How to replace YouTube's auto-dub with your own audio track

If your upload keeps failing, this is almost certainly why: YouTube will not accept your own dubbed track for a language that already has an automatic dub sitting in it. Their own help page says it plainly. If an automatic dub already exists for a language, you have to delete it before uploading your own version.

Delete first, upload second. Get that order wrong and nothing you do in Studio will work, and the interface will not tell you what's wrong.

Here's the whole procedure, plus how to produce a file YouTube will accept.

How do I delete an auto dub?

In YouTube Studio on a computer:

1. Open Languages in the left menu.
2. Click the video you want to change.
3. Under Audio, click Delete next to the language you're replacing.

One warning before you click it. YouTube says that once a dub is deleted it won't be available and you can't republish it. So if the auto dub is currently live and getting views, have your replacement file ready before you delete anything. There's no undo and no way back to the automatic version for that language.

If you'd rather stop auto dubs appearing at all, that's a separate switch: Content, then Automatic Dubbing, in Studio settings. Automatic dubbing is on by default for eligible creators, which is why so many people find dubs they never asked for.

How do I upload my own dub?

Same screen, once the language is clear:

1. Languages in the left menu, then click the video.
2. Click Add Language and pick your language.
3. Next to Dub, click Add.
4. Click Select file and choose your audio file.
5. Click Publish.

YouTube's requirement for that file is short: it must be in a supported audio-only file format and roughly the same length as your video.

Audio-only is the part that trips people up. Not a video file with the new language on it. Just the audio.

What file should I actually upload?

Give the dubbing tool your audio, not your video, and you'll get audio back. Our pipeline accepts MP3, WAV, AAC, M4A, FLAC, AIFF, OGA, OGG and Opus, alongside the video formats, so you can hand it an MP3 extracted from your video and skip the conversion step at the other end.

Length is the other half of YouTube's requirement, and it's where AI dubbing behaves differently from a human voice actor. A translated sentence is rarely the same length as the original. German runs long, Japanese runs short, and a dub that drifts will end up out of sync with your video by the end even if it started aligned. Check the finished track against the original before you upload it rather than after.

Our billing is worth understanding here, because it settles on the dubbing service's own measurement rather than ours. We read a duration off your file to quote you a price, then ElevenLabs returns the duration it actually measured, and the difference is charged or refunded so you pay against their number. Credits are minutes, always rounded up, minimum one credit per file. A 3 minute 10 second clip costs 4.

Limits before you start: 2 GB and 180 minutes per file, checked before a single credit is touched. If the file is too big or too long, you find out immediately and you haven't paid for anything.

How many languages can I do at once?

One at a time, and this is the thing people discover after they've bought credits rather than before.

One upload takes one target language. Six audio tracks means six jobs and six charges. There's no batch mode and no multi-select on the upload form, because each job is a separate submission to the dubbing API with its own duration and its own price.

You never pick the source language, though. There's no "from" field anywhere in the product. The original language is detected from the audio itself, so the same source file goes in unchanged for all six.

Credits don't expire, so buying a block and working through your languages over a few weeks costs the same as doing them in an afternoon.

What if the dub fails halfway?

You get your credits back automatically. A job that fails, or that hits the six hour hard timeout without producing a file, refunds what it charged without you asking. So a trial run on one language costs nothing if it doesn't produce something usable.

The real constraint is on the other end. Your finished dub stays downloadable for 90 days and is then deleted from storage permanently. The file you uploaded goes sooner, deleted as soon as the dub is made and in any case within a day.

Download every track you produce and keep it somewhere of your own. YouTube holds the published version, but if you ever need to re-upload after a channel problem, or you delete a dub and want it back, our copy will not be there to save you at month four.

If you want the whole feature rather than this one procedure, including eligibility, file requirements and how many tracks a video can carry, we've written a complete guide to YouTube multi-language audio.

Which languages are worth doing first?

For most English-language channels the answer is Spanish and Portuguese, in that order, on audience size and on how much of that audience will not watch subtitled content.

We have detailed guides for both: dubbing YouTube videos from English to Spanish and dubbing YouTube videos from English to Portuguese. The YouTube dubbing hub covers the rest of the languages we support, and there's a broader use case index if your content is not primarily YouTube.

FAQ

Can I delete a YouTube auto dub?

Yes. In YouTube Studio, open Languages, click the video, and click Delete under Audio next to that language. YouTube states that a deleted dub can't be republished, so produce your replacement before you delete the original if the auto dub is currently live.

Why is YouTube rejecting my dubbed audio upload?

Two common causes. An automatic dub already exists for that language, which blocks your own upload until you delete it. Or the file isn't audio-only: YouTube requires a supported audio-only format, roughly the same length as the video, not a video file with a new soundtrack.

How many audio tracks can one video have?

YouTube doesn't publish a maximum on its multi-language audio help page. The practical limit is your own production: each language is a separate track you produce, upload and maintain, and on our side each one is a separate job with its own charge.

Does replacing the auto dub reset my video's performance?

Swapping an audio track doesn't republish the video or reset its URL, view count or comments. The video stays where it is. Deleting a dub does remove that language option for viewers who were using it, so they fall back to the original audio until your replacement is published.
