# What is Lip Sync?

Matching a speaker's mouth movements to an audio track. AI lip sync reshapes the mouth in existing or generated footage so a new line, translation or voiceover looks spoken on camera.

## In real work

When the offer changed from 20 to 30 percent off, the editor used lip sync to fit the new line to the spokesperson's mouth, with her written approval on file.
