Google text-to-speech

Google is one of the text-to-speech services you can select for a bot connection, while creating the connection or later on its Settings tab.

To use Google for text-to-speech:

  1. From the 'Text-to-speech provider' drop-down list, select Google.

  2. From the 'Model' drop-down list, select the model, for example Gemini 2.5 Pro.

  3. From the 'Voice name' drop-down list, select the voice the caller hears.

  4. Click Create.

If text-to-speech times out

If the text-to-speech service does not respond in time, raise ttsConnectionTimeoutMS above 5000 ms. Set it in the JSON editor on the bot connection's Advanced tab. See Manage bot connections.

{
    "ttsProviderParams": {
        "ttsConnectionTimeoutMS": 6000
    }
}
