To close the websocket connection, you can either send an websocket Close frame, or send the optional close message.

What is the Close Message?

In real-time text-to-speech processing, there are scenarios where you may need to force the server to end the connection (or close) immediately. Deepgram supports a Close message to handle such situations.

Sending Close

To send the Close message, you need to send the following JSON message to the server:

{
    "type": "Close"
}

Close Confirmation

Upon receiving the Close message, the server will close the websocket connect and return:

Disconnected from wss://api.deepgram.com/v1/speak  
14:57:21  

1000 Normal Closure:

Connection was closed successfully.

Conclusion

In real-time text-to-speech processing, situations may arise where you need to immediately stop the server's operations. To manage this, Deepgram provides a Close message, which ensures the server halts processing and closes the connection promptly, maintaining control and responsiveness in critical scenarios.
