# Stop speaking text during a call

> Halt active text-to-speech playback on a Vobiz call - interrupt looping messages on DTMF input or when an agent joins, without affecting the call session.

```http theme={null}
DELETE https://api.vobiz.ai/api/v1/Account/{auth_id}/Call/{call_uuid}/Speak/
```

Stop text-to-speech playback currently active on a call. Useful for ending looping messages when a user makes a selection, stopping announcements when an agent becomes available, or interrupting speech based on DTMF input.

<Note>
  If no text-to-speech is currently playing, this endpoint returns success without performing any action.
</Note>

```

## Response

```text 204 No Content theme={null}
HTTP Status Code: 204

## Common use cases

* Stop looping queue messages when an agent answers.
* End IVR menu announcements when a user presses a DTMF key.
* Interrupt speech when transferring to a live agent.
* Stop welcome messages when a call is answered.

<Tip>
