What InfiniteTalk AI is

InfiniteTalk AI drives a character from audio. Given a source image or video and a voice track, it produces a talking person with lip movement, expression and body motion, aiming to keep the subject's identity stable.

The site emphasizes sparse-frame and long-sequence generation, which suits longer talking clips rather than a single shot.
