TTS Models
An overview of Text-to-Speech providers and models you can use with the Voice Agent API.
By default Deepgram Text-to-Speech will be used with the Voice Agent API, but if you opt to use another provider’s TTS model with your Agent, you can do so by applying the following settings.
You can set your Text-to-Speech model in the Settings Message for your Voice Agent. See the docs for more information.
