on GitHub

Added

• Added audio_passthrough parameter to STTService. If enabled it allows audio frames to be pushed downstream in case other processors need them.

• Added input parameter options for PlayHTTTSService and PlayHTHttpTTSService.

Changed

• Changed DeepgramSTTService model to nova-2-general.

• Moved SileroVAD audio processor to processors.audio.vad.

• Module utils.audio is now audio.utils. A new resample_audio function has been added.

• PlayHTTTSService now uses PlayHT websockets instead of HTTP requests.

• The previous PlayHTTTSService HTTP implementation is now PlayHTHttpTTSService.

• PlayHTTTSService and PlayHTHttpTTSService now use a voice_engine of PlayHT3.0-mini, which allows for multi-lingual support.

• Renamed OpenAILLMServiceRealtimeBeta to OpenAIRealtimeBetaLLMService to match other services.

Deprecated

• LLMUserResponseAggregator and LLMAssistantResponseAggregator are mostly deprecated, use OpenAILLMContext instead.

• The vad package is now deprecated and audio.vad should be used instead. The avd package will get removed in a future release.

Fixed

• Fixed an issue that would cause an error if no VAD analyzer was passed to LiveKitTransport params.

• Fixed SileroVAD processor to support interruptions properly.

Other

• Added examples/foundational/07-interruptible-vad.py. This is the same as 07-interruptible.py but using the SileroVAD processor instead of passing the VADAnalyzer in the transport.
