Add a Dubbed Audio Track to a YouTube Video
YouTube lets one video carry several languages, so viewers hear it in theirs without you posting a second video. This makes the track: dub your video here, tick "Also give me the new sound on its own", and upload the MP3 in YouTube Studio under Languages.
Your video stays on your device. How?
Only the sound is sent to be written out, and only the words to be translated and spoken; none of it is kept. The music is separated and your new video is made on your device.
Select or drop a video or recording
A video (MP4, MOV, WebM) or a recording (MP3, M4A, WAV), with someone speaking. Free up to 5 minutes.

- About 7,000 characters of speech a day per visitor — one 5-minute video, or several short ones.
- The MP3 of the dubbed sound is free too; tick the box under More options before you start.
- Longer videos: the first 5 minutes free, the whole thing with ClipUtils Pro, up to 60 minutes of video a week.
How to add a dubbed audio track to a YouTube video
Dub the video here
Pick your video and the language. Under More options, tick "Also give me the new sound on its own" before you start.
Download the MP3
When it finishes, the MP3 sits beside the video download. That file is the audio track.
Open YouTube Studio
Go to Studio on a computer — multi-language audio can't be managed in the phone app — and open the video.
Add the language
Languages → Add language, choose the language, and upload the MP3 as its audio track. The original track stays as it is.
One video, several languages
Posting a translated version as a separate video splits your audience, your comments and your analytics, and starts the new video from zero. A second audio track on the video you already have keeps all of that in one place, and YouTube serves the right track by the viewer's own language setting.
YouTube's own automatic dubbing covers some of this, but it leaves out videos over two hours, videos with little speech, and videos carrying copyrighted music — and it gives you no choice of voice and no file you can download. Making the track yourself gets around all four.
What's in the track, and why that matters
The MP3 is the complete new sound: the AI voice and the video's own background music, mixed, running the same length as the part you dubbed. It is not a bare voice recording, which matters because a track with the voice alone would play against silence where your music used to be.
That is a real failure mode with dubbing tools that strip the music: the second language gets a lifeless version of the video. Here the music is separated from the original speaker on your device and kept under the new voice, so the Hindi or Spanish track sounds like the same video.
YouTube will not overwrite a track that is already there, so adding a language is safe: your original stays the default and the new one appears beside it.
Features
An MP3, not just a video
Tick one box and the dubbed sound comes down on its own, which is what YouTube's Languages screen asks for.
Music included
The track carries the video's own music under the new voice, so the second language doesn't play against silence.
Same length as the original
Each line is timed to where it was spoken, so the track lines up with the picture already on YouTube.
Free, and no account
Up to 5 minutes of video, with no sign-up — the track included.
Frequently asked questions
How do I add another language's audio to a YouTube video?
Dub the video here with "Also give me the new sound on its own" ticked, download the MP3, then in YouTube Studio on a computer open the video and go to Languages → Add language, and upload the MP3 as that language's audio track.
Will it replace my original audio?
No. YouTube keeps the original as the default track and adds the new language beside it. Viewers get the one that matches their language setting.
Can I do this from the YouTube app on my phone?
The dubbing works on a phone, but YouTube's multi-language audio is managed in Studio on a computer. Make the MP3 on your phone and upload it from a computer.
Does the track include the background music?
Yes. The original speaker is separated from the music on your device and the new voice is mixed over that music, so the track sounds like the same video rather than a voice over silence.
Is my video uploaded?
No. Only the sound is sent to be written out, and only the text to be translated and spoken; neither is kept. The picture never leaves your device, and the finished video is put together there.
