pipecat-ai 0.0.78

v0.0.78

on Python PyPI

Added

• Added enable_emulated_vad_interruptions to LLMUserAggregatorParams. When user speech is emulated (e.g. when a transcription is received but VAD doesn't detect speech), this parameter controls whether the emulated speech can interrupt the bot. Default is False (emulated speech is ignored while the bot is speaking).

• Added new handle_sigint and handle_sigterm to RunnerArguments. This allows applications to know what settings they should use for the environment they are running on. Also, added pipeline_idle_timeout_secs to be able to control the PipelineTask idle timeout.

• Added processor field to ErrorFrame to indicate FrameProcessor that generated the error.

• Added new language support for AWSTranscribeSTTService. All languages supporting streaming data input are now supported: https://docs.aws.amazon.com/transcribe/latest/dg/supported-languages.html

• Added support for Simli Trinity Avatars. A new is_trinity_avatar parameter has been introduced to specify whether the provided faceId corresponds to a Trinity avatar, which is required for optimal Trinity avatar performance.

• The development runner how handles custom body data for DailyTransport. The body data is passed to the Pipecat client. You can POST to the /start endpoint with a request body of:

  {
      "createDailyRoom": true,
      "dailyRoomProperties": { "start_video_off": true },
      "body": { "custom_data": "value" }
  }
  

  The body information is parsed and used in the application. The dailyRoomProperties are currently not handled.

• Added detailed latency logging to UserBotLatencyLogObserver, capturing average response time between user stop and bot start, as well as minimum and maximum response latency.

• Added Chinese, Japanese, Korean word timestamp support to CartesiaTTSService.

• Added region parameter to GladiaSTTService. Accepted values: eu-west (default), us-west.

Changed

• System frames are now queued. Before, system frames could be generated from any task and would not guarantee any order which was causing undesired behavior. Also, it was possible to get into some rare recursion issues because of the way system frames were executed (they were executed in-place, meaning calling push_frame() would finish after the system frame traversed all the pipeline). This makes system frames more deterministic.

• Changed the default model for both ElevenLabsTTSService and ElevenLabsHttpTTSService to eleven_turbo_v2_5. The rationale for this change is that the Turbo v2.5 model exhibits the most stable voice quality along with very low latency TTFB; latencies are on par with the Flash v2.5 model. Also, the Turbo v2.5 model outputs word/timestamp alignment data with correct spacing.

• The development runners /connect and /start endpoint now both return dailyRoom and dailyToken in place of the previous room_url and token.

• Updated the pipecat.runner.daily utility to only a take DAILY_API_URL and DAILY_SAMPLE_ROOM_URL environment variables instead of argparsing -u and -k, respectively.

• Updated daily-python to 0.19.6.

• Changed TavusVideoService to send audio or video frames only after the transport is ready, preventing warning messages at startup.

• The development runner now strips any provided protocol (e.g. https://) from the proxy address and issues a warning. It also strips trailing /.

Deprecated

• In the pipecat.runner.daily, the configure_with_args() function is deprecated. Use the configure() function instead.

• The development runner's /connect endpoint is deprecated and will be removed in a future version. Use the /start endpoint in its place. In the meantime, both endpoints work and deliver equivalent functionality.

Fixed

• Fixed a DailyTransport issue that would result in an unhandled concurrent.futures.CancelledError when a future is cancelled.

• Fixed a RivaSTTService issue that would result in an unhandled concurrent.futures.CancelledError when a future is cancelled when reading from the audio chunks from the incoming audio stream.

• Fixed an issue in the BaseOutputTransport, mainly reproducible with FastAPIWebsocketOutputTransport when the audio mixer was enabled, where the loop could consume 100% CPU by continuously returning without delay, preventing other asyncio tasks (such as cancellation or shutdown signals) from being processed.

• Fixed an issue where BotStartedSpeakingFrame and BotStoppedSpeakingFrame were not emitted when using TavusVideoService or HeyGenVideoService.

• Fixed an issue in LiveKitTransport where empty AudioRawFrames were pushed down the pipeline. This resulted in warnings by the STT processor.

• Fixed PiperTTSService to send text as a JSON object in the request body,
  resolving compatibility with Piper's HTTP API.

• Fixed an issue with the TavusVideoService where an error was thrown due to missing transcription callbacks.

• Fixed an issue in SpeechmaticsSTTService where the user_id was set to None when diarization is not enabled.

Performance

• Fixed an issue in TaskObserver (a proxy to all observers) that was degrading global performance.

Other

• Added 07aa-interruptible-soniox.py, 07ab-interruptible-inworld-http.py, 07ac-interruptible-asyncai.py and 07ac-interruptible-asyncai-http.py release evals.
