Quick answer
What is lip sync AI?
Lip sync AI, or an AI lip sync generator, redraws a speaker's mouth and lower face so the lips match a new audio track, which makes dubbing or a talking photo believable. In Kenerate AI's Avatar Talk you upload a video and an audio file and pick one of 7 engines, with clips up to 10 minutes and two-speaker support. It works on the free plan.

Real demo
Same clip, three versions
Switch versions and turn the sound on. The Spanish voice alone doesn't match the lips — lip sync fixes that.
- Original (English). A Wan 3 clip with an English line.
- Spanish dub. ElevenLabs dubbing — new language, same lips.
- Spanish + lip sync. VEED Lipsync 2 redraws the mouth to the Spanish audio.
All three are unedited outputs of Kenerate's tools.

Tips
Lip sync that looks real
From VEED's, Kling's and Sync Labs' guides and our tests.
Show the whole face — hands or mics over the mouth break it.
Front or three-quarter angles work best.
Match the audio length to the video, or pick a sync mode.
Use clean speech without music under it.
Two people talking? Use an InfiniteTalk Duo engine.
Only lip sync people who agreed to it.

FAQ
AI Lip Sync Generator questions
8 questions
What is AI lip sync?
AI that redraws a speaker's mouth and lower face so the lips match a new audio track — for dubbing, dialogue fixes or music.
Link to this answerHow is lip sync different from dubbing?
Dubbing replaces the voice with another language; lip sync changes the mouth to match audio. The demo shows both: the Spanish dub alone, then the dub with lip sync.
Link to this answerWhat is a lip dub?
Originally a one-take music video where a crowd lip syncs to a song; today it also means AI dubbing with the lips re-synced.
Link to this answerDoes lip sync work in any language?
Yes — it follows the sounds in the audio, so any spoken language works.
Link to this answerCan I use lip sync AI online without installing anything?
Yes. Avatar Talk runs in the browser: upload the video (up to 200 MB) and the new audio (up to 50 MB), pick one of the 7 engines and generate. There is nothing to install and no GPU to set up on your side.
Link to this answerHow long can the video be?
Up to 10 minutes on InfiniteTalk, 5 minutes on VEED Lipsync 2, Sync Lipsync 3 and LatentSync, 15 seconds on React-1.
Link to this answerCan I lip sync a photo instead?
Yes, but that's a different job. Lip sync keeps an existing video's performance and only redraws the mouth; a talking photo animates a still portrait from scratch. For a picture, use Avatar Talk in photo mode (19 engines) — the Talking photo AI page shows how.
Link to this answerIs there a free AI lip sync generator?
Yes, to start: lip sync works on the free plan with the sign-up credits, so you can test a short clip on VEED Lipsync 2 or LatentSync. Longer videos, up to 10 minutes on InfiniteTalk, use one-time credit packs that never expire.

AI Lip Sync Generator, explained
How lip sync models work
The model reads the audio — ByteDance's LatentSync uses Whisper audio features — and regenerates the mouth region frame by frame to match, keeping the rest of the face and the scene untouched.
Dub, then sync
For a translated video, dub the audio first (Kenerate's dubbing tool does 33 languages), then lip sync the video to the new track. The demo on this page is exactly that pipeline.
