Lip sync 1 is an AI lip sync generator that synchronizes mouth movements in video to match an audio track. It uses artificial intelligence to align speech timing and mouth shapes for natural talking results.

What files can I use for AI lip syncing?

You can upload a video clip with a visible face and add an audio file or voice track. The tool analyzes the face area and applies machine-learning lip sync to match the spoken words.
