pipecat-ai/pipecat v0.0.106

on GitHub

Added

• Added optional service field to ServiceUpdateSettingsFrame (and its subclasses LLMUpdateSettingsFrame, TTSUpdateSettingsFrame, STTUpdateSettingsFrame) to target a specific service instance. When service is set, only the matching service applies the settings; others forward the frame unchanged. This enables updating a single service when multiple services of the same type exist in the pipeline.
  (PR #4004)

• Added sip_provider and room_geo parameters to configure() in the Daily runner. These convenience parameters let callers specify a SIP provider name and geographic region directly without manually constructing DailyRoomProperties and DailyRoomSipParams.
  (PR #4005)

• Added PerplexityLLMAdapter that automatically transforms conversation messages to satisfy Perplexity's stricter API constraints (strict role alternation, no non-initial system messages, last message must be user/tool). Previously, certain conversation histories could cause Perplexity API errors that didn't occur with OpenAI (PerplexityLLMService subclasses OpenAILLMService since Perplexity uses an OpenAI-compatible API).
  (PR #4009)

• Added DTMF input event support to the Daily transport. Incoming DTMF tones are now received via Daily's on_dtmf_event callback and pushed into the pipeline as InputDTMFFrame, enabling bots to react to keypad presses from phone callers.
  (PR #4047)

• Added WakePhraseUserTurnStartStrategy for triggering user turns based on wake phrases, with support for single_activation mode. Deprecates WakeCheckFilter.
  (PR #4064)

• Added default_user_turn_start_strategies() and default_user_turn_stop_strategies() helper functions for composing custom strategy lists.
  (PR #4064)

Changed

• Changed tool result JSON serialization to use ensure_ascii=False, preserving UTF-8 characters instead of escaping them. This reduces context size and token usage for non-English languages.
  (PR #3457)

• OpenAIRealtimeSTTService's noise_reduction parameter is now part of OpenAIRealtimeSTTSettings, making it runtime-updatable via STTUpdateSettingsFrame. The direct noise_reduction init argument is deprecated as of 0.0.106.
  (PR #3991)

• Updated sarvamai dependency from 0.1.26a2 (alpha) to 0.1.26 (stable release).
  (PR #3997)

• SimliVideoService now extends AIService instead of FrameProcessor, aligning it with the HeyGen and Tavus video services. It supports SimliVideoService.Settings(...) for configuration and uses start()/stop()/cancel() lifecycle methods. Existing constructor usage (api_key, face_id, etc.) remains unchanged.
  (PR #4001)

• Update pipecat-ai-small-webrtc-prebuilt to 2.4.0.
  (PR #4023)

• Nova Sonic assistant text transcripts are now delivered in real-time using speculative text events instead of delayed final text events. Previously, assistant text only arrived after all audio had finished playing, causing laggy transcripts in client UIs. Speculative text arrives before each audio chunk, providing text synchronized with what the bot is saying. This also simplifies the internal text handling by removing the interruption re-push hack and assistant text buffer.
  (PR #4042)

• Updated daily-python dependency to 0.25.0.
  (PR #4047)

• Added enable_dialout parameter to configure() in pipecat.runner.daily to support dial-out rooms. Also narrowed misleading Optional type hints and deduplicated token expiry calculation.
  (PR #4048)

• Extended ProcessFrameResult to stop strategies, allowing a stop strategy to short-circuit evaluation of subsequent strategies by returning STOP.
  (PR #4064)

• GradiumSTTService now takes both an encoding and sample_rate constructor argument which is assmebled in the class to form the input_format. PCM accepts 8000, 16000, and 24000 Hz sample rates.
  (PR #4066)

• Improved GradiumSTTService transcription accuracy by reworking how text fragments are accumulated and finalized. Previously, trailing words could be dropped when the server's flushed response arrived before all text tokens were delivered. The service now uses a short aggregation delay after flush to capture trailing tokens, producing complete utterances.
  (PR #4066)

Deprecated

• SimliVideoService.InputParams is deprecated. Use the direct constructor parameters max_session_length, max_idle_time, and enable_logging instead.
  (PR #4001)

• Deprecated LocalSmartTurnAnalyzerV2 and LocalCoreMLSmartTurnAnalyzer. Use LocalSmartTurnAnalyzerV3 instead. Instantiating these analyzers will now emit a DeprecationWarning.
  (PR #4012)

• Deprecated WakeCheckFilter in favor of WakePhraseUserTurnStartStrategy.
  (PR #4064)

Fixed

• Fixed an issue where the default model for OpenAILLMService and AzureLLMService was mistakenly reverted to gpt-4o. The defaults are now restored to gpt-4.1.
  (PR #4000)

• Fixed a race condition where EndTaskFrame could cause the pipeline to shut down before in-flight frames (e.g. LLM function call responses) finished processing. EndTaskFrame and StopTaskFrame now flow through the pipeline as ControlFrames, ensuring all pending work is flushed before shutdown begins. CancelTaskFrame and InterruptionTaskFrame remain immediate (SystemFrame).
  (PR #4006)

• Fixed ParallelPipeline dropping or misordering frames during lifecycle synchronization. Buffered frames are now flushed in the correct order relative to synchronization frames (StartFrame goes first, EndFrame/CancelFrame go after), and frames added to the buffer during flush are also drained.
  (PR #4007)

• Fixed TTSService potentially canceling in-flight audio during shutdown. The stop sequence now waits for all queued audio contexts to finish processing before canceling the stop frame task.
  (PR #4007)

• Fixed Language enum values (e.g. Language.ES) not being converted to service-specific codes when passed via settings=Service.Settings(language=Language.ES) at init time. This caused API errors (e.g. 400 from Rime) because the raw enum was sent instead of the expected language code (e.g. "spa"). Runtime updates via UpdateSettingsFrame were unaffected. The fix centralizes conversion in the base TTSService and STTService classes so all services handle this consistently.
  (PR #4024)

• Fixed DeepgramSTTService ignoring the base_url scheme when using ws:// or http://. Previously these were silently overwritten with wss:// / https://, breaking air-gapped or private deployments that don't use TLS. All scheme choices (wss://, https://, ws://, http://, or bare hostname) are now respected.
  (PR #4026)

• Fixed LLMSwitcher.register_function() and register_direct_function() not accepting or forwarding the timeout_secs parameter.
  (PR #4037)

• Fixed empty user transcriptions in Nova Sonic causing spurious interruptions. Previously, an empty transcription could trigger an interruption of the assistant's response even though the user hadn't actually spoken.
  (PR #4042)

• Fixed SonioxSTTService and OpenAIRealtimeSTTService crash when language parameters contain plain strings instead of Language enum values.
  (PR #4046)

• Fixed premature user turn stops caused by late transcriptions arriving between turns. A stale transcript from the previous turn could persist into the next turn and trigger a stop before the current turn's real transcript arrived. Stop strategies are now reset at both turn start and turn stop to prevent state from leaking across turn boundaries.
  (PR #4057)

• Fixed raw language strings like "de-DE" silently failing when passed to TTS/STT services (e.g. ElevenLabs producing no audio). Raw strings now go through the same Language enum resolution as enum values, so regional codes like "de-DE" are properly converted to service-expected formats like "de". Unrecognized strings log a warning instead of failing silently.
  (PR #4058)

• Fixed Deepgram STT list-type settings (keyterm, keywords, search, redact, replace) being stringified instead of passed as lists to the SDK, which caused them to be sent as literal strings (e.g. "['pipecat']") in the nWebSocket query params.
  (PR #4063)

• Fixed MinWordsUserTurnStartStrategy including text below the word threshold in the output by resetting aggregation when the minimum word count is not met.
  (PR #4064)

• Fixed audio overlap and potential dropped TTS content when multiple assistant turns occur in quick succession. TTSService now flushes remaining text before pausing frame processing on LLMFullResponseEndFrame/EndFrame, instead of pausing first.
  (PR #4071)

Security

• Bumped PyJWT minimum version from 2.10.1 to 2.12.0 in the livekit extra to address CVE-2026-32597 (GHSA-752w-5fwx-jx9f), where PyJWT <= 2.11.0 accepted unknown crit header extensions.
  (PR #4035)
