AI Lip Sync Video Generator

Lip sync AI is voice-driven facial animation that matches mouth movements to audio dialogue frame-by-frame. It extracts phoneme timing — mapping consonants, vowels, and pauses to lip shapes. Unlike manual dubbing costing $500-15,000, it delivers results in under 60 seconds.

Upload your video or portrait photo with the audio track. Select target language if dubbing, then click generate. Synced video ready in under 60 seconds with frame-accurate mouth movements.

94% of viewers cannot distinguish AI-synced from manually dubbed results in blind tests. The system processes upper and lower facial regions separately — preserving eye movements, eyebrow raises, and head tilts that other tools freeze.

40+ languages including English, Spanish, Mandarin, French, German, Japanese, Korean, Portuguese, Arabic, and Hindi. Each uses native phoneme models for language-specific mouth shapes.

Synthesia and HeyGen generate avatar-only videos — digital presenters from scratch, but cannot dub real-person footage. Lip Sync AI works with both real video and photos: upload footage, get synced results with original expressions preserved. Processing under 60 seconds.

Yes. Multi-speaker detection tracks different faces, assigns voice tracks to each speaker, and applies independent processing. Each character's mouth movements match their dialogue independently.
