Talking Avatar

Talking Avatar Open Source · Free · MIT

Open-source 3D avatar demo

Everything runs in your browser: the 1 MB model listens to the audio and moves the 3D avatar's lips. Pick a voice, play your own file, or talk into your microphone.

Realistic Avatars and Open Source

The two versions of Talking Avatar

Talking Avatar comes in two separate versions. Talking Avatar Realistic Avatars is a hosted, paid service of ready-made photorealistic avatars, rendered on our servers and streamed to your page over WebRTC or into your LiveKit room, for $0.02 a minute. Talking Avatar Open Source is a free, MIT-licensed 3D talking avatar for the browser: it renders your own 3D .glb avatar and animates its face from any audio (lip sync from a 1 MB model, plus natural blinks and brows), with no server, account or API key, free for commercial and noncommercial use. Both are driven by your own voice agent: OpenAI Realtime, LiveKit, Pipecat or any TTS.
