AI Summary

Improves the stability and performance of the PocketTTS engine by implementing a persistent worker thread and optimizing short-text streaming to prevent memory retention issues on Windows/Torch.

Key Highlights

  • Reworked `PocketTTSEngine` to run synthesis through a persistent worker thread
  • Patch for short-text streaming to decode serially
  • New streaming controls: `streaming`, `max_tokens`, and `frames_after_eos`
  • Support for cached voice states via `PocketTTSVoice`

New Features

  • Support for custom PocketTTS model configs via `model_config`
  • Optional voice-state caching via `voice_cache_dir` and `cache_voice_states`
  • Improved audio conversion, queueing, and duration tracking
  • Dependency updates including `pocket-tts>=2.1.0`

Full Release Notes

# RealtimeTTS v0.7.2

### Improvements

* Reworked `PocketTTSEngine` to run synthesis through a persistent worker thread.
* Patched PocketTTS short-text streaming to decode serially, avoiding Windows/Torch CPU memory retention during repeated short generations.
* Added PocketTTS streaming controls: `streaming`, `max_tokens`, and `frames_after_eos`.
* Added support for custom PocketTTS model configs via `model_config`.
* Added support for cached voice states through `PocketTTSVoice(state_path=...)`.
* Added optional voice-state caching through `voice_cache_dir` and `cache_voice_states`.
* Improved PocketTTS audio conversion, queueing, duration tracking, and shutdown cleanup.

### Packaging

* Bumped package version to `0.7.2`.
* Set the PocketTTS dependency to `pocket-tts>=2.1.0`.
* Refreshed explicit dependency versions, including `stream2sentence`, `openai`, `elevenlabs`, `edge-tts`, `requests`, `cartesia`, `camb-sdk`, `omnivoice`, and `typecast-python`.
