AI Lip Sync

Lip sync AI changes what the person in a video appears to say. You give it two things: a video with a face, and an audio track with new speech or singing. The model listens to the audio, works out the mouth shape for every sound, and redraws the lips, teeth and jaw in each frame so they move with the new words. Everything else - the face, the head movement, the hair, the clothes and the background - stays as it was filmed, and the new audio replaces the original sound. That makes it a quick way to dub a video into another language without the mouth and the voice drifting apart, to fix a line after the shoot instead of filming again, to turn one recording into several versions of an ad, or to make a clip sing along to a song. Because the model follows the sound rather than the text, it works with any language and with singing as well as speech. There are two versions: Standard is faster and cheaper and returns a slightly smaller video, while Pro keeps the original resolution and gives sharper lips. Everything runs in the browser, on a phone or a computer.
