
Any]]` internally because mutating `role` and attaching Mistral's
non-standard `prefix` field both step outside OpenAI's TypedDict
contract; the cast at the return boundary encodes that we're emitting
Mistral's extended schema, not OpenAI's.
`inspect.getdoc()` returns `str | None`, but `docstring_parser.parse()`
requires `str`. Functions without a docstring produced `None`, which
the type checker correctly flagged.
Coerce to `""` at the call site. `docstring_parser.parse("")` returns
an empty docstring whose `.description` and `.params` are already
handled by the surrounding `or ""` fallbacks, so runtime behavior is
unchanged.
`ToolsSchema.__init__` declared `standard_tools: list[FunctionSchema |
DirectFunction]`. Callers (`BaseLLMAdapter`, `MCPService`) pass in
`list[FunctionSchema]`, which is not assignable to the union list
because `list` is invariant in its element type.
Widen the parameter to `Sequence[...]` (covariant) so `list[X]` and
`list[X | Y]` both fit. A narrower `list[FunctionSchema]` is still
accepted, and nothing in this class mutates the argument — the
constructor immediately copies it via `_map_standard_tools`.
Also correct the `custom_tools` property return type to include
`None`, matching the stored `_custom_tools` field.
This single edit clears the pyright errors for three ignore-list
entries: `tools_schema.py`, `base_llm_adapter.py`, and `mcp_service.py`.
Two services were reading `_settings.model` (typed `str | _NotGiven |
None` because NOT_GIVEN is the default) and coercing it with `or ""`
or similar. `_NotGiven.__bool__` returns False, so the runtime
behavior happened to work, but the type was a lie — pyright saw
`str | _NotGiven` flowing into APIs that required `str` or `str | None`.
- `AIService._sync_model_name_to_metrics`: use `isinstance(model, str)`
narrowing with an empty-string fallback. Equivalent runtime behavior,
honest type, no truthiness dependency on a sentinel.
- `SarvamLLMService.__init__`: validate the model is a real string
before handing it to `_validate_model(str)`. A non-string model at
this point is a configuration bug; raise `ValueError` so the error
is clear and survives `python -O` (unlike an assert).
Three spots had the same shape: a field starts None, a later method
populates it, a read site later reads it. Pyright can't track the
cross-method invariant. Rather than spray assertions at the read
sites, fix each site at the structural level:
- `FastAPIWebsocketInputTransport._monitor_websocket` now takes the
session timeout as an argument. The task-creation site already
guards on truthiness, so the call can pass the non-None value
directly and the method's signature tells the truth.
- `FrameProcessorMetrics.task_manager` raises `RuntimeError` instead
of asserting. Asserts are stripped under `python -O`; a real raise
keeps the runtime safety net and still narrows the type for pyright.
- `SOXRStreamAudioResampler._maybe_initialize_sox_stream` returns the
initialized stream. Callers use the return value and never touch
the Optional `_soxr_stream` attribute, so narrowing stays inside
the init method where the invariant is established.
`ImageGenService.run_image_gen` and `VisionService.run_vision` were
declared `async def ... -> AsyncGenerator[Frame, None]` with `pass`
bodies. Without a `yield` anywhere in the body, Python treats the
function as a coroutine returning an `AsyncGenerator`, not as an async
generator itself, so callers got a coroutine where they expected an
iterator.
Add `raise NotImplementedError; yield` so the body contains a yield
(making this a real async generator) while still raising cleanly if a
subclass ever calls `super().run_*` by mistake.
Deepgram STT, Gradium TTS, Smallest STT, and xAI STT/TTS had exactly
one pyright error each, all of them the AsyncGenerator return-type
mismatch resolved in 08fe9157c. Remove them from the ignore list.
AssemblyAI, Cartesia, Gradium, and Soniox STT services sent audio over
the WebSocket without catching transient send failures, so a single
network hiccup could propagate an exception up through process_frame
and end the pipeline. Other push-based STT services (Deepgram, xAI,
Azure, Smallest, etc.) already guard their sends.
Follow the deepgram/stt.py pattern: log a warning and continue. The
existing connection-state check at the top of each call handles
recovery on the next invocation.
The push-based STT/TTS implementations send audio/text over a socket and
receive results via a separate receive task, so there is nothing to
yield inline. They yield `None` by design. The previous declaration of
`AsyncGenerator[Frame, None]` disagreed with that, while the consumer
(`AIService.process_generator`) already accepted `Frame | None`. Widen
the producer side (abstract base and every subclass) so the type honestly
describes the contract.
Pure annotation change; no runtime behavior difference.
Previously, six modules (adapters, audio, processors, serializers,
services, transports) were ignored wholesale. Many files in those
modules already pass type checking, but we had no way to protect them
from regressions or make the remaining work visible.
Switch the include list to src/pipecat so any new module is checked by
default, and replace directory-level ignores with the 140 specific
files that still fail. This puts 189 previously-untyped files under
type checking immediately and turns the remaining work into a concrete,
shrinking TODO list.
Moves src/pipecat/serializers into pyright's include list. Narrows
self._params to each subclass's InputParams in exotel, vonage, plivo,
twilio, genesys, and telnyx. In protobuf.py, renames the reassigned
frame local to avoid clobbering its Frame type and silences two dynamic
attribute accesses on the generated frames_pb2 module.
Also aligns telnyx and plivo hangup validation with twilio: if
auto_hang_up=True (the default) but required credentials are missing,
__init__ now raises ValueError instead of silently logging a warning
at call-end time. Previously a misconfigured serializer would construct
fine and fail to hang up the call later, leaving a phantom billable
session.
Collapse the separate fallback timer into the existing user_speech_timeout
timer, restarted when a transcript arrives without a VAD stop. stt_timeout
has no meaning on the fallback path, so the stt wait is marked done
immediately. This drops the _fallback_timeout_task / _fallback_expired
bookkeeping and the branched trigger condition.
Adds XAITTSService in the existing xai/tts.py module, alongside the
existing XAIHttpTTSService. Connects to xAI's streaming endpoint at
wss://api.x.ai/v1/tts, streams text.delta chunks up and base64 audio.delta
chunks down on the same connection so audio starts flowing before the full
utterance is synthesized.
Extends InterruptibleTTSService since xAI's protocol is strictly sequential
per connection and exposes neither a cancel verb nor a context ID — the
only way to stop an in-flight utterance is to tear down the WebSocket,
which is exactly what InterruptibleTTSService does on interruption when
the bot is speaking.
Voice, language, codec, and sample_rate are passed as query-string params
at connect time; runtime setting changes reconnect the socket. Defaults to
raw PCM so emitted TTSAudioRawFrame objects need no decoding downstream.
Splits the existing example into voice-xai.py (WebSocket) and
voice-xai-http.py (batch HTTP) so each variant has its own entry point.
Promotes the xai extra to depend on pipecat-ai[websockets-base] since the
new service imports the websockets library.
Remove `examples/` from the `pyrightconfig.json` ignore list and fix
the resulting type errors across all example files. Common fixes:
- Required API keys: `os.getenv("X")` -> `os.environ["X"]` so the
return type is `str` rather than `str | None`, and misconfiguration
fails fast.
- Narrow `LLMContextMessage` union members with `isinstance(..., dict)`
before dict-style access.
- `assert isinstance(params.llm, ...)` before calling service-specific
methods that aren't on the base `LLMService`.
- Guard optional frame fields (e.g. `LLMSearchResponseFrame.search_result`)
before use.
If the WebSocket handshake is cancelled or fails before `keepalive_task`
is assigned (e.g. an STTUpdateSettingsFrame triggers a reconnect during
initial connect), the `finally` block tried to cancel an unbound local.
Initialize `keepalive_task = None` before the try and guard the cancel.
New `XAISTTService` wraps xAI's real-time speech-to-text WebSocket
(`wss://api.x.ai/v1/stt`). It extends `WebsocketSTTService`, authenticates
with the `XAI_API_KEY` as a Bearer token on the WS handshake, and streams
raw audio (PCM/mu-law/A-law) with configurable interim results, endpointing,
language, multichannel, and diarization settings.
- `src/pipecat/services/xai/stt.py`: new service, settings dataclass, and
`language_to_xai_stt_language` helper.
- `src/pipecat/services/stt_latency.py`: `XAI_TTFS_P99` default.
- `pyproject.toml` / `uv.lock`: `xai` extra now pulls in `websockets-base`.
- `README.md`: link to xAI STT in the services table.
- `examples/voice/voice-xai.py`: swap DeepgramSTTService for XAISTTService so
the xAI voice example is fully xAI.
- `examples/transcription/transcription-xai.py`: new transcription-only
example using the new service.
SpeechTimeoutUserTurnStopStrategy previously collapsed two waits into
max(stt_timeout, user_speech_timeout), which over-waited for finalizing
STT services and could also end the turn early in a legacy code path.
Run them as independent timers instead:
- user_speech_timeout: policy floor, always runs to completion.
- stt_timeout: latency safety net, short-circuited by a finalized
transcript since STT has signaled it has nothing more to send.
The no-VAD fallback now waits only user_speech_timeout rather than
max(stt_timeout, user_speech_timeout); stt_timeout is defined relative
to VAD stop and has no meaning when no VAD event occurred. This
shortens the fallback wait for users who set stt_timeout greater than
user_speech_timeout.
* Fix Smallest AI TTS WebSocket endpoint URL to match API documentation
Update base URL from waves-api.smallest.ai to api.smallest.ai and
fix path prefix from /api/v1/ to /waves/v1/ per the v4.0.0 docs.
* Update keepalive using silent space message instead of unsupported flush
Pylance analyzes open files even when they're outside the `include`
set, producing noise in the editor. Adding these paths to `ignore`
suppresses diagnostics without affecting import resolution.
Some TTS providers (e.g. Inworld) return verbatim tokens where spaces and
punctuation are already embedded in the token text. When downstream consumers
join these tokens with an extra space they produce "hello , world" instead of
"hello, world".
Add an opt-in `includes_inter_frame_spaces: bool = False` parameter to
`add_word_timestamps` / `_add_word_timestamps`. The flag is threaded through
`_WordTimestampEntry` and stamped onto every emitted `TTSTextFrame`.
Defaults to `False` — no behaviour change for existing services.
`InworldTTSService` passes `includes_inter_frame_spaces=True` and stops
pre-processing tokens in `_calculate_word_times`, returning them verbatim.
Tests added to `test_tts_frame_ordering.py` covering both HTTP and WebSocket
delivery paths: verbatim text preservation, PTS ordering, text-before-audio
ordering, and the Inworld punctuation-token scenario.
Made-with: Cursor
The two logger.error lines in krisp_instance.py fired at module-load time
whenever anything transitively imported it (e.g. pipecat.turns.user_start
pulling in krisp_viva_ip_user_turn_start_strategy), producing noisy output
for users who never asked for Krisp. Drop the log calls and raise a more
informative ImportError that names the affected classes so direct
importers still get clear guidance.
- Fall back to Language.EN in _primary_detected_language when model is
flux-general-en, preserving prior behavior on the default model.
- Standardize example on DeepgramFluxSTTService.Settings and drop the
now-redundant DeepgramFluxSTTSettings import.
- Narrow the changed-behavior changelog to reflect that flux-general-en
frames still carry Language.EN.
Enables the flux-general-multi model with one or more language_hints.
Hints are sent as repeatable URL params at connect time and via a
Configure control message when updated mid-stream (detect-then-lock).
TranscriptionFrame.language now reflects the language Flux detected
for each turn via the TurnInfo `languages` field.
Add changelog entries for the pyright introduction and the
LiveKitRunnerArguments.token signature tightening. Restore the
indented multi-line format for the WhatsApp missing-env error,
now listing only the vars that are actually missing.
Make required parameters non-optional: LiveKitRunnerArguments.token,
_create_telephony_transport args. Use os.environ[] instead of
os.getenv() for required WhatsApp env vars. Guard spec/loader None
in module loading. Tighten sip_caller_phone guard in daily.py.

SentryMetrics.stop_ttfb_metrics and stop_processing_metrics called the
base FrameProcessorMetrics implementation but discarded its return
value (implicit `return None`). FrameProcessorMetrics.stop_ttfb_metrics
/ stop_processing_metrics build and return a MetricsFrame, which
FrameProcessor.stop_ttfb_metrics / stop_processing_metrics then pushes
downstream so observers (e.g. UserBotLatencyObserver,
MetricsLogObserver) can see TTFB / processing metrics.
Because SentryMetrics returned None, the FrameProcessor never pushed
the MetricsFrame, so any pipeline using metrics=SentryMetrics() on STT
/ LLM / TTS services silently lost all downstream TTFB and processing
MetricsFrames. The metrics were still calculated and logged
internally, and Sentry transactions still finished correctly, but
observers never saw them.
Forward the MetricsFrame returned by the base class so FrameProcessor
can push it into the pipeline.
Use Sequence[FrameProcessor] instead of list[FrameProcessor] in Pipeline,
ServiceSwitcher, and ServiceSwitcherStrategy parameters to accept subtype
lists. Add cast() in LLMSwitcher for narrowed return types. Guard against
None in task_observer._send_to_proxy and replace hasattr with truthiness
check in task._cleanup.
Widen base strategy process_frame return types to ProcessFrameResult |
None to match actual behavior (None treated as CONTINUE). Give
UserTurnCompletionLLMServiceMixin a FrameProcessor base class so pyright
can see create_task, cancel_task, process_frame, and push_frame.
Tighten LLMMessagesAppendFrame and LLMMessagesUpdateFrame message fields
from list[dict] to list[LLMContextMessage] to match actual usage. Add
type annotations on inline message lists in IVR navigator and voicemail
detector.
In token-streaming mode, _push_tts_frames previously stripped only
leading newlines and dropped any pure-whitespace frame. That silently
discarded meaningful inter-token whitespace (e.g. a standalone "\n"
token between "hello" and "world"), losing prosody cues and any
downstream sentence-boundary semantics.
Track whether a non-whitespace character has been sent in the current
context. While the flag is false, strip all leading whitespace; once
true, let whitespace tokens flow through. Reset the flag on
LLMFullResponseEndFrame/EndFrame and on interruption, and save/restore
it around TTSSpeakFrame since each utterance is its own context.
Sentence-aggregation mode preserves the existing behavior.
Group three co-assigned fields (_start_frame_id, _start_frame_arrival_ns,
_start_wall_clock) into a single _StartFrameInfo dataclass. This makes
the "always set together" invariant structural rather than implicit, and
fixes the incorrect str | None annotation on _start_frame_id (Frame.id
is int).
Add pyrightconfig.json with basic type checking for zero-error modules
(clocks, metrics, transcriptions, frames) and enforce via CI. The
include list will expand as modules are fixed.
* Improve HeyGen LiveAvatar plugin reliability and performance
- Add WebSocket ready gate: wait for session.state_updated connected
event before sending commands (prevents silently dropped messages)
- Add keep-alive mechanism: send session.keep_alive every 2.5 min to
prevent 5-minute inactivity timeout
- Optimize audio chunking: 600ms first chunk for faster initial
response, 1s subsequent chunks for efficient streaming
- Fix audio buffer flush: send remaining buffered audio on utterance
end instead of discarding it
- Fix WS state cleanup: properly reset connected/ready state when
WebSocket drops unexpectedly
- Add livekit_config passthrough in LiveAvatar session token creation
- Replace stray print() with logger.debug()
* Fix HeyGenOutputTransport.start() signature and use 400ms first chunk
- Update transport.py to match new client.start() signature (no
audio_chunk_size param)
- Change first chunk size from 600ms to 400ms per feedback
* Fix transport audio resampling and client.start() error propagation
- Add audio resampling in HeyGenOutputTransport.write_audio_frame() to
ensure audio is always 24kHz before sending to HeyGen (was sending
at pipeline sample rate, causing garbled audio)
- Raise exception on WS ready timeout instead of silently returning,
preventing transport from appearing ready when WS connection failed
* Fix session readiness gate to work with LITE mode
LITE mode does not send session.state_updated WS events. Instead,
use a dual-signal _session_ready event that fires on either:
- WS session.state_updated connected (FULL mode)
- LiveKit participant connected (LITE mode)
Also reorder start() to connect both WS and LiveKit before waiting,
since the WS events may depend on LiveKit being connected.
Verified with live sandbox session - all tests pass.
* Simplify session readiness to use only WS ready gate
Remove _session_ready dual-signal and use only _ws_ready, which fires
on the session.state_updated connected WS event. Increase timeout to
30s. LiveKit is connected before waiting so the WS event can arrive.
* Reduce WS ready gate timeout back to 10s
* Remove WS ready gate (session.state_updated not reliably received)
The session.state_updated connected event is not reliably received
via the websockets library. Remove the gate for now and assume the
session is ready after WS + LiveKit connect. Keep-alive, chunking,
buffer flush, state cleanup, and other improvements remain.
Mirrors the existing `from_string` classmethod and lets callers
turn a frame's `buttons` list back into a dial string like `"123#"`.
`__str__` and the Daily transport's native DTMF path reuse it.
The single-key `button` field on `OutputDTMFFrame` and
`OutputDTMFUrgentFrame` is kept as a first-class ergonomic shortcut
for the common single-keypress case, equivalent to
`buttons=[button]`. `buttons` takes precedence when both are set.
Replaces the string-based `tones` field with a type-safe
`buttons: list[KeypadEntry]` on `OutputDTMFFrame` and
`OutputDTMFUrgentFrame`, matching the existing singular `button`
field on `InputDTMFFrame`. A `from_string` classmethod builds the
list from a dial string like `"123#"` (invalid characters raise
ValueError from the `KeypadEntry` constructor).
The base output audio fallback now iterates `frame.buttons`
directly, LiveKit sends `frame.buttons[0].value`, and the Daily
transport joins the button values into the single string Daily's
`send_dtmf` expects.
Introduces a new `tones` field on `OutputDTMFFrame` and
`OutputDTMFUrgentFrame` for sending multi-digit DTMF sequences and
deprecates the existing single-key `button` field. When only `button`
is set, it is used as a single-character `tones` string for backward
compatibility.
`DTMFFrame` is kept as an empty marker class so both input and output
DTMF frames can still be identified via isinstance. `InputDTMFFrame`
keeps its required `button` field (single keypress semantics).
The Daily-specific `DailyOutputDTMFFrame` and
`DailyOutputDTMFUrgentFrame` frames no longer need to override
`button` and simply add `session_id` and `digit_duration_ms`, which
are forwarded to Daily's `send_dtmf` as `sessionId` and
`digitDurationMs`.
The base output audio fallback now iterates `tones` and generates a
tone per character; LiveKit's native DTMF path sends `tones[0]` since
its API is single-tone.
Introduces Daily-specific DTMF output frames that carry explicit
`tones`, `session_id` and `digit_duration_ms` fields, forwarded to
Daily's `send_dtmf` as `tones`, `sessionId` and `digitDurationMs`.
The inherited `button` and `transport_destination` fields are
ignored for these frames in the Daily transport.

- Fixed `pipecat-ai[tavus]` not installing the required `daily-python` dependency. Installing the `tavus` extra now correctly pulls in `pipecat-ai[daily]`.
- Added a `session_id` field to `RunnerArguments` so bots can log or trace a per-session identifier in local development the same way they can in Pipecat Cloud. The development runner now mints a UUID at every construction site, and paths that already returned a `sessionId` to the caller (Daily `/start`, dial-in webhook) share that same UUID with the runner args instead of generating two. The SmallWebRTC `/api/offer` endpoint also accepts an optional `session_id` query parameter so the `/sessions/{session_id}/...` proxy can thread it through.
- Added a `max_buffer_delay_ms` constructor argument to `CartesiaTTSService` for controlling Cartesia's server-side text buffering. When unset, Pipecat picks a sensible default based on `text_aggregation_mode`: `0` in `SENTENCE` mode (custom buffering — avoids stacking client-side aggregation on top of Cartesia's default 3000ms server buffer) and unset in `TOKEN` mode (Cartesia's managed buffering applies). Pass an explicit value (0–5000ms) to override.
- Default `cartesia_version` for `CartesiaTTSService` bumped from `2025-04-16` to `2026-03-01`, matching `CartesiaHttpTTSService` and unlocking the `use_normalized_timestamps` and `max_buffer_delay_ms` fields.
- ⚠️ `CartesiaTTSService` now sends `use_normalized_timestamps: true` instead of the deprecated `use_original_timestamps` field. Word timestamps now reflect what was actually spoken (post text-normalization and pronunciation-dictionary substitution), matching the convention Pipecat uses for ElevenLabs. This is a behavior change for `sonic-3` users, who were previously receiving timestamps tied to the input transcript.
- Fixed `CartesiaHttpTTSService` pushing two `ErrorFrame`s on a non-200 response — one with the API's error text and a second, less informative "Unknown error" frame from the outer exception handler. It now pushes a single frame that includes the HTTP status code and returns cleanly.
- Fixed Cartesia tag helpers (`SPELL`, `EMOTION_TAG`, `PAUSE_TAG`, `VOLUME_TAG`, `SPEED_TAG`) raising `TypeError` when called on an instance (e.g. `tts.SPELL("hi")`). They're now `@staticmethod` and callable from both the class and an instance.
- Fixed `CartesiaTTSService` surfacing `flush_done` messages from Cartesia as `ErrorFrame`s. The latest API emits a `flush_done` per transcript when server-side buffering is disabled; Pipecat now consumes them silently since each turn already has its own `context_id`.
- Fixed an issue where `LocalSmartTurnAnalyzerV3` was imported unconditionally for user turn stop strategies. It is now only imported when `default_user_turn_stop_strategies()` is called. This improves startup time and removes the `transformers` "PyTorch/TensorFlow/Flax not found" warning when the default stop strategies are not used.
- Broadened `tool_resources` to `app_resources` for easy access not just in tool handlers but in other places like custom `FrameProcessor`s. Three changes: a rename (`tool_resources` → `app_resources`), a new `app_resources` property on `PipelineTask`, and a new `pipeline_task` property on `FrameProcessor`. Tool handlers now read `params.app_resources`; custom processors read `self.pipeline_task.app_resources`. The previous `tool_resources` aliases (on `PipelineTask`, `FunctionCallParams`, and `FrameProcessorSetup`) keep working but are deprecated as of 1.2.0 and emit `DeprecationWarning`s.
- Added a `mip_opt_out` constructor argument to `DeepgramTTSService` and `DeepgramHttpTTSService` so callers can opt out of the Deepgram Model Improvement Program. When set, the value is forwarded to Deepgram as a query parameter on the speak request. Defaults to `None`, which preserves the existing behavior. See https://dpgr.am/deepgram-mip for pricing implications before enabling.
- Added support to `AWSNovaSonicLLMService` for the new "async tool call" mechanism activated by `cancel_on_interruption=False`, which includes delivering results asynchronously, delivering result streams, and cancelling running async tools. Support for the other major realtime services (`GeminiLiveLLMService`, `OpenAIRealtimeLLMService`) will be added in a follow-up PR.
- Fixed a regression in `AWSNovaSonicLLMService` where `cancel_on_interruption=False` (which previously worked under the old async-tool-call mechanism, by simply avoiding discarding tool calls on interruptions) stopped working after the introduction of the new "async tool call" mechanism.
