YouTube Auto Dubbing Explained: On, Off and Limits

YouTube auto dubbing is a YouTube feature that turns the speech in an uploaded video into translated audio tracks in other languages, made by AI with nothing for the creator to record. Viewers can set a preferred audio language or switch back to the original, and the video's description marks it as "auto-dubbed".

That is the short answer. The rest of this guide covers who gets the feature, which languages it works in, why some videos are never dubbed, how to turn it off or on as a creator and as a viewer, what it cannot do, and when it makes sense to dub a video yourself. If you came here because the two names look alike: AutoDub is a separate web app, not this YouTube feature, and AutoDub vs YouTube auto dubbing puts the two side by side.

Every YouTube fact below comes from three YouTube Help pages, all checked on November 4, 2026: Use automatic dubbing, Watch videos in your preferred language and Add Multi-language features to your videos. YouTube changes this feature often, so check those pages before you rely on a detail.

What YouTube auto dubbing does

When you upload a new video, YouTube generates the dubs on its own and publishes them according to your channel's publication settings. YouTube Help adds that "over time, we may also generate dubs for previously published videos", which is why creators sometimes find dubs on older uploads they never touched.

A dub is an extra audio track on the same video, not a new upload. YouTube Help says viewers "can indicate their preferred languages for audio, titles and descriptions", or switch between the original and the dubbed tracks on any video.

YouTube also says dubs "may be regenerated to improve the quality, and the quality may not be the same across all languages." Some target languages support what YouTube calls expressive speech, "which replicates the original audio's pitch and intonation to produce more natural-sounding dubs", but YouTube adds that even where a language supports it, "it won't always be used."

Who gets it

YouTube Help says the feature "is enabled by default for eligible creators". The page does not list what makes a channel eligible. If your channel does not have it, the same page says you can turn on early access by clicking Enable in "Advanced settings" in YouTube Studio. To see which languages one particular video can get, open that video's Languages page in YouTube Studio.

Which languages YouTube dubs

The Help page lists 30 original languages. An English video can be dubbed into 20 languages; most other languages can only be dubbed into English. YouTube notes it is "gradually expanding support for new languages", so some channels get new ones sooner.

So a French video can get an English dub, but not a Spanish or a German one, and a Japanese video gets English only.

Why a video is not auto dubbed

YouTube Help gives six reasons a video may be ineligible:

1. Length: the video is longer than 120 minutes.
2. No speech: it has no speech, only music, or very little spoken content.
3. Unsupported language: the original audio is in a language YouTube does not support yet.
4. Detection failed: YouTube could not detect the source language of the audio.
5. Fast speech: the speech is so fast that the dub would sound sped-up.
6. Copyright: the video contains copyrighted content.

One more thing to check: the original language. YouTube says that if a video's default language is set incorrectly, its dubs "may be mistranslated". Set the right original language and the dubs are generated again.

How to turn YouTube auto dubbing off or on (creators)

YouTube Help says you can turn auto dubbing on or off at any time.

On a computer

1. Sign in to YouTube Studio.
2. Click Settings, then Channel, then Advanced settings.
3. Uncheck Allow automatic dubbing to turn it off, or check it to turn it on.
4. To approve each dub yourself, also check Manually review dubs before publishing.
5. Click Save.

In the YouTube Studio app

1. Open the YouTube Studio app and tap your profile picture.
2. Tap Settings.
3. Under Content, tap Automatic dubbing.
4. Turn it on or off; tap Publish manually to review dubs before they go live.

For one video

Previewing, publishing, unpublishing and deleting a dub only works in YouTube Studio on a computer: open Content, pick the video, click Languages, hover over the language and use the menu in the Audio column. An unpublished dub can be republished later; a deleted dub cannot.

How to hear the original audio (viewers)

To switch one video back to the original sound:

1. Open the video.
2. In the player, select Settings (the gear).
3. Select Audio track.
4. Choose the language you want.

To stop dubs on every video in a language you already understand, add that language to your preferred languages. On a computer: click your profile picture, click Settings, click Playback & Performance, then under Language click "add or edit languages", select your languages and click confirm. YouTube says that content with the original audio in one of your preferred languages "will not be translated and will default to the original audio", and that this applies to dubs, titles and descriptions.

Source: YouTube Help, "Watch videos in your preferred language", checked November 4, 2026. That page describes no other viewer switch for dubs.

What YouTube auto dubbing cannot do

• You cannot fix the words. YouTube Help says it plainly: "You cannot edit automatic dubs." You can review the transcript and publish, unpublish or delete a dub, and you can correct the original language so the dubs are made again, but you cannot change a mistranslated line.
• It does not promise your voice. Expressive speech copies pitch and intonation in some languages, and YouTube lists "difficulty matching the voice used for dubbing to the original voice" among the known issues. The page does not say the dub uses a copy of your own voice.
• Lip-sync is not standard. YouTube describes lip sync, which "alters the speaker's lip movement to align with the dubbed audio", as an experimental feature with early access for select channels, qualifying videos and languages only.
• Errors happen. YouTube warns about mispronunciations, accents, dialects, background noise, and trouble with proper nouns, idioms and jargon.
• It stays on YouTube. The dub is an audio track on your YouTube video, with YouTube's language directions. It does nothing for the same clip on TikTok, Instagram or your course platform.

One common belief is wrong, though: you can review dubs before viewers hear them. Check Manually review dubs before publishing, and nothing goes live until you publish it.

When to dub the video yourself

Auto dubbing works well enough for many channels. Making your own dub makes sense when you need what it leaves out: your own voice in every language, lip movements that match the new language without waiting for early access, a target language your source language cannot get on YouTube, or the same dub on other platforms.

With AutoDub you upload the file or paste the YouTube link (an MP4, MOV, M4V or WebM file, up to 30 minutes and 2 GB) and pick the language. AI video dubbing gives you back an MP4 in the speaker's cloned voice with lip-sync, plus subtitles as SRT and VTT files. Each dub is one language; on a paid plan you can pick up to five languages in one submission, each made as its own dub. Popular directions have their own guides, such as English to Spanish video translation and English to Hindi video translation; the video translation hub lists every pair. AutoDub has no script editor either, so watch the dub before you publish it. If you are new to the technology, start with what AI dubbing is and how it works, and read whether AI dubbing is safe for your voice and your data and the legal side of dubbing a video before you upload.

You then have two ways to put the dub on YouTube:

1. Upload it as its own video, for example on a channel in that language. Viewers see the lip-synced picture.
2. Add it to the original video as an audio track. YouTube Help says multi-language audio "is currently available to creators with access to Advanced features", and that files "must be in a supported audio-only file format and roughly the same length as your video". So you export the audio from the dubbed MP4 first, and viewers see your original picture, without the lip-sync. If YouTube already made an automatic dub in that language, you must delete it before you upload your own. Our guide to YouTube multi-language audio tracks walks through it.

You can try this on one video first. The AutoDub free trial dubs your first video, up to 2 minutes, into one language, and you watch the whole dub in your browser. Downloading the MP4 and its subtitles comes with a plan or a one-video unlock; the pricing page has the numbers, and our breakdown of AI dubbing cost per minute puts them next to the rest of the market.

AutoDub specs and limits

What AutoDub accepts, what it returns, and what it does not do yet.

What AutoDub does not do yet

• No script editor. You cannot edit the transcript or the translation of a dub, so watch every dub before you publish it.
• No public API. Every dub is started in the web app; there is no API for teams yet.
• One language per dub. Each dub has one target language and is billed as its own dub. Paid plans can pick several languages in one submission; the free trial is one video in one language.
• 30 minutes and 2 GB per video. A longer or larger video has to be split into parts before you upload it.
• Subtitles only in the new language. The SRT and VTT files are in the dubbed language; there is no subtitle file in the original language.
• Links from three sites. AutoDub fetches YouTube, TikTok and Instagram links; a video from anywhere else has to be uploaded as a file.
• No accent or dialect setting. You pick a language, such as Spanish, not a regional variety of it.
• No automatic deletion. Nothing is removed for you: your videos and dubs stay in your account until you delete them in your dashboard.
• Downloads need a plan or an unlock. A free trial dub can be watched, not downloaded: the video and its subtitles download with a plan or a one-time unlock from $4.99.

YouTube auto dubbing: frequently asked questions

Why is YouTube auto dubbing not working on my video?

YouTube Help lists six reasons a video is skipped: it is longer than 120 minutes; it has no speech, only music or very little talking; its language is not supported; YouTube could not detect the language; the speech is too fast; or it contains copyrighted content. Also check that the feature is on (Settings, Channel, Advanced settings, "Allow automatic dubbing") and that the video's original language is set correctly. If your channel does not have the feature, YouTube says you can turn on early access with the Enable button in Advanced settings.

How do I turn off auto dubbing on YouTube?

As a creator: in YouTube Studio on a computer, go to Settings, Channel, Advanced settings, uncheck "Allow automatic dubbing" and click Save; in the Studio app, go to Settings, then Automatic dubbing under Content. As a viewer: pick the original in the player's Settings, Audio track menu, or add the languages you understand to your preferred languages, so videos in those languages keep their original audio.

Is YouTube auto dubbing good?

It is useful for reach, and it costs you no recording time. YouTube itself says quality may not be the same across languages, that dubs can contain errors from accents, background noise, names, idioms and jargon, and that you cannot edit them. Turn on manual review and preview each dub before it goes live; publish only the ones you would be happy for a native speaker to hear.

Does YouTube auto dubbing keep my own voice?

Not as a promise. In languages that support expressive speech, YouTube copies the pitch and intonation of the original, but it lists matching the dub's voice to the original voice as a known issue, and its Help page does not say it uses a copy of your voice. If you want to sound like yourself in every language, a dub made with a cloned voice, such as one from AutoDub, is the way to get it.

Is YouTube auto dubbing only for partnered channels?

YouTube Help does not say that. On November 4, 2026 it said only that the feature is "enabled by default for eligible creators", without listing the criteria, and that a channel without it can turn on early access with the Enable button in Advanced settings. Uploading your own audio tracks is a separate feature, which YouTube limits to creators with access to Advanced features.

Can I edit an auto-dubbed track on YouTube?

No. YouTube Help says "You cannot edit automatic dubs." You can preview a dub, read its transcript, and publish, unpublish or delete it in YouTube Studio on a computer. If the dub is wrong because the original language was set incorrectly, fix the language and YouTube generates the dubs again. To replace a dub with your own, delete it and upload your own audio track.
