Lip-sync models reshape the mouth and jaw of a video face to fit new speech, used for dubbing into other languages and for AI presenters. Quality depends on natural mouth shapes and exact timing; visible mismatch breaks the illusion fast.

AI for Video: A Complete Guide to Intelligence in Video Products: From Models and Inference to Computer Vision, Speech, Search, and Generative Video
Lip-sync breaks the illusion of an AI presenter the moment mouth shapes drift from the audio. This volume covers lip-sync models in its generative video section: talking-head and avatar generation, AI dubbing with TTS and voice cloning, and choosing between closed APIs and open models. Written by Nikolay Sapunov, CEO at Fora Soft.
