Lip Sync AI Frequently Asked Questions

Lip Sync AI is an AI lip sync tool that turns photos and videos into talking videos. Upload a portrait or video, add text or audio, and Lip Sync AI automatically synchronizes the person's lip and facial movements with the speech.

An AI lip sync generator creates synchronized mouth movements from an image or video and a voice or audio track. Lip Sync AI analyzes the face and speech, then generates a talking video where the lip movements match the spoken words.

AI lip sync works by analyzing both the facial features in the source media and the timing of the speech. Lip Sync AI generates matching mouth and facial movements frame by frame to create a synchronized talking video.

Generation can fail because of unsupported files, corrupted media, insufficient credits, content restrictions, or temporary processing issues. Check the file format and account balance first, then try generating the video again.

Make sure your image, video, or audio uses a supported format and stays within the current file-size and duration limits. If the upload continues to fail, try another supported file or contact support.
