Voice Cloning - telli Documentation

Voice cloning lets you give your agent a custom voice (your own, a colleague’s, or a professional voice actor’s), so the agent sounds exactly the way you want on every call.

Three ways to get a custom voice

Option	When to use
Clone in-app	The fastest path. Record or upload your own audio sample and let telli build a voice from it.
Import from a provider	If you already have a voice configured with a provider like ElevenLabs or Cartesia, import it directly.
Professional voice clone	Best quality. Submit a longer recording and let our team produce a high-fidelity clone for you.

For premium-quality voice cloning (especially if the voice will be used at scale), follow the Professional Voice Cloning process in the cookbook below. It walks you through the recording requirements and submission steps.

Professional Voice Cloning

Give your agent a custom voice by cloning a professional voice for use in your calls.
