AI lip sync generator

It takes a face and an audio track and redraws the mouth so it forms the words being spoken. The rest of the shot is left alone, so the performance, the head movement, and the lighting all survive. What changes is the part that would otherwise give away that the voice was added later.

Yes. A single portrait is enough. A still has no motion to resync, so it is routed to a video model that brings the face to life and matches the mouth to your track, which is why a photograph that never moved starts speaking. It is the fastest way to get a talking presenter out of an image you already have, without filming anyone.

A recording of your own voice, a generated voiceover, or an existing dialogue track. If you do not have the audio yet, generate it first with text to speech and bring it straight here. Clean audio with one clear speaker syncs more accurately than a noisy room recording with overlapping voices.

Yes. The model matches mouth shapes to the sounds in the track, so it follows whatever language the audio is in. That is what makes it useful after translation: a presenter recorded in English can be re-voiced in Spanish or Japanese and still look like they said it.

Generation happens in short segments, so long pieces are handled by syncing section by section and assembling the results. For a talking-head video that is rarely a limitation, because natural break points fall between sentences anyway.

Yes. The source stays in charge of identity, so features, skin, and lighting hold. Resyncing a clip you already have changes the mouth and leaves the rest of the performance alone. Starting from a single photo is a little different: the face is held, but you also get natural head movement and gesture, because a still has to be given motion before it can speak. Give it a clear, well-lit, front-facing source either way.

Yes. Save the setup as a Workflow and push each new audio track through it. A weekly explainer or a set of localised versions comes out consistent instead of being reassembled by hand every time.
