Returns immediately, streaming generation. By default, calls queue and play sequentially (including across turns). Pass `interrupt=True` to abort current playback and clear the queue first. Pass `language=` (`french` / `english`) to switch model on the fly. |\n| `stop_speaking()` | Stop current playback, drop queue, cancel in-flight generation. Use for explicit \"mute\" requests. For mid-turn interruption + new speech, use `speak(..., interrupt=True)` instead. |\n| `status()` | Report loaded languages, queue depths, sample rate, last error. |\n\n## Configuration\n\nThe default language is set via `--language` (CLI) or `KYUTAI_TTS_LANGUAGE`\n(env var).
