AI lip sync

Make a photo speak any voice track

Lip Sync takes a photo of a person and an audio file, and generates a video of that face speaking in time with the recording. It starts from a still photo, not from a video you already have. Upload both, choose from the settings currently shown in the tool, and review the exact credit cost before creating.

How it works

From input to video in three steps

  1. 01

    Add the photo

    Choose a photo of the person who should speak. A clear, front-facing face gives the model the most to work with.

  2. 02

    Attach the audio

    Add the voice track the mouth movement should follow. The tool accepts an audio file alongside the photo.

  3. 03

    Check the cost and create

    Pick from the settings currently shown, confirm the credit cost on the action button and submit.

Practical guidance

What makes a photo easy to sync

Lip sync works from the face in your photo and the voice in your recording. The clearer both are, the less the model has to guess.

Use a clear, front-facing face

Pick a sharp, well-lit photo where the mouth is visible and not covered by hands, hair or heavy shadow.

Use clean audio

A recording with a clear voice and little background noise is easier to match than a crowded mix.

Trim the recording first

Cut silence and anything you do not want spoken before you upload, so the result covers only the part you need. The tool shows which audio files it accepts.

Questions

Frequently asked questions

What do I need to create a lip sync video?

A photo showing the person who should speak, and an audio file with the voice track. Both are added in the Lip Sync tool before you create.

Can I add a voice to a video I already have?

Not with Lip Sync. It starts from a still photo and turns it into a talking video. To give a new video sound, switch the Audio option on when you create it, on the tools that offer it.

Does it work with any language?

The tool follows the audio you provide rather than a script, so the spoken language is whatever is in your recording.

Can I use a voice I generated elsewhere?

You attach an audio file, so any recording you own and are permitted to use can be the source track.

Start with the idea you have now

Write the scene or add your source image. You will see the available controls and exact credit cost before creating.
