# Hermes Qwen3-TTS PCM streaming adapter

This optional Hermes backend plugin uses Athena's native
`/v1/audio/speech/pcm-stream` route. It starts playback while Qwen3-TTS is
still synthesizing the current sentence instead of waiting for a complete
audio file.

Install this directory as `${HERMES_HOME}/plugins/qwen3-stream`, enable the
plugin and set:

```yaml
tts:
  provider: qwen3-stream
  streaming:
    provider: qwen3-stream
```

The adapter reuses `tts.openai.base_url`, `tts.openai.api_key`, model, voice
and language unless an explicit `tts.qwen3-stream` section overrides them.
This avoids copying the Athena credential into another file.

Rollback is immediate: restore `tts.provider` and `tts.streaming.provider` to
`openai`, disable the plugin and restart the Hermes gateway.
