Free AI Lip Sync Video Generator
Create AI lip sync videos with Morph Studio. Upload a video, add your audio or voiceover, and generate a new version where the speaker's mouth movement syncs to the uploaded audio. Replace the original video audio, create natural-looking speech sync, and download a polished lip sync video for social content, ads, explainers, voiceover edits, and creative workflows.
Sync Video Mouth Movement to Your Audio
Upload a video and add the audio you want the speaker to say. Morph Studio uses AI lip sync to match the speaker's mouth movement to your uploaded voiceover or audio track, helping you create a new lip-synced video without manual frame-by-frame editing or complex post-production work.
Replace Original Video Audio with a New Voiceover
Use Lip Sync to replace the original audio in a video with your uploaded audio file. The result is a new video where the visible speech movement follows the new audio, making it useful for voiceover edits, translated-style clips, product messages, training videos, explainers, and creator content.
Create Lip Sync Videos for Social, Ads, and Explainers
Turn existing videos into new talking clips for short-form content, ads, product explainers, tutorials, presentations, and social posts. Use Lip Sync after text-to-video generation or source video uploads, add the audio you want, generate the lip sync result, and download a ready-to-use video inside the Morph Studio workflow.
Create AI Lip Sync Videos in 3 Steps
Upload a video, add audio, and generate a synced result
Upload Your Video
Start with the video you want to edit. Use a clear talking-head, speaker, character, or presenter video so the mouth movement can be synced more naturally to the new audio.
Upload Your Audio
Add the audio or voiceover file you want to use. Lip Sync replaces the original video audio with your uploaded audio and uses it to guide the mouth movement in the generated result.
Generate and Download
Generate your AI lip sync video, review the speech timing and mouth movement, then download the final result for social content, ads, explainers, presentations, voiceover edits, or other creative workflows. You can also finish clips with AI video upscaling when you need sharper delivery assets.
