Lipsync Re-sync any video's mouth to any audio with AI

源视频 *

Use a clip where the person is already talking, face-on, mouth visible. Sync Lipsync 2 and Pro cannot open a shut mouth or still face — they only retarget existing speech. For a still portrait, use the Talking Head generator instead.

免费 AI Lipsync Generator

Take an existing video clip of a person and a separate audio track, and generate a new video where their mouth moves in sync with the audio. Perfect for dubbing, language localization, character voiceovers, and editing accurate dialogue into existing footage.

Perfect For

Content creators dubbing videos into new languages, marketers localizing brand campaigns, educators producing multi-language course material, indie filmmakers editing dialogue without reshoots, podcasters turning audio into talking-head video, and anyone who wants to put new words in an existing speaker's mouth.

Key Features

Three production-grade lipsync engines (PixVerse, Sync Lipsync 2, Sync Lipsync 2 Pro) at different price points, supports any video clip with a clearly visible face, accepts MP3/WAV/M4A audio, multiple sync modes (cut off, loop, bounce, silence, remap) for handling clips of mismatched length, optional active-speaker detection for multi-person scenes, and adjustable expressiveness for natural-looking results.
