AI Lip Sync — Make Every Word Look Naturally Spoken

New Audio, Natural Delivery

Replace the original delivery with a new voice track while keeping the face, framing, and visual identity intact. Mouth shapes follow individual sounds, and expression moves with the performance, so the result feels spoken rather than overlaid.

One Portrait, Any Voice

Start with a single clear portrait and add speech in the voice and language you need. Saymo turns the still image into a synchronized talking performance while preserving the subject's recognizable appearance.

Any Language, Matched Mouth Shapes

Create localized versions in more than 100 languages. The model adapts mouth movement to each language's phonetics and pacing, helping translated voiceovers look native without frame-by-frame corrections.

How To Use

How to Make an AI Lip Sync Video

Go from source media and audio to a synchronized video in four simple steps, with no keyframing or manual mouth animation.

step 01

Choose a Mode

Use Image to Video to animate a portrait, or Video to Video to replace the speech in footage you already have.

step 02

Upload Your Source

Add a clear portrait photo or video with the speaker's face visible. You can also select a preset from the Avatar Library.

step 03

Add the New Audio

Upload dialogue, a translated voiceover, or a song. For two-person scenes, arrange each speaker's audio on the timeline.

step 04

Generate & Download

Generate the synchronized result, review the mouth timing, and download a clean video ready to publish or deliver.
