AI Lip Sync
Key Features of AI Lip Sync
Make any speaker say anything — in their own face.
Production-Grade Sync
PixVerse's lip-sync model is tuned for natural mouth motion and phoneme alignment across emotions and accents.
Bring Your Own Audio
Use any speech track — TTS output, voice-over recordings, translated audio, or a different language.
Identity-Preserving
Keeps the speaker's face, lighting, and head motion intact — only the mouth region is re-animated.
Per-Second Pricing
You only pay for the output video length. The credit estimate updates as soon as you upload the video.
Cross-Language Dubbing
Combine with the Video Translator to re-record dialogue in any language and re-sync the mouth in one pipeline.
Commercial-Safe Output
Outputs can be used in paid products. Inputs and outputs are not retained for training.
How to Lip-Sync a Video
Sync mouth to audio in three steps:
Upload Talking-Head Video
MP4 or MOV up to 200MB. Best with a clear front-facing face and steady lighting.
Upload Speech Audio
MP3 / WAV / M4A / AAC up to 50MB. The audio drives the new mouth motion.
Generate and Download
AI re-animates the mouth region to match the audio. Preview and download the synced MP4 when ready.
