Is it possible to change the voice utilized on the warm transfer functionality? I want PT-PT and the current voice is very bad at it

Yes, you can change the voice used for the warm transfer assistant by specifying the

voice

property in your assistant's configuration. For PT-PT, set the provider and the desired Portuguese (Portugal) voice ID as shown below:

json
"model": {
  "provider": "azure",
  "voice": { "provider": "azure", "voiceId": "pt-PT-FernandaNeural" }
}

Replace

pt-PT-FernandaNeural

with your preferred PT-PT voice ID if needed. Test different voices for best quality.
