Sonic

Sonic is an open research project that animates portraits with audio. You give it a face photo and an audio clip, and it makes the face speak with synced lips. It comes from a CVPR 2025 paper on audio-driven portrait animation. It suits researchers and developers working with talking-head video. The code is free for non-commercial use under a Creative Commons license. Check the GitHub repo for the current code, demos, and usage steps before you start. CVPR is a top computer vision conference where the paper was shown.

Key Features

1. Audio-Driven Animation

The model watches the whole audio clip to plan motion. Faces move in time with the sound.

2. Precise Lip-Sync

Mouth movements match the spoken words closely. This makes the result look like real speech.

3. Portrait Input

You start with a single face photo. The system brings that still face to life.

4. Research Code

The official code is open on GitHub. It is free for non-commercial use under CC BY-NC-SA 4.0.
