AI Lip Sync
Make any face speak.
King AI's AI Lip Sync animates photos, characters, and video clips to speak any audio with natural mouth movement and expression. Write a script, pick a voice, and your image starts talking — in any of 31 languages.
Highlights
Natural speech, not puppet mouths.
Modern lip-sync models animate the whole face — jaw, cheeks, eyes, and micro-expressions — so the result reads as a real performance.
Talking photos
Turn any portrait — real, painted, or AI-generated — into a speaking video.
Re-dub video
Swap the dialogue in an existing clip and the mouth re-animates to match.
Any language
Phoneme-accurate sync across all 31 supported languages.
Full-face animation
Blinks, brows, and head motion follow the speech for a lifelike delivery.

Deep dive
Why it looks real.
Modern lip sync is a full facial performance, not a mouth overlay.
Phonemes
Mouth shapes that match the sound
The model maps every phoneme in the audio to the correct viseme — lips, tongue, and jaw — at the exact millisecond it's spoken.

Performance
The whole face acts
Blinks, eyebrow raises, and micro head motion follow the rhythm and emotion of the audio, so the delivery reads as a real performance.
- Expression follows the audio's emotion
- Natural blinks and head motion

FAQ
AI lip sync, answered.
What is AI lip sync?
AI lip sync analyses an audio track and animates a face — in a photo, illustration, or video — so the mouth movements match the speech naturally, including visemes, jaw movement, and facial expression.
Can I make a photo talk?
Yes. Upload any portrait — a photo, painting, or AI-generated character — add a voiceover or recording, and King AI animates it into a natural talking video.
Does it work with AI-generated voices?
Yes, and that's the magic combo: write a script, generate a voice with the AI Voice Generator, and lip-sync it onto any face in one flow.
Can I lip-sync an existing video?
Yes. Replace or re-dub the speech in a video clip and the mouth movement is re-animated to match the new audio — useful for translations and fixing takes.
Which languages work with lip sync?
All 31 supported languages. The animation follows the actual phonemes of the audio, so any language syncs correctly.
