A voice defines how your avatar sounds. LiveAvatar pairs real-time lip-synced video with natural-sounding speech, and the voice you choose shapes the entire audio experience — tone, accent, pacing, and personality. Together with a context, it is one of the building blocks of a voice agent.
Voices are used in FULL Mode only — outside it, you bring your own audio pipeline, so voice selection and configuration are handled on your side.

​
What voices are available

​
Voice library

LiveAvatar includes a library of voices spanning different languages, genders, and speaking styles. You can preview any voice before committing to it, making it easy to audition options and find the right fit.

​
Avatar-generated voices

When you create a custom avatar from video footage, LiveAvatar also generates a voice from that footage. This gives your avatar a voice that naturally matches its appearance — no extra setup needed.

​
Bring your own voice

In addition to the above, you can import voices from third-party TTS providers. This opens the door to custom-cloned voices, branded voices, or any voice available in a provider’s catalog. See Custom TTS Integration for a step-by-step guide on adding your own voice.

How to use a voice in a LiveAvatar session

LiveAvatar gives you control over how your avatar sounds when starting a session. Every avatar comes with a default voice, but you can override it with any available voice. Once you have selected a voice, you can fine-tune how it sounds at session time. The available controls depend on the underlying provider — for example, you can adjust speed, stability, style, and more. These settings are optional, and sensible defaults are applied if you skip them. For a full breakdown of available controls by provider, see the Voice Settings page.
