Add changelog entry for PR #3802

Replace `pipecat-ai[local-smart-turn-v3]` in main dependencies with
the actual packages (transformers, onnxruntime) to eliminate the
circular dependency that causes Poetry to error with:
"Package 'pipecat-ai[local-smart-turn-v3]' is listed as a dependency of itself."

-
-            ## Setup
-
-            1. Read the skill instructions at `.claude/skills/update-docs/SKILL.md`
-            2. Read the source-to-doc mapping at `.claude/skills/update-docs/SOURCE_DOC_MAPPING.md`
-            3. The docs repository is checked out at `./_docs/`
-
-            ## Get the diff
-
-            Run `gh pr diff ${{ steps.pr.outputs.number }}` to see what changed in the PR.
-            Also run `gh pr diff ${{ steps.pr.outputs.number }} --name-only` to get the list of changed files.
-            Filter to source files matching the directories listed in SKILL.md Step 3.
-
-            If no relevant source files were changed, exit with "No documentation changes needed."
-
-            ## Follow the skill instructions
-
-            Apply the SKILL.md workflow (Steps 3-9) with these adaptations for automation:
-
-            ### Docs path
-            Use `./_docs/` — it's already checked out. Do not ask for a path.
-
-            ### Branch management
-            - Branch name: `docs/pr-${{ steps.pr.outputs.number }}`
-            - Work inside `./_docs/` for all doc edits and git operations
-            - Check if the branch already exists on the remote:
-              ```bash
-              cd _docs && git fetch origin docs/pr-${{ steps.pr.outputs.number }} 2>/dev/null
-              ```
-              - If it exists: check it out (supports workflow re-runs)
-              - If not: create it from main
-
-            ### Git config
-            Before committing in `_docs`, set:
-            ```bash
-            git config user.name "github-actions[bot]"
-            git config user.email "github-actions[bot]@users.noreply.github.com"
-            ```
-
-            ### No interactive questions
-            Do not ask questions. If you encounter gaps (unmapped files, missing sections,
-            ambiguous changes), note them in the PR body under "## Gaps identified".
-
-            ### Creating the docs PR
-            After committing all changes in `_docs`, push and create a PR:
-            ```bash
-            cd _docs
-            git push -u origin docs/pr-${{ steps.pr.outputs.number }}
-            GH_TOKEN=$DOCS_SYNC_TOKEN gh pr create \
-              --repo pipecat-ai/docs \
-              --label auto-docs \
-              --title "docs: update for pipecat PR #${{ steps.pr.outputs.number }}" \
-              --body "$(cat <<'BODY'
-            Automated documentation update for [pipecat PR #${{ steps.pr.outputs.number }}](https://github.com/pipecat-ai/pipecat/pull/${{ steps.pr.outputs.number }}).
-
-            ## Changes
-            <summarize each doc page updated and what changed>
-
-            ## Gaps identified
-            <any unmapped files, missing doc pages, or missing sections — or "None">
-            BODY
-            )"
-            ```
-
-            ### Re-run handling
-            If `gh pr create` fails because a PR from that branch already exists,
-            push the updated commits and use `gh pr edit` to update the body instead.
-
-            ### No-op
-            If after analyzing the diff you determine no documentation changes are needed
-            (e.g., only skip-listed files changed, or changes don't affect public API docs),
-            exit cleanly without creating a branch or PR. Output "No documentation changes needed."
-
-            ## Important rules
-            - Only modify files inside `./_docs/` — never modify pipecat source code
-            - Follow the conservative editing rules from SKILL.md Step 6
-            - Read each doc page fully before editing (SKILL.md Guidelines)
-            - Use `GH_TOKEN=$DOCS_SYNC_TOKEN` for all `gh` commands targeting pipecat-ai/docs

-  (PR [#3831](https://github.com/pipecat-ai/pipecat/pull/3831))

-  policies can be implemented via the `on_service_switched` event handler.
-  (PR [#3861](https://github.com/pipecat-ai/pipecat/pull/3861))
-
-- Added optional `timeout_secs` parameter to `register_function()` and
-  `register_direct_function()` for per-tool function call timeout control,
-  overriding the global `function_call_timeout_secs` default.
-  (PR [#3915](https://github.com/pipecat-ai/pipecat/pull/3915))

-- Added `cloud-audio-only` recording option to Daily transport's
-  `enable_recording` property.
-  (PR [#3916](https://github.com/pipecat-ai/pipecat/pull/3916))
-
-- Wired up `system_instruction` in `BaseOpenAILLMService`,
-  `AnthropicLLMService`, and `AWSBedrockLLMService` so it works as a default
-  system prompt, matching the behavior of the Google services. This enables
-  sharing a single `LLMContext` across multiple LLM services, where each
-  service provides its own system instruction independently.
-

-    ```
-  (PR [#3918](https://github.com/pipecat-ai/pipecat/pull/3918))
-
-- Added `vad_threshold` parameter to `AssemblyAIConnectionParams` for
-  configuring voice activity detection sensitivity in U3 Pro. Aligning this
-  with external VAD thresholds (e.g., Silero VAD) prevents the "dead zone"
-  where AssemblyAI transcribes speech that VAD hasn't detected yet.
-  (PR [#3927](https://github.com/pipecat-ai/pipecat/pull/3927))
-
-- Added `push_empty_transcripts` parameter to `BaseWhisperSTTService` and
-  `OpenAISTTService` to allow empty transcripts to be pushed downstream as
-  `TranscriptionFrame` instead of discarding them (the default behavior). This
-  is intended for situations where VAD fires even though the user did not
-  speak. In these cases, it is useful to know that nothing was transcribed so
-  that the agent can resume speaking, instead of waiting longer for a
-  transcription.
-  (PR [#3930](https://github.com/pipecat-ai/pipecat/pull/3930))
-
-- LLM services (`BaseOpenAILLMService`, `AnthropicLLMService`,
-  `AWSBedrockLLMService`) now log a warning when both `system_instruction` and
-  a system message in the context are set. The constructor's
-  `system_instruction` takes precedence.
-  (PR [#3932](https://github.com/pipecat-ai/pipecat/pull/3932))
-
-- Runtime settings updates (via `STTUpdateSettingsFrame`) now work for AWS
-  Transcribe, Azure, Cartesia, Deepgram, ElevenLabs Realtime, Gradium, and
-  Soniox STT services. Previously, changing settings at runtime only stored the
-  new values without reconnecting.
-  (PR [#3946](https://github.com/pipecat-ai/pipecat/pull/3946))
-
-- Exposed `on_summary_applied` event on `LLMAssistantAggregator`, allowing
-  users to listen for context summarization events without accessing private
-  members.
-  (PR [#3947](https://github.com/pipecat-ai/pipecat/pull/3947))
-
-- Deepgram Flux STT settings (`keyterm`, `eot_threshold`,
-  `eager_eot_threshold`, `eot_timeout_ms`) can now be updated mid-stream via
-  `STTUpdateSettingsFrame` without triggering a reconnect. The new values are
-  sent to Deepgram as a Configure WebSocket message on the existing connection.
-  (PR [#3953](https://github.com/pipecat-ai/pipecat/pull/3953))
-
-- Added `system_instruction` parameter to `run_inference` across all LLM
-  services, allowing callers to override the system prompt for one-shot
-  inference calls. Used by `_generate_summary` to pass the summarization prompt
-  cleanly.
-  (PR [#3968](https://github.com/pipecat-ai/pipecat/pull/3968))
-
-### Changed
-
-- Audio context management (previously in `AudioContextTTSService`) is now
-  built into `TTSService`. All WebSocket providers (`cartesia`, `elevenlabs`,
-  `asyncai`, `inworld`, `rime`, `gradium`, `resembleai`) now inherit from
-  `WebsocketTTSService` directly. Word-timestamp baseline is set automatically
-  on the first audio chunk of each context instead of requiring each provider
-  to call `start_word_timestamps()` in their receive loop.
-  (PR [#3804](https://github.com/pipecat-ai/pipecat/pull/3804))
-
-- Daily transport now uses `CustomVideoSource`/`CustomVideoTrack` instead of
-  `VirtualCameraDevice` for the default camera output, mirroring how audio
-  already works with `CustomAudioSource`/`CustomAudioTrack`.
-  (PR [#3831](https://github.com/pipecat-ai/pipecat/pull/3831))
-
-- ⚠️ Updated `DeepgramSTTService` to use `deepgram-sdk` v6. The `LiveOptions`
-  class was removed from the SDK and is now provided by pipecat directly;
-  import it from `pipecat.services.deepgram.stt` instead of `deepgram`.
-  (PR [#3848](https://github.com/pipecat-ai/pipecat/pull/3848))
-
-- `ServiceSwitcherStrategy` base class now provides a `handle_error()` hook for
-  subclasses to implement error-based switching. `ServiceSwitcher` defaults to
-  `ServiceSwitcherStrategyManual` and `strategy_type` is now optional.
-  (PR [#3861](https://github.com/pipecat-ai/pipecat/pull/3861))
-
-- Support for Voice Focus 2.0 models.
-    - Updated `aic-sdk` to `~=2.1.0` to support Voice Focus 2.0 models.
-    - Cleaned unused `ParameterFixedError` exception handling in `AICFilter`
-      parameter setup.
-  (PR [#3889](https://github.com/pipecat-ai/pipecat/pull/3889))
-
-- `max_context_tokens` and `max_unsummarized_messages` in
-  `LLMAutoContextSummarizationConfig` (and deprecated
-  `LLMContextSummarizationConfig`) can now be set to `None` independently to
-  disable that summarization threshold. At least one must remain set.
-  (PR [#3914](https://github.com/pipecat-ai/pipecat/pull/3914))
-
-- ⚠️ Removed `formatted_finals` and `word_finalization_max_wait_time` from
-  `AssemblyAIConnectionParams` as these were v2 API parameters not supported in
-  v3. Clarified that `format_turns` only applies to Universal-Streaming models;
-  U3 Pro has automatic formatting built-in.
-  (PR [#3927](https://github.com/pipecat-ai/pipecat/pull/3927))
-
-- Changed `DeepgramTTSService` to send a Clear message on interruption instead
-  of disconnecting and reconnecting the WebSocket, allowing the connection to
-  persist throughout the session.
-  (PR [#3958](https://github.com/pipecat-ai/pipecat/pull/3958))
-
-- Re-added `enhancement_level` support to `AICFilter` with runtime
-  `FilterEnableFrame` control, applying `ProcessorParameter.Bypass` and
-  `ProcessorParameter.EnhancementLevel` together.
-  (PR [#3961](https://github.com/pipecat-ai/pipecat/pull/3961))
-
-- Updated `daily-python` dependency from `~=0.23.0` to `~=0.24.0`.
-  (PR [#3970](https://github.com/pipecat-ai/pipecat/pull/3970))
-
-- Updated `FishAudioTTSService` default model from `s1` to `s2-pro`, matching
-  Fish Audio's latest recommended model for improved quality and speed.
-  (PR [#3973](https://github.com/pipecat-ai/pipecat/pull/3973))
-
-- `AzureSTTService` `region` parameter is now optional when `private_endpoint`
-  is provided. A `ValueError` is raised if neither is given, and a warning is
-  logged if both are provided (`private_endpoint` takes priority).
-  (PR [#3974](https://github.com/pipecat-ai/pipecat/pull/3974))
-
-### Deprecated
-
-- Deprecated `AudioContextTTSService` and `AudioContextWordTTSService`.
-  Subclass `WebsocketTTSService` directly instead; audio context management is
-  now part of the base `TTSService`.
-  - Deprecated `WordTTSService`, `WebsocketWordTTSService`, and
-    `InterruptibleWordTTSService`. Word timestamp logic is now always active in
-    `TTSService` and no longer needs to be opted into via a subclass.
-  (PR [#3804](https://github.com/pipecat-ai/pipecat/pull/3804))
-
-- Deprecated `pipecat.services.google.llm_vertex`,
-  `pipecat.services.google.llm_openai`, and
-  `pipecat.services.google.gemini_live.llm_vertex` modules. Use
-  `pipecat.services.google.vertex.llm`, `pipecat.services.google.openai.llm`,
-  and `pipecat.services.google.gemini_live.vertex.llm` instead. The old import
-  paths still work but will emit a `DeprecationWarning`.
-  (PR [#3980](https://github.com/pipecat-ai/pipecat/pull/3980))
-
-### Removed
-
-- ⚠️ Removed `supports_word_timestamps` parameter from `TTSService.__init__()`.
-  Word timestamp logic is now always active. Remove this argument from any
-  custom subclass `super().__init__()` calls.
-  (PR [#3804](https://github.com/pipecat-ai/pipecat/pull/3804))
-
-### Fixed
-
-- Fixed `DeepgramSTTService` keepalive ping timeout disconnections. The
-  deepgram-sdk v6 removed automatic keepalive; pipecat now sends explicit
-  `KeepAlive` messages every 5 seconds, within the recommended 3–5 second
-  interval before Deepgram's 10-second inactivity timeout.
-  (PR [#3848](https://github.com/pipecat-ai/pipecat/pull/3848))
-
-- Fixed `BufferError: Existing exports of data: object cannot be re-sized` in
-  `AICFilter` caused by holding a `memoryview` on the mutable audio buffer
-  across async yield points.
-  (PR [#3889](https://github.com/pipecat-ai/pipecat/pull/3889))
-
-- Fixed TTS context not being appended to the assistant message history when
-  using `TTSSpeakFrame` with `append_to_context=True` with some TTS providers.
-  (PR [#3936](https://github.com/pipecat-ai/pipecat/pull/3936))
-
-- Fixed context summarization leaving orphaned tool responses in the kept
-  context when tool calls were moved to the summarized portion.
-  (PR [#3937](https://github.com/pipecat-ai/pipecat/pull/3937))
-
-- Fixed turn completion state not resetting at end of LLM responses.
-  `LLMFullResponseEndFrame` is pushed (not received) by the LLM service, so the
-  mixin now handles it in `push_frame` instead of `process_frame`.
-  (PR [#3956](https://github.com/pipecat-ai/pipecat/pull/3956))
-
-- Fixed turn completion instructions being injected as a context system message
-  instead of using `system_instruction`. This caused warning spam when
-  `system_instruction` was also set and didn't persist across full context
-  updates.
-  (PR [#3957](https://github.com/pipecat-ai/pipecat/pull/3957))
-
-- Fixed `TTSService` audio context queue getting blocked when
-  `append_to_audio_context()` was called with a `None` context ID, which
-  prevented subsequent audio from being delivered.
-  (PR [#3958](https://github.com/pipecat-ai/pipecat/pull/3958))
-
-- Fixed `on_call_state_updated` event handler in LiveKit transport receiving
-  incorrect number of arguments due to redundant `self` passed to
-  `_call_event_handler`.
-  (PR [#3959](https://github.com/pipecat-ai/pipecat/pull/3959))
-
-- Fixed OpenAI Realtime, OpenAI Realtime Beta, and Grok realtime services
-  treating `conversation_already_has_active_response` as a fatal error. These
-  services now log it as a non-fatal debug event when a response is already in
-  progress.
-  (PR [#3960](https://github.com/pipecat-ai/pipecat/pull/3960))
-
-- Fixed `SmallWebRTCConnection` silently discarding messages sent before the
-  data channel is open by queuing them and flushing once the channel is ready.
-  A bounded queue (`MAX_MESSAGE_QUEUE_SIZE = 50`) prevents unbounded memory
-  growth, and a 10-second timeout after connection clears the queue and falls
-  back to discard mode if the data channel never opens.
-  (PR [#3962](https://github.com/pipecat-ai/pipecat/pull/3962))
-
-- Fixed `AzureSTTService` failing to initialize when `private_endpoint` is
-  provided. The Azure Speech SDK's `SpeechConfig` does not accept both `region`
-  and `endpoint` simultaneously, so they are now passed conditionally.
-  (PR [#3967](https://github.com/pipecat-ai/pipecat/pull/3967))
-
-- Fixed `GoogleLLMService` ignoring the `system_instruction` set via
-  constructor or `GoogleLLMSettings` when a system message was also present in
-  the context. The settings value now correctly takes priority, and a warning
-  is logged when both are set.
-  (PR [#3976](https://github.com/pipecat-ai/pipecat/pull/3976))
-
-### Other
-
-- Updated foundational examples to use `system_instruction` on LLM services
-  instead of adding system messages to `LLMContext`.
-  (PR [#3918](https://github.com/pipecat-ai/pipecat/pull/3918))
-
-- Updated AssemblyAI turn detection example to use `keyterms_prompt` list
-  format instead of `prompt` string for improved clarity.
-  (PR [#3929](https://github.com/pipecat-ai/pipecat/pull/3929))
-
-- Updated foundational examples and eval scripts to use `"user"` role instead
-  of `"system"` when adding messages to `LLMContext`, since system prompts
-  should be set via `system_instruction` on the LLM service.
-  (PR [#3931](https://github.com/pipecat-ai/pipecat/pull/3931))
-
-## [0.0.104] - 2026-03-02
-
-### Added
-
-- Added `TextAggregationMetricsData` metric measuring the time from the first
-  LLM token to the first complete sentence, representing the latency cost of
-  sentence aggregation in the TTS pipeline.
-  (PR [#3696](https://github.com/pipecat-ai/pipecat/pull/3696))
-
-- Added support for using strongly-typed objects instead of dicts for updating
-  service settings at runtime.
-
-    Instead of, say:
-
-    ```python
-    await task.queue_frame(
-        STTUpdateSettingsFrame(settings={"language": Language.ES})
-    )
-    ```
-
-    you'd do:
-
-    ```python
-    await task.queue_frame(
-        STTUpdateSettingsFrame(delta=DeepgramSTTSettings(language=Language.ES))
-    )
-    ```
-
-  Each service now vends strongly-typed classes like `DeepgramSTTSettings`
-  representing the service's runtime-updatable settings.
-  (PR [#3714](https://github.com/pipecat-ai/pipecat/pull/3714))
-
-- Added support for specifying private endpoints for Azure Speech-to-Text,
-  enabling use in private networks behind firewalls.
-  (PR [#3764](https://github.com/pipecat-ai/pipecat/pull/3764))
-
-- Added `LemonSliceTransport` and `LemonSliceApi` to support adding real-time
-  LemonSlice Avatars to any Daily room.
-  (PR [#3791](https://github.com/pipecat-ai/pipecat/pull/3791))
-
-- Added `output_medium` parameter to `AgentInputParams` and
-  `OneShotInputParams` in Ultravox service to control initial output medium
-  (text or voice) at call creation time.
-  (PR [#3806](https://github.com/pipecat-ai/pipecat/pull/3806))
-
-- Added `TurnMetricsData` as a generic metrics class for turn detection, with
-  e2e processing time measurement. `KrispVivaTurn` now emits `TurnMetricsData`
-  with `e2e_processing_time_ms` tracking the interval from VAD
-  speech-to-silence transition to turn completion.
-  (PR [#3809](https://github.com/pipecat-ai/pipecat/pull/3809))
-
-- Added `on_audio_context_interrupted()` and `on_audio_context_completed()`
-  callbacks to `AudioContextTTSService`. Subclasses can override these to
-  perform provider-specific cleanup instead of overriding
-  `_handle_interruption()`.
-  (PR [#3814](https://github.com/pipecat-ai/pipecat/pull/3814))
-
-- Added `on_summary_applied` event to `LLMContextSummarizer` for observability,
-  providing message counts before and after context summarization.
-  (PR [#3855](https://github.com/pipecat-ai/pipecat/pull/3855))
-
-- Added `summary_message_template` to `LLMContextSummarizationConfig` for
-  customizing how summaries are formatted when injected into context (e.g.,
-  wrapping in XML tags).
-  (PR [#3855](https://github.com/pipecat-ai/pipecat/pull/3855))
-
-- Added `summarization_timeout` to `LLMContextSummarizationConfig` (default
-  120s) to prevent hung LLM calls from permanently blocking future
-  summarizations.
-  (PR [#3855](https://github.com/pipecat-ai/pipecat/pull/3855))
-
-- Added optional `llm` field to `LLMContextSummarizationConfig` for routing
-  summarization to a dedicated LLM service (e.g., a cheaper/faster model)
-  instead of the pipeline's primary model.
-  (PR [#3855](https://github.com/pipecat-ai/pipecat/pull/3855))
-
-- Add AssemblyAI u3-rt-pro model support with built-in turn detection mode
-  (PR [#3856](https://github.com/pipecat-ai/pipecat/pull/3856))
-
-- Added `LLMSummarizeContextFrame` to trigger on-demand context summarization
-  from anywhere in the pipeline (e.g. a function call tool). Accepts an
-  optional `config: LLMContextSummaryConfig` to override summary generation
-  settings per request.
-  (PR [#3863](https://github.com/pipecat-ai/pipecat/pull/3863))
-
-- Added `LLMContextSummaryConfig` (summary generation params:
-  `target_context_tokens`, `min_messages_after_summary`,
-  `summarization_prompt`) and `LLMAutoContextSummarizationConfig` (auto-trigger
-  thresholds: `max_context_tokens`, `max_unsummarized_messages`, plus a nested
-  `summary_config`). These replace the monolithic
-  `LLMContextSummarizationConfig`.
-  (PR [#3863](https://github.com/pipecat-ai/pipecat/pull/3863))
-
-- Added support for the `speed_alpha` parameter to the `arcana` model in
-  `RimeTTSService`.
-  (PR [#3873](https://github.com/pipecat-ai/pipecat/pull/3873))
-
-- Added `ClientConnectedFrame`, a new `SystemFrame` pushed by all transports
-  (Daily, LiveKit, FastAPI WebSocket, WebSocket Server, SmallWebRTC, HeyGen,
-  Tavus) when a client connects. Enables observers to track transport readiness
-  timing.
-  (PR [#3881](https://github.com/pipecat-ai/pipecat/pull/3881))
-
-- Added `StartupTimingObserver` for measuring how long each processor's
-  `start()` method takes during pipeline startup. Also measures transport
-  readiness — the time from `StartFrame` to first client connection — via the
-  `on_transport_timing_report` event.
-  (PR [#3881](https://github.com/pipecat-ai/pipecat/pull/3881))
-
-- Added `BotConnectedFrame` for SFU transports and `on_transport_timing_report`
-  event to `StartupTimingObserver` with bot and client connection timing.
-  (PR [#3881](https://github.com/pipecat-ai/pipecat/pull/3881))
-
-- Added optional `direction` parameter to `PipelineTask.queue_frame()` and
-  `PipelineTask.queue_frames()`, allowing frames to be pushed upstream from the
-  end of the pipeline.
-  (PR [#3883](https://github.com/pipecat-ai/pipecat/pull/3883))
-
-- Added `on_latency_breakdown` event to `UserBotLatencyObserver` providing
-  per-service TTFB, text aggregation, user turn duration, and function call
-  latency metrics for each user-to-bot response cycle.
-  (PR [#3885](https://github.com/pipecat-ai/pipecat/pull/3885))
-
-- Added `on_first_bot_speech_latency` event to `UserBotLatencyObserver`
-  measuring the time from client connection to first bot speech. An
-  `on_latency_breakdown` is also emitted for this first speech event.
-  (PR [#3885](https://github.com/pipecat-ai/pipecat/pull/3885))
-
-- Added `broadcast_interruption()` to `FrameProcessor`. This method pushes an
-  `InterruptionFrame` both upstream and downstream directly from the calling
-  processor, avoiding the round-trip through the pipeline task that
-  `push_interruption_task_frame_and_wait()` required.
-  (PR [#3896](https://github.com/pipecat-ai/pipecat/pull/3896))
-
-### Changed
-
-- Added `text_aggregation_mode` parameter to `TTSService` and all TTS
-  subclasses with a new `TextAggregationMode` enum (`SENTENCE`, `TOKEN`). All
-  text now flows through text aggregators regardless of mode, enabling pattern
-  detection and tag handling in TOKEN mode.
-  (PR [#3696](https://github.com/pipecat-ai/pipecat/pull/3696))
-
-- ⚠️ Refactored runtime-updatable service settings to use strongly-typed
-  classes (`TTSSettings`, `STTSettings`, `LLMSettings`, and service-specific
-  subclasses) instead of plain dicts. Each service's `_settings` now holds
-  these strongly-typed objects. For service maintainers, see changes in
-  COMMUNITY_INTEGRATIONS.md.
-  (PR [#3714](https://github.com/pipecat-ai/pipecat/pull/3714))
-
-- Word timestamp support has been moved from `WordTTSService` into `TTSService`
-  via a new `supports_word_timestamps` parameter. Services that previously
-  extended `WordTTSService`, `AudioContextWordTTSService`, or
-  `WebsocketWordTTSService` now pass `supports_word_timestamps=True` to their
-  parent `__init__` instead.
-  (PR [#3786](https://github.com/pipecat-ai/pipecat/pull/3786))
-
-- Improved Ultravox TTFB measurement accuracy by using VAD speech end time
-  instead of `UserStoppedSpeakingFrame` timing.
-  (PR [#3806](https://github.com/pipecat-ai/pipecat/pull/3806))
-
-- Aligned `UltravoxRealtimeLLMService` frame handling with OpenAI/Gemini
-  realtime services: added `InterruptionFrame` handling with metrics cleanup,
-  processing metrics at response boundaries, and improved agent transcript
-  handling for both voice and text output modalities.
-  (PR [#3806](https://github.com/pipecat-ai/pipecat/pull/3806))
-
-- Updated `OpenAIRealtimeLLMService` default model to `gpt-realtime-1.5`.
-  (PR [#3807](https://github.com/pipecat-ai/pipecat/pull/3807))
-
-- Added `api_key` parameter to `KrispVivaSDKManager`, `KrispVivaTurn`, and
-  `KrispVivaFilter` for Krisp SDK v1.6.1+ licensing. Falls back to
-  `KRISP_VIVA_API_KEY` environment variable.
-  (PR [#3809](https://github.com/pipecat-ai/pipecat/pull/3809))
-
-- Bumped `nltk` minimum version from 3.9.1 to 3.9.3 to resolve a security
-  vulnerability.
-  (PR [#3811](https://github.com/pipecat-ai/pipecat/pull/3811))
-
-- `ServiceSettingsUpdateFrame`s are now `UninterruptibleFrame`s. Generally
-  speaking, you don't want a user interruption to prevent a service setting
-  change from going into effect. Note that you usually don't use
-  `ServiceSettingsUpdateFrame` directly, you use one of its subclasses:
-    - `LLMUpdateSettingsFrame`
-    - `TTSUpdateSettingsFrame`
-    - `STTUpdateSettingsFrame`
-  (PR [#3819](https://github.com/pipecat-ai/pipecat/pull/3819))
-
-- Updated context summarization to use `user` role instead of `assistant` for
-  summary messages.
-  (PR [#3855](https://github.com/pipecat-ai/pipecat/pull/3855))
-
-- Rename `AssemblyAISTTService` parameter
-  `min_end_of_turn_silence_when_confident` parameter to `min_turn_silence` (old
-  name still supported with deprecation warning)
-  (PR [#3856](https://github.com/pipecat-ai/pipecat/pull/3856))
-
-- ⚠️ Renamed `LLMAssistantAggregatorParams` fields:
-  `enable_context_summarization` → `enable_auto_context_summarization` and
-  `context_summarization_config` → `auto_context_summarization_config` (now
-  accepts `LLMAutoContextSummarizationConfig`). The old names still work with a
-  `DeprecationWarning` for one release cycle.
-  (PR [#3863](https://github.com/pipecat-ai/pipecat/pull/3863))
-
-- `ElevenLabsRealtimeSTTService` now sets `TranscriptionFrame.finalized` to
-  `True` when using `CommitStrategy.MANUAL`.
-  (PR [#3865](https://github.com/pipecat-ai/pipecat/pull/3865))
-
-- Updated numba version pin from == to >=0.61.2
-  (PR [#3868](https://github.com/pipecat-ai/pipecat/pull/3868))
-
-- Updated tracing code to use `ServiceSettings` dataclass API
-  (`given_fields()`, attribute access) instead of dict-style access
-  (`.items()`, `in`, subscript).
-  (PR [#3879](https://github.com/pipecat-ai/pipecat/pull/3879))
-
-- ⚠️ Removed `event` field and `complete()` method from `InterruptionFrame`.
-  Removed `event` field from `InterruptionTaskFrame`. These are no longer
-  needed since `broadcast_interruption()` does not require a round-trip
-  completion signal.
-  (PR [#3896](https://github.com/pipecat-ai/pipecat/pull/3896))
-
-- Moved `pipecat.services.deepgram.stt_sagemaker` and
-  `pipecat.services.deepgram.tts_sagemaker` to
-  `pipecat.services.deepgram.sagemaker.stt` and
-  `pipecat.services.deepgram.sagemaker.tts`. The old import paths still work
-  but emit a `DeprecationWarning`.
-  (PR [#3902](https://github.com/pipecat-ai/pipecat/pull/3902))
-
-### Deprecated
-
-- ⚠️ Deprecated `aggregate_sentences` parameter on `TTSService` and all TTS
-  subclasses. Use `text_aggregation_mode=TextAggregationMode.SENTENCE` or
-  `text_aggregation_mode=TextAggregationMode.TOKEN` instead.
-  (PR [#3696](https://github.com/pipecat-ai/pipecat/pull/3696))
-
-- Deprecated `set_model()`, `set_voice()`, and `set_language()` on AI services
-  in favor of runtime updates via `TTSUpdateSettingsFrame`,
-  `STTUpdateSettingsFrame`, and `LLMUpdateSettingsFrame`.
-
-  ⚠️ Note, too, a subtle behavior change in these deprecated methods. Whereas
-  previously only `set_language()` caused the service to actually react to the
-  update (e.g. by reconnecting to a remote service so it an pick up the
-  change), now all these methods do. This change was made as part of a refactor
-  making them all work the same way under the hood.
-  (PR [#3714](https://github.com/pipecat-ai/pipecat/pull/3714))
-
-- Dict-based `*UpdateSettingsFrame(settings={...})` is deprecated in favor of
-  passing typed settings delta objects with
-  `*UpdateSettingsFrame(delta={...})`.
-  (PR [#3714](https://github.com/pipecat-ai/pipecat/pull/3714))
-
-- Deprecated `WordTTSService`, `WebsocketWordTTSService`,
-  `AudioContextWordTTSService`, and `InterruptibleWordTTSService`. Use their
-  non-word counterparts with `supports_word_timestamps=True` instead:
-    - `WordTTSService` → `TTSService(supports_word_timestamps=True)`
-    - `WebsocketWordTTSService` →
-  `WebsocketTTSService(supports_word_timestamps=True)`
-    - `AudioContextWordTTSService` →
-  `AudioContextTTSService(supports_word_timestamps=True)`
-    - `InterruptibleWordTTSService` →
-  `InterruptibleTTSService(supports_word_timestamps=True)`
-  (PR [#3786](https://github.com/pipecat-ai/pipecat/pull/3786))
-
-- Deprecated `SmartTurnMetricsData` in favor of `TurnMetricsData`.
-  `BaseSmartTurn` now emits `TurnMetricsData` directly.
-  (PR [#3809](https://github.com/pipecat-ai/pipecat/pull/3809))
-
-- Deprecated `LLMContextSummarizationConfig`. Use
-  `LLMAutoContextSummarizationConfig` with a nested `LLMContextSummaryConfig`
-  instead. The old class emits a `DeprecationWarning`.
-  (PR [#3863](https://github.com/pipecat-ai/pipecat/pull/3863))
-
-- Deprecated `push_interruption_task_frame_and_wait()` in `FrameProcessor`. Use
-  `broadcast_interruption()` instead. The old method now delegates to
-  `broadcast_interruption()` and logs a deprecation warning.
-  (PR [#3896](https://github.com/pipecat-ai/pipecat/pull/3896))
-
-### Removed
-
-- Removed `local-smart-turn-v3` optional extra from `pyproject.toml`. The
-  `transformers` and `onnxruntime` packages are now always installed as core
-  dependencies since they are required by the default turn stop strategy,
-  `TurnAnalyzerUserTurnStopStrategy` which uses `LocalSmartTurnAnalyzerV3`.
-  (PR [#3803](https://github.com/pipecat-ai/pipecat/pull/3803))
-
-- ⚠️ Removed `PlayHTTTSService` and `PlayHTHttpTTSService`. PlayHT has been
-  shut down and is no longer available.
-  (PR [#3838](https://github.com/pipecat-ai/pipecat/pull/3838))
-
-### Fixed
-
-- Added `LLMSpecificMessage` handling in `LLMContextSummarizationUtil` to skip
-  provider-specific messages during context summarization.
-  (PR [#3794](https://github.com/pipecat-ai/pipecat/pull/3794))
-
-- Treated `response_cancel_not_active` as a non-fatal error in realtime
-  services (`OpenAIRealtimeLLMService`, `GrokRealtimeLLMService`,
-  `OpenAIRealtimeBetaLLMService`) to prevent WebSocket disconnection when
-  cancelling an inactive response.
-  (PR [#3795](https://github.com/pipecat-ai/pipecat/pull/3795))
-
-- Fixed Poetry compatibility by inlining `local-smart-turn-v3` dependencies
-  (`transformers`, `onnxruntime`) into core dependencies instead of using a
-  self-referential extra.
-  (PR [#3803](https://github.com/pipecat-ai/pipecat/pull/3803))
-
-- Fixed `SentryMetrics` method signatures to match updated
-  `FrameProcessorMetrics` base class, resolving `TypeError` when using
-  `start_time`/`end_time` keyword arguments.
-  (PR [#3808](https://github.com/pipecat-ai/pipecat/pull/3808))
-
-- Fixed STT TTFB metrics not being reported for `SonioxSTTService` and
-  `AWSTranscribeSTTService` due to missing `can_generate_metrics()` override.
-  (PR [#3813](https://github.com/pipecat-ai/pipecat/pull/3813))

 ## Code Style
 
 - **Docstrings**: Google-style. Classes describe purpose; `__init__` has `Args:` section; dataclasses use `Parameters:` section.
 - **Linting**: Ruff (line length 100). Pre-commit hooks enforce formatting.
 - **Type hints**: Required for complex async code.
-- **Dataclass vs Pydantic**: Use `@dataclass` for frames and internal pipeline data (high-frequency, no validation needed). Use Pydantic `BaseModel` for configuration, parameters, metrics, and external API data (benefits from validation and serialization). Specifically:
-  - `@dataclass`: Frame types, context aggregator pairs, internal data containers
-  - `BaseModel`: Service `InputParams`, transport/VAD/turn params, metrics data, API request/response models, serializer params

-### Service Settings
+### Dynamic Settings Updates
 
-Every AI service (STT, LLM, TTS, image generation, etc.) exposes a **Settings dataclass** that serves two roles:
-
-1. **Store mode** — the service's `self._settings` holds the current value of every runtime-updatable field.
-2. **Delta mode** — an update frame (e.g. `TTSUpdateSettingsFrame`) specifies only the fields that should change; unspecified fields remain `NOT_GIVEN`.
-
-#### Defining your Settings class
-
-Extend `STTSettings`, `TTSSettings`, `LLMSettings`, or `ImageGenSettings` (or, if your service directly subclasses `AIService`, `ServiceSettings`). The base classes already provide common fields (e.g. `model`, `voice`, `language`). You only need to add **service-specific knobs that should be runtime-updatable**:
+STT, LLM, and TTS services support `ServiceUpdateSettingsFrame` for dynamic configuration changes. The base STTService has an `_update_settings()` method that handles settings, and the private `_settings` `Dict` is used to store settings and provide access to the subclass.
 
 ```python
-from dataclasses import dataclass, field
+async def set_language(self, language: Language):
+    """Set the recognition language and reconnect.
 
-from pipecat.services.settings import TTSSettings, NOT_GIVEN
-
-@dataclass
-class MyTTSSettings(TTSSettings):
-    """Settings for MyTTS service.
-
-    Parameters:
-        speaking_rate: Speed multiplier (0.5–2.0).
+    Args:
+        language: The language to use for speech recognition.
     """
-
-    speaking_rate: float | None = field(default_factory=lambda: NOT_GIVEN)
-```
-
-**What goes in Settings vs. `__init__` params:**
-
-| Belongs in Settings                                      | Stays as `__init__` params                |
-| -------------------------------------------------------- | ----------------------------------------- |
-| Model name, voice, language                              | API keys, auth tokens                     |
-| Service-specific tuning knobs (rate, pitch, temperature) | Base URLs, endpoint overrides             |
-| Anything users may want to change mid-session            | Audio encoding, sample format             |
-|                                                          | Connection parameters (timeouts, retries) |
-
-The rule of thumb: if a caller might send an update frame to change it at runtime, it belongs in Settings. Everything else is init-only config stored as `self._xxx`.
-
-#### Wiring settings into `__init__`
-
-Accept an **optional** `settings` parameter. Build a `default_settings` object with all fields set to real values, then merge any caller overrides with `apply_update`.
-
-Add a `Settings` **class attribute** that points to your settings dataclass. This lets callers access the settings class through the service itself (e.g. `MyTTSService.Settings(...)`) without a separate import:
-
-```python
-from typing import Optional
-
-class MyTTSService(TTSService):
-    Settings = MyTTSSettings
-    _settings: MyTTSSettings
-
-    def __init__(
-        self,
-        *,
-        api_key: str,
-        settings: Optional[MyTTSSettings] = None,
-        **kwargs,
-    ):
-        # 1. Defaults — every field has a real value (store mode).
-        default_settings = MyTTSSettings(
-            model="my-model-v1",
-            voice="default-voice",
-            language="en",
-            speaking_rate=1.0,
-        )
-
-        # 2. Merge caller overrides (only given fields win).
-        if settings is not None:
-            default_settings.apply_update(settings)
-
-        # 3. Pass the fully-populated settings to the base class.
-        super().__init__(settings=default_settings, **kwargs)
-
-        # 4. Init-only config stored separately.
-        self._api_key = api_key
-```
-
-This pattern lets callers override only what they care about:
-
-```python
-# Uses all defaults
-svc = MyTTSService(api_key="sk-xxx")
-
-# Overrides just the voice — access Settings through the service class
-svc = MyTTSService(
-    api_key="sk-xxx",
-    settings=MyTTSService.Settings(voice="custom-voice"),
-)
-```
-
-#### Reacting to runtime changes
-
-AI services support runtime configuration changes via `*UpdateSettingsFrame`s (e.g. `STTUpdateSettingsFrame`, `TTSUpdateSettingsFrame`, `LLMUpdateSettingsFrame`).
-
-To react to runtime setting changes, override `_update_settings`. The base implementation applies the delta to `self._settings` and returns a `dict` mapping each changed field name to its **pre-update** value. Your override should call `super()` first, then act on the changed fields. A common implementation might look like:
-
-```python
-async def _update_settings(self, update: TTSSettings) -> dict[str, Any]:
-    """Apply a settings update, reconfiguring the connection if needed."""
-    changed = await super()._update_settings(update)
-
-    if not changed:
-        return changed
-
+    logger.info(f"Switching STT language to: [{language}]")
+    self._settings["language"] = language
     await self._disconnect()
     await self._connect()
-
-    return changed
 ```
 
-The dict keys work like a set for membership tests (`"language" in changed`) and truthiness (`if changed`). Use `changed.keys() - {"language"}` for set difference, or `changed["language"]` to inspect the previous value of a field.
-
-Note that, in this example, the service requires a reconnect to apply the new language. Consider, for each setting, whether your service requires reconnection or can apply changes in-place.
-
-If your service can't yet apply certain settings at runtime, call `self._warn_unhandled_updated_settings(changed)` with any unhandled field names so users get a clear log message:
-
-```python
-async def _update_settings(self, update: TTSSettings) -> dict[str, Any]:
-    changed = await super()._update_settings(update)
-
-    if not changed:
-        return changed
-
-    if "language" in changed:
-        await self._update_language()
-    else:
-        # TODO: this should be temporary - handle changes to other settings soon!
-        self._warn_unhandled_updated_settings(changed.keys() - {"language"})
-
-    return changed
-```
+Note that, in this example, Deepgram requires the websocket connection be disconnected and reconnected to reinitialize the service with the new value. Consider if your service requires reconnection.

-
-    This example demonstrates using AssemblyAI's u3-rt-pro Speech-to-Text model
-    with AssemblyAI's built-in turn detection for more natural conversation flow.
-
-    Key features:
-
-    1. AssemblyAI Turn Detection
-       - Set `vad_force_turn_endpoint=False` to use AssemblyAI's built-in turn detection
-       - AssemblyAI's model determines when user starts/stops speaking
-       - Uses `ExternalUserTurnStrategies` to delegate turn control to AssemblyAI
-       - More natural turn detection based on speech patterns and pauses
-
-    2. Advanced Turn Detection Tuning
-       - `min_turn_silence`: Minimum silence (ms) when confident about end-of-turn.
-         Lower values = faster responses. Default: 100ms
-       - `max_turn_silence`: Maximum silence (ms) before forcing end-of-turn.
-         Prevents long pauses. Default: 1000ms
-
-    3. Prompt-Based Transcription Enhancement
-       - Use `prompt` parameter to improve accuracy for specific names/terms
-       - Particularly useful for proper nouns, technical terms, domain vocabulary
-       - Example: "Names: Xiomara, Saoirse, Krzystof. Technical terms: API, OAuth."
-
-    4. Speaker Diarization (Optional)
-       - Enable with `speaker_labels=True`
-       - Automatically identifies different speakers in multi-party conversations
-       - TranscriptionFrame includes speaker_id field (e.g., "Speaker A", "Speaker B")
-
-    5. Language Detection (Optional, multilingual model only)
-       - Enable with `language_detection=True`
-       - Automatically detects spoken language
-       - Available with universal-streaming-multilingual model
-
-    For more information: https://www.assemblyai.com/docs/speech-to-text/streaming
