v0.0.91

Added

• It is now possible to start a bot from the /start endpoint when using the runner Daily's transport. This follows the Pipecat Cloud format with createDailyRoom and body fields in the POST request body.

• Added an ellipsis character (…) to the end of sentence detection in the string utils.

• Expanded support for universal LLMContext to AWSNovaSonicLLMService. As a reminder, the context-setup pattern when using LLMContext is:

  context = LLMContext(messages, tools)
  context_aggregator = LLMContextAggregatorPair(context)

  (Note that even though AWSNovaSonicLLMService now supports the universal LLMContext, it is not meant to be swapped out for another LLM service at runtime.)

  Worth noting: whether or not you use the new context-setup pattern with AWSNovaSonicLLMService, some types have changed under the hood:

  ## BEFORE:
  
  # Context aggregator type
  context_aggregator: AWSNovaSonicContextAggregatorPair
  
  # Context frame type
  frame: OpenAILLMContextFrame
  
  # Context type
  context: AWSNovaSonicLLMContext
  # or
  context: OpenAILLMContext
  
  ## AFTER:
  
  # Context aggregator type
  context_aggregator: LLMContextAggregatorPair
  
  # Context frame type
  frame: LLMContextFrame
  
  # Context type
  context: LLMContext

• Added support for bulbul:v3 model in SarvamTTSService and SarvamHttpTTSService.

• Added keyterms_prompt parameter to AssemblyAIConnectionParams.

• Added speech_model parameter to AssemblyAIConnectionParams to access the multilingual model.

• Added support for trickle ICE to the SmallWebRTCTransport.

• Added support for updating OpenAITTSService settings (instructions and speed) at runtime via TTSUpdateSettingsFrame.

• Added --whatsapp flag to runner to better surface WhatsApp transport logs.

• Added on_connected and on_disconnected events to TTS and STT websocket-based services.

• Added an aggregate_sentences arg in ElevenLabsHttpTTSService, where the default value is True.

• Added a room_properties arg to the Daily runner's configure() method, allowing DailyRoomProperties to be provided.

• The runner --folder argument now supports downloading files from subdirectories.

Changed

• RunnerArguments now include the body field, so there's no need to add it to subclasses. Also, all RunnerArguments fields are now keyword-only.

• CartesiaSTTService now inherits from WebsocketSTTService.

• Package upgrades:

  • daily-python upgraded to 0.20.0.
  • openai upgraded to support up to 2.x.x.
  • openpipe upgraded to support up to 5.x.x.

• SpeechmaticsSTTService updated dependencies for speechmatics-rt>=0.5.0.

Deprecated

• The send_transcription_frames argument to AWSNovaSonicLLMService is deprecated. Transcription frames are now always sent. They go upstream, to be handled by the user context aggregator. See "Added" section for details.

• Types in pipecat.services.aws.nova_sonic.context have been deprecated due to changes to support LLMContext. See "Changed" section for details.

Fixed

• Fixed an issue where the RTVIProcessor was sending duplicate UserStartedSpeakingFrame and UserStoppedSpeakingFrame messages.

• Fixed an issue in AWSBedrockLLMService where both temperature and top_p were always sent together, causing conflicts with models like Claude Sonnet 4.5 that don't allow both parameters simultaneously. The service now only includes inference parameters that are explicitly set, and InputParams defaults have been changed to None to rely on AWS Bedrock's built-in model defaults.

• Fixed an issue in RivaSegmentedSTTService where a runtime error occurred due to a mismatch in the _handle_transcription method's signature.

• Fixed multiple pipeline task cancellation issues. asyncio.CancelledError is now handled properly in PipelineTask making it possible to cancel an asyncio task that it's executing a PipelineRunner cleanly. Also, PipelineTask.cancel() does not block anymore waiting for the CancelFrame to reach the end of the pipeline (going back to the behavior in < 0.0.83).

• Fixed an issue in ElevenLabsTTSService and ElevenLabsHttpTTSService where the Flash models would split words, resulting in a space being inserted between words.

• Fixed an issue where audio filters' stop() would not be called when using CancelFrame.

• Fixed an issue in ElevenLabsHttpTTSService, where apply_text_normalization was incorrectly set as a query parameter. It's now being added as a request parameter.

• Fixed an issue where RimeHttpTTSService and PiperTTSService could generate incorrectly 16-bit aligned audio frames, potentially leading to internal errors or static audio.

• Fixed an issue in SpeechmaticsSTTService where AdditionalVocabEntry items needed to have sounds_like for the session to start.

Other

• Added foundational example 47-sentry-metrics.py, demonstrating how to use the SentryMetrics processor.

• Added foundational example 14x-function-calling-openpipe.py.
