Lipsync meaning

Lipsync (lip sync) is matching a mouth to a soundtrack, and a lipsync model is the AI model that does it. It takes audio plus a still photo, a video of a face or, on some models, plain text, and returns a video in which the mouth moves with the words. To try one with your own face and voice, use the AI lipsync generator.

The three input shapes behave differently. Audio plus a still photo generates the whole performance, including head movement it invented. Audio plus existing footage repaints only the mouth region and leaves your original performance intact. Text plus a face collapses the two steps, generating the voice and the mouth in one pass.

The quality ceiling is set by the face, not the audio. Frontal, evenly lit, mouth clearly visible, no hand crossing the jaw: those inputs sync cleanly. Profile angles, heavy shadow and fast head turns are where the mouth region starts to smear.

Lipsync is one component of dubbing, not a synonym for it. Dubbing also involves translation and a voice; lipsync is only the part that makes the mouth agree with whatever audio you ended up with. The table below lists the lipsync models in the Versely catalog, best lipsync model compares them by what a job costs, and lipsync a photo to audio is the editing task that turns a still into a talking clip.
