Re-voice and audio in a video
What you can do about the voice and sound of a video today: lip sync at creation, and the Audio tools to change a voice, dub or clean a recording.
#What it is
There is no Re-voice button on a finished video card. This page says what you can do today to change the voice or sound of a video, and which Audio tools work on a recording you bring.
#Who can use it
Pro only. Video is part of the Pro plan, and accounts on a trial get the Pro audio features. The backend checks your plan for the voice changer, dubbing and noise removal, and for making videos. On Free, these modes show a Pro badge.
#Cost
Uses credits. The voice changer, dubbing and noise removal are charged by the length of your file, and a hold is taken first. Lip sync is part of the video price. See Price before you confirm.
#Where to find it
For lip sync, use the video composer. For the other tools, open the Audio tab on Home or Audio mode in a Studio project, press the mode chip and look under Edit audio.
#Buttons and controls
| # | Name in the app | What it does | Plan |
|---|---|---|---|
| 1 | Lip sync | A switch in the video composer. Turns on your avatar's voice with matching lips. See Voice. | Pro |
| 2 | Voice changer | In Edit audio. Re-voices a recording in another voice. Its subtitle reads "Re-voice a recording". The button reads Change voice. | Pro |
| 3 | Dub a video | In Edit audio. Makes your video or audio in another language. Its subtitle reads "Your video in another language". The button reads Dub it. | Pro |
| 4 | Remove noise | In Edit audio. Keeps the voice and drops the background. The button reads Clean it. | Pro |
| Dub into (language) | A language picker that shows with Dub a video. It has a search box, "Search language...". | Pro | |
| Re-voice | A button on a finished audio take. It does not show on video cards. | Pro |
#How to turn on your voice for a new video
- Pick your avatar in the plus menu.
- Pick a model that shows the Lip sync switch.
- Turn Lip sync on, then press Create video.
To change the voice of a video you already made, make a new one with the setting you want. See Edit a finished video for what a chat change can and cannot do.
#How to dub a video into another language
- Open Audio mode and press the mode chip.
- Under Edit audio, choose Dub a video.
- Upload your video or audio file.
- Choose the language in Dub into.
- Press Dub it. The result appears as a new card.
#How to change the voice in a recording
- Open Audio mode and choose Voice changer under Edit audio.
- Upload an audio recording.
- Pick the voice you want.
- Press Change voice. The result appears as a new take.
#How to remove background noise
- Open Audio mode and choose Remove noise under Edit audio.
- Upload an audio recording.
- Press Clean it.
#How to add your own narration or music
- Press the plus button in the composer and choose Add photos & files.
- Pick an audio file.
- In Role for (file name), choose narration for a spoken recording, or music_bed for background music.
- Tick the rights and consent box and press Create video.
Your recording is mixed with the footage. A narration recording does not match the lips of a person on screen, so use Lip sync for that.
#Options explained
What works on a video. Only Dub a video takes a video file. Voice changer and Remove noise take audio files. To use them on the sound of a video, you need the audio as its own file.
What the dub makes. If you upload a video, the result is a dubbed video. If you upload audio, the result is dubbed audio.
Re-voice on an audio take. A finished audio take has a Re-voice panel with Voice, Style, Speed and Pitch. It makes a new take from the same words and keeps the original. It does not show for video.
Lip sync on or off. On: your avatar speaks in your voice and the lips match, and the model's own music is replaced by our music track. Off: the model keeps its own voice, music and sound.
Captions and subtitles. For text of what is said, see Captions and transcription.
#Limits
- A file for the voice changer, dubbing or noise removal can be up to 50 MB.
- Dubbing is limited to 10 minutes per file.
- Noise removal needs at least 5 seconds of audio.

#Questions
#Can I change the voice of a video I already made?
Not with a button or a chat message today. Make a new video with the avatar and the Lip sync setting you want. For audio-only changes, use the tools above on a recording.
#Can I add my own music or narration to a video?
Yes, when you create it. Attach an audio file with the plus button and set its role to narration or music_bed. See the section on your own audio above. You cannot add it to a video that is already finished.
#Can I dub my finished video?
Yes. Save the video, then upload it to Dub a video in Audio mode. It makes a new file in the language you pick.
#Does the voice changer work on a video file?
It takes audio files. Use Dub a video for a video, or take the audio out first.
#Is there an audio mixer for video?
The Mix with music panel is on audio cards, not on video cards.
