Sonic AI
Turn static portraits into lifelike talking faces with Sonic AI. One image one audio file endless possibilities. Sonic takes any still portrait and brings it to life using only audio. Singing speeches even full vlogs.
Overview
Sonic comes from researchers at Tencent AI Lab and Zhejiang University—groups known for Hunyuan and other avatar and animation work like RealTalk and VividTalk. These teams specialize in AI-driven video and facial animation tech.
Most tools stitch together faces with lots of visual help but Sonic flips that. It listens. It learns how you talk from your voice’s tone speed and rhythm and turns that into facial movement. It doesn’t lean on 3D motion data or cheat with overlapping clips. It borrows from the best video and audio toolkits to give you a full studio feel.
Here's how it works:
Context-Enhanced Audio Learning. It listens to big chunks of audio not just second-by-second clips so it knows the mood and pace.
Motion-Decoupled Controller. It splits face and head motion so one doesn’t mess up the other. Wanna nod a little while talking? No problem. You can even push expressions further if you want more drama.
Time-Aware Shift Fusion. Long video? No hiccups. It builds each clip while keeping a memory of what came before so everything flows. This works even for 10-minute long videos.
And it’s all one-click easy once it’s set up. No messing with keyframes or animation software.
In tests Sonic beat out other tools like SadTalker Hallo and Aniportrait in almost every metric. Better sync better emotion more natural movement. User studies showed people just liked it more especially for long clips.

The best results come when the character’s head is big and centered in the frame. Full-body shots? Not really there yet. That said it does work on videos too not just still images as long as you hook up the right nodes. Some folks are trying out ControlNet and vid2vid setups to animate multiple characters or add more advanced motion. Lip sync seems solid overall even with minimal setup which surprised a few people. One thing to keep in mind though is the licensing. The Sonic node for Comfy is MIT licensed but the original Sonic code may not be fully open source for commercial use so you might wanna double check that before using it for paid work. [ Reddit ]
