Generate Audio Prompts using AI Text-to-Speech

With AI Text-to-Speech (TTS), you type the wording you want and the system produces a natural-sounding audio prompt for you. There is no need to record anything or upload a file. This page shows where TTS prompts can be used and walks through creating one.

Enable AI Text-to-Speech for your account. The Text-to-Speech option only appears in the settings below once the feature is switched on.

Wherever a feature accepts a voice prompt or greeting, you can generate it with Text-to-Speech. The following areas support it:
