How to Auto-Dub a YouTube Video

The two ways to auto-dub a YouTube video

If you're watching: a browser extension generates the dub on your side, in real time, for YouTube videos you open on a computer. You choose the target language and voice. There is a short initial load; you do not wait for the entire video to process. See the YouTube dubbing extension page for where this helps most.

If you're publishing: YouTube's built-in auto-dubbing generates translated audio tracks for your uploads automatically — on eligible channels, in the languages it supports. New to the feature? Start with what auto-dubbing on YouTube actually is.

How to dub a YouTube video while you watch

Install AutoDub in Chrome, Edge, Brave or Firefox on your computer. Open any YouTube video, click AutoDub, pick a language and press play. AutoDub offers 42 target languages. Turn on bilingual subtitles when you want the original line next to the translation.

1. Install AutoDub. It's free on the Chrome Web Store and works in Chrome, Edge, Brave, and other Chromium browsers. There is also a Firefox Add-ons version, and an installation guide if your browser can't reach the store.
2. Open any YouTube video. Stay on the YouTube watch page. If the video was already open when you installed AutoDub, reload the page so the player can show the AutoDub button.
3. Click AutoDub. Move the pointer over the player and click AutoDub on the right side of the control bar. The panel opens and translation starts.
4. Pick your language — and a voice. Set Dubbing language to the language you want to hear. AutoDub detects the original language on its own. If the default voice isn't to your taste, open Dubbing and switch it.
5. Press play and listen. The dub is generated in real time and stays in sync with the video. Under Translated subtitles, choose Translation + original to read both languages. Balance the dub against the original audio so the speaker never fully disappears.

How to auto-dub your own YouTube videos

Open YouTube Studio on a computer. Availability depends on your channel and video; check your settings rather than assuming a Partner Program membership guarantees a dub.

1. Check the setting. In YouTube Studio, go to Settings → Channel → Advanced settings and check "Allow automatic dubbing". If it is not enabled, look for an early-access Enable option. Save your changes.
2. Set each video's language correctly. Confirm the original language in the video details. Incorrect language metadata can lead to mistranslation. YouTube cannot edit an automatic dub; correcting the source language makes it generate the tracks again.
3. Upload as usual. Dubs generate automatically for the languages YouTube supports. In Advanced settings, check "Manually review dubs before publishing" and save if you want to listen first. This controls publication, not a guaranteed completion time.
4. Review the results. Open Content → select your video → Languages. Select an available language and preview its audio. Publish an acceptable track, or leave it unpublished. Unpublish a live track to withdraw it; delete only if you do not intend to republish it. YouTube says preview, publish and delete are available in Studio on a computer.

Not every video qualifies. YouTube lists these limits: uploads over 120 minutes, videos with little or no speech, unsupported languages, source language it cannot detect, speech too fast to dub, and videos with copyright claims. The full list of limits — and what the "auto-dubbed" label means for your viewers — is in our auto-dubbing explainer.

The Studio mobile app can turn the channel setting on or off under Settings → Content → Automatic dubbing, and can require manual publish. Managing a specific video's tracks still happens on a computer.

YouTube’s official automatic-dubbing instructions cover current availability, languages and publication controls.

Watch vs publish: what actually changes

A published YouTube audio track is available to viewers where YouTube supports it. An AutoDub session plays only in the viewer's browser; it does not add an audio track to your channel.

If you cannot get a dub

Watching: missing button or no sound

After installing, reload the video page and move the pointer over the player controls. Check that the extension is enabled and allowed to run on youtube.com. If the button is there but there is no sound, check Dubbing is on, the dubbing volume, and whether the tab or device is muted. Allow the first section to load.

See the step-by-step troubleshooting guide for missing buttons, loading and automatic-start problems.

Publishing: a language or track is missing

Check the video’s Languages page, its original language and the eligibility limits above. A channel setting does not guarantee a track for every upload or language. YouTube does not let you directly edit automatic dubs. Correct an incorrectly set source language, or review your other audio options in Studio.
