What is Lip Sync?
Lip sync is the process of matching a speaker’s lip movements to the words they are saying. In videos, when the lip movement matches the audio perfectly, it feels natural — as if the person or character is truly speaking. Any mismatch makes the scene look strange and breaks immersion.
Why AI Lip Sync?
Traditionally, lip syncing required manual animation or expensive motion capture equipment — both time-consuming and costly.
AI changes the game: it can automatically analyze speech and adjust the lip movement in minutes, saving hours of editing.
Accurate lip sync makes your content:
- More immersive — Audiences feel like they’re watching real conversations.
- More persuasive — Perfect alignment between sight and sound builds trust.
- More global — AI can sync lips to match different languages, so your video can “speak” to the world.
