How accurate is AI lip sync compared to manual animation?

Modern AI lip sync captures natural speech cadence and mouth shapes well enough for marketing and educational content. For cinema-grade requirements, manual refinement may still be needed.

Can I use my own voiceover audio?

Yes. Upload any audio track and the system maps mouth movements to the speech patterns. This works with professional voiceovers, recorded narration, and AI-generated speech.

Does lip sync work across different languages?

Yes. The speech-motion mapping adapts to different phonetic patterns. Generate localized versions of the same character by swapping the audio track and regenerating with language-appropriate sync.

Lip Sync That Looks Natural, Not Uncanny

AI-generated characters that speak need mouths that move convincingly. Poor lip sync breaks immersion instantly and makes content look amateurish. Seedance Lab mode provides precise control over speech-to-motion mapping, producing lip sync that matches audio cadence naturally — for UGC-style content, narrator-driven explainers, and character-based series where believable speech is non-negotiable.
