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.
