YouTube auto dubbing adds AI-translated audio tracks to videos, and for many viewers the translated track is what starts playing. There is no single switch that stops all dubs, but each side has a setting that does most of the work:
- Viewers: add the languages you understand to your preferred languages (Settings > Playback & Performance > Language). A video whose original audio is in one of those languages plays the original. For a single video, open the player's Settings > Audio track and pick the original.
- Creators: in YouTube Studio, go to Settings > Channel > Advanced settings and uncheck Allow automatic dubbing.
The rest of this guide covers what each setting changes, how to review or delete dubs that already exist, and why some videos never get dubbed.
What YouTube auto dubbing does
Auto dubbing takes a video's spoken audio, translates it, and publishes the result as an extra audio track. On February 4, 2026, YouTube made it available to everyone, with 27 languages. Eight of them (English, French, German, Hindi, Indonesian, Italian, Portuguese and Spanish) support expressive speech, which tries to keep the speaker's pitch and intonation. YouTube says that in December 2025 more than 6 million viewers a day watched at least 10 minutes of dubbed content.
Two details explain most of the confusion:
- Dubbed videos are labeled auto-dubbed in the description. The label is the quickest way to tell a dub from a creator's own voice.
- Unless you set preferred languages, YouTube chooses the audio language from your watch history. That is why a video in a language you speak can still start in translation.
YouTube is also testing lip sync, which adjusts the speaker's mouth movements to match the dub. It is experimental and limited to select channels.

How to turn off auto dubbing as a viewer
| What you want | What to do |
|---|---|
| Always hear the original in languages you understand | Profile picture > Settings > Playback & Performance > under Language, add or edit languages, select them, confirm |
| Switch one video back to the original | Player Settings (gear icon) > Audio track > choose the original language |
The preferred language list is the closest thing to an off switch. YouTube's help page says content with original audio in one of your preferred languages "will not be translated and will default to the original audio." The same rule covers translated titles and descriptions. If you're bilingual, add both languages.
Videos in a language you didn't add can still play dubbed. For those, switch the audio track on that video.
The setting is separate from your app language and location. YouTube says it doesn't change search results or recommendations. You can set it on the web or in the YouTube app.

How to turn off auto dubbing for your channel
Auto dubbing is on by default for eligible creators. To turn it off:
- Sign in to YouTube Studio.
- Go to Settings > Channel > Advanced settings.
- Uncheck Allow automatic dubbing.
- Click Save.
You can turn it back on from the same screen. If you'd rather approve each dub than turn the feature off, keep Allow automatic dubbing checked and also check Manually review dubs before publishing. Dubs then wait for you instead of going live on their own.
YouTube's help page doesn't say whether turning the setting off removes dubs that are already live. YouTube also says it may generate dubs for videos you published before. To be sure a dub is gone, check the video's Languages page, covered next.
Review, unpublish or delete a dub
Managing dubs works only in YouTube Studio on a computer. Open Content, select the video, then click Languages.
| Task | Where |
|---|---|
| Preview a dub | Click the language in the Language column, then pick it in the Preview menu under the video |
| Read the dub transcript | Click the language, then in the Audio row open the options menu and choose Review |
| Publish, unpublish or delete | Hover over the language, open the menu in the Audio column, choose an action |
An unpublished dub can be published again later. A deleted dub can't be brought back.
You can't edit the words in a dub. If a dub was translated from the wrong language, change the video's original language to the correct one, and YouTube generates the dubs again.
Why a video doesn't get dubbed
YouTube skips videos when:
- the video is longer than 120 minutes
- there is no speech, only music, or very little talking
- the original language isn't supported, or YouTube couldn't detect it
- the speech is too fast to dub without speeding it up
- the video contains copyrighted content
Language support isn't symmetric. English videos can be dubbed into 20 languages. Most other supported languages are dubbed only into English, with a few extra pairs, such as Spanish into Portuguese and Arabic. For a specific video, the Languages page in Studio lists what's available.

How creators get better dubs
YouTube's help page and its Creator Liaison suggest a few habits:
- Set the original language correctly when you upload. If it's wrong, the dubs may be mistranslated. You can't edit a dub, but you can fix the language.
- Speak clearly and avoid overlapping speech. YouTube lists both as format changes that improve dubs.
- Add translated titles and descriptions. Viewers see the title before they hear the dub.
- Check results by language. YouTube Studio's analytics have an audio track filter that shows how each language performs.
YouTube also says having videos dubbed has no negative effect on how they are discovered.

Auto dubbing and scheduled uploads
YouTube's video upload API has no dubbing setting. A scheduling tool can't turn dubbing on or off for one video, so the channel setting in Studio is what decides, for scheduled uploads as much as for uploads made in Studio.
The API does have a field for the language spoken in the video's audio, defaultAudioLanguage. Solnk's public API and MCP server accept it as default_audio_language in the YouTube settings. If you schedule videos that way, or have an AI agent schedule them, set it so each upload states its language instead of relying on your channel default or YouTube's detection.
