What's New

Switched default TTS to Deepgram Aura and fixed pause-mode audio drop bug

Improvements

  • Default TTS provider changed to Deepgram Aura for lower latency.
  • Reduced time-to-first-audio and PSTN call gaps.

Bug Fixes

  • Pause-mode barge-in no longer drops bot audio after arbitration resolutions.

Upgrade Notes

The pipecat-bot-py example now uses Deepgram Aura by default. If you need the previous OpenAI behavior, set `BOT_TTS_PROVIDER=openai` and `BOT_TTS_MODEL=tts-1`.
