- Generate. The model maps every phoneme to natural mouth, jaw and head motion.

What separates good lip sync from uncanny lip sync
Cheap tools animate only the lips, which reads as fake within seconds. Convincing results need the whole face to respond to the audio: jaw weight, cheek motion, blinks and small head movements timed to the speech rhythm. That is what the InfiniteTalk models are built for, and why they also hold up on trending video formats where the character talks straight to camera.

Can AI lip sync work in any language?
Yes. The lip-sync is driven by the audio itself, so it works across languages. Combined with voice cloning, you can localize one video into many languages with matching mouth movement.
How do I lip sync a photo to audio?
Upload the photo, add the audio or type a script with a chosen voice, and generate. Percify animates the face so the mouth, jaw and expressions follow the audio naturally.
Why do some AI lip sync videos look off?
Common causes are low-quality source photos, noisy audio, or models that only animate the lips and not the surrounding face. Using a clear frontal portrait, clean audio, and a model that animates full facial motion, like InfiniteTalk, fixes most artifacts.
