PostEaseThe short answer
YouTube auto dubbing, or automatic dubbing, generates translated audio tracks for your videos, so a viewer who speaks another language can listen in theirs. Dubs are made when you upload, published with your video, and marked “auto-dubbed” in the description; viewers can switch between the original and dubbed tracks.
YouTube’s Help Center says it is “enabled by default for eligible creators,” and that “over time, we may also generate dubs for previously published videos.” You cannot edit a dub, but you can review dubs before they publish, or turn the feature off.
Why a video may not be dubbed
YouTube lists the reasons a video is not eligible:
| Reason | What YouTube says |
|---|---|
| Length | The video exceeds 120 minutes |
| Speech | No speech, only music, or very little spoken content |
| Language | The original audio is in a language not yet supported, or could not be detected |
| Pacing | Speech so fast the dub would be unlistenably sped up |
| Copyright | The video contains copyrighted content |
Which languages
Coverage depends on the original language. An English video can be dubbed into 20 languages: Arabic, Bengali, Dutch, French, German, Hebrew, Hindi, Indonesian, Italian, Japanese, Korean, Malayalam, Polish, Portuguese, Punjabi, Russian, Spanish, Tamil, Telugu and Ukrainian. Most other original languages are dubbed into English, and a few into more, such as Spanish into Arabic, English and Portuguese.
Some languages support expressive speech, which YouTube says “replicates the original audio’s pitch and intonation,” though it will not always be used. An experimental lip sync option, open to select channels, alters the speaker’s lip movement to match the dub; YouTube announced it at Made on YouTube in September 2025, when it said dubbing covered “20 different languages,” and the event’s main announcement listed “upgrades to auto-dubbing” among its Studio tools.
Auto dubbing or your own dubs
YouTube offers a second route, multi-language audio, where you upload dubs you recorded or commissioned:
| What differs | Automatic dubbing | Multi-language audio |
|---|---|---|
| Who makes the track | YouTube, generated on upload | You, recorded before uploading |
| Editing | Dubs cannot be edited; fix the source language to regenerate | Replace the file with a new one |
| Eligibility | On by default for eligible creators | Creators with advanced features |
| Also offers | Expressive speech in some languages; experimental lip sync | Localised thumbnails for long-form videos |
| A language with both | An existing auto dub must be deleted first | Then your own track can be uploaded |
Getting better dubs
Most dub errors trace back to the source. From YouTube’s guidance:
- Set the original video or channel language correctly before uploading; a wrong language means mistranslated dubs.
- If dubs come out mistranslated, correct the original language and YouTube regenerates them.
- Turn on Manually review dubs before publishing, in Settings, Channel, Advanced settings, to preview each dub first.
- Expect trouble with proper nouns, idioms, jargon, strong accents and background noise; speak clearly over a quiet track.
- Translate your title and description too: YouTube says viewers searching in their language can find translated titles and descriptions.
Auto dubbing and PostEase
PostEase uploads YouTube videos on schedule with their title, description and cover. It does not set a video language on upload, so YouTube relies on your channel language or detects it: set your channel language in YouTube Studio before your first scheduled upload, and turn on manual review there if you want to check dubs before they publish. YouTube, X, LinkedIn (personal profile), Pinterest, Bluesky, and WordPress publishing are live today; Instagram, TikTok, Facebook, and Threads are pending each platform's own API approval.
Questions
Is YouTube auto dubbing on by default?
Yes, for eligible creators. It can be turned off, or set to manual review, in YouTube Studio under Settings, Channel, Advanced settings.
Can I edit an auto dub?
No. You can correct the video’s original language to regenerate dubs, delete a dub, or upload your own track for that language instead.
How long can a video be for auto dubbing?
Up to 120 minutes. Longer videos are not eligible.
Do dubbed videos show up in search in other languages?
YouTube says videos can be found by translated titles and descriptions, so translate those alongside the audio.
