Configure Google Cloud TTS Custom Voices

Prerequisites:

Voice name, location, region, model, and language provided by Google Cloud. For more information, see Create custom voices with Google Cloud Text-to-Speech and Custom Voice quickstart in the Google Cloud Text-to-Speech documentation.

To use custom voices, follow these steps to update the Google Cloud TTS integration.

Click Admin.
Under Integrations, click Integrations.
Click the Google Cloud Text-to-Speech integration.
Click the Configuration tab and then click Advanced.

Copy the JSON example below and paste it into the Advanced Configuration field. This example configuration uses two custom Google TTS voices. If you only use one voice, then you can omit the section after "en-US" }.

     "customVoices": [
          {
               "displayName": "My-Custom-Voices-1",
                "model": "projects/112345678901234/locations/us-central1/models/XXXXXXX-XXXX-XXXX-XXXX-XXXXXX",
                "language": "en-US"
          },
          {
               "displayName": "My-Custom-Voices-2",
               "model": "projects/12345678901234/locations/us-central1/models/XXXXXXX-XXXX-XXXX-XXXX-XXXXXX",
