# Play a staged TTS utterance

`POST /legs/{id}/tts/{ttsID}/commit`

Starts playback of an utterance staged by the preflight endpoint. Returns immediately, before synthesis has necessarily finished; failure is reported asynchronously on `tts.error`, exactly as for `POST /legs/{id}/tts`. Once committed, stop playback with `DELETE /legs/{id}/play/{playbackID}` using the same `tts_id`.

## Response `200`

TTS committed; playback starts as soon as the audio is ready

- StatusResponse
  - `instance_id` string — Instance identifier
  - `status` string, required

## Other responses

- `404` — No staged TTS with that id
- `409` — Staged TTS already committed
