Works With Text or Audio

Type a script and the AI lip sync free tool generates the voice and syncs it to the face. Or bring your own audio file and let the generator match it to your chosen avatar.

Multiple Characters in One Project

The AI lip sync generator handles more than one voice in the same video without losing accuracy on either of them.

Tone and Delivery Control
