How to Auto-Dub a YouTube Video

People mean two different things by this. Either you're watching a video in a language you don't speak — or you made a video and want the world to hear it in theirs. Both take about two minutes to set up. Here's how to do each.

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 any video that has captions. You choose the language and the voice. No waiting on the creator, no waiting on YouTube.

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 any YouTube video while you watch

This route works on the video in front of you — whether or not the channel has dubs, in any of 22 languages.

  1. Install AutoDub. It's free on the Chrome Web Store and works in Chrome, Edge, Brave, and other Chromium browsers. There's a Firefox version on Firefox Add-ons, and a manual install guide if your browser can't reach the store.
  2. Open the video you want to watch. An AutoDub button appears in the player control bar, next to the settings gear. Sign in with email or Google the first time — that keeps bots from burning through the service.
  3. Pick your language — and a voice. AutoDub detects the original language on its own; you just choose what you want to hear. If the default voice isn't to your taste, switch it.
  4. Press play. The dub is generated in real time and stays in sync with the video. Bilingual subtitles show the original text next to the translation, and you can balance the dub against the original audio so the speaker never fully disappears.

The one requirement: the video needs a caption track (YouTube's auto-generated captions count). Live streams aren't supported yet. The user guide covers the finer points.

How to auto-dub your own YouTube videos

If your channel is in the YouTube Partner Program, this is mostly already happening — the setting ships turned on. To make sure, and to get better results:

  1. Check the setting. In YouTube Studio, go to Settings → Channel → Advanced settings and confirm "Allow automatic dubbing" is checked.
  2. Set each video's language correctly. This is the single biggest quality lever — a wrong source language garbles every translation downstream.
  3. Upload as usual. Dubs generate automatically for the languages YouTube supports. Turn on "publish manually" if you want to hear them before your audience does.
  4. Review the results. Each video's Languages tab in Studio lists the generated tracks — listen, and unpublish or delete any that miss the mark.

Not every video qualifies: YouTube skips uploads over 120 minutes, videos with little or very fast speech, unsupported languages, and anything with a Content ID claim. The full list of limits — and what the "auto-dubbed" label means for your viewers — is in our auto-dubbing explainer.

Which route do you need?

If you're trying to understand a video, the extension is the whole answer — you don't need the creator to do anything. If you're a creator, do both: let YouTube dub your uploads in the languages it covers, and know that viewers can use AutoDub for every language and every video it doesn't.

Frequently asked questions

How do I auto-dub a YouTube video that doesn't have a dub?

Use a browser extension. YouTube only dubs videos from eligible channels, and viewers can't request one. AutoDub generates the dub on your side instead — install it, open the video, pick a language, and press play. It works on any video that has captions.

Is auto-dubbing YouTube videos free?

Both routes are free. YouTube's built-in auto-dubbing costs creators nothing, and the AutoDub extension is free for viewers with no daily limit — you just need to sign in with email or Google.

How do I use the YouTube dubbing extension?

Install AutoDub from the Chrome Web Store, open any YouTube video, and click the AutoDub button in the player control bar. Choose your language and press play — the dub is generated in real time while you watch, with bilingual subtitles.

Can I download a YouTube video with the auto-dub?

No. AutoDub plays the dub in real time in your browser and doesn't download or modify the video. YouTube's own dubbed tracks also stay on YouTube — there's no export.

Why doesn't my video have an auto-dub option?

YouTube skips videos longer than 120 minutes, videos with little or very fast speech, unsupported languages, and videos with Content ID claims. If your channel isn't eligible yet, viewers can still hear your video in their language with the AutoDub extension.

Does auto-dubbing work on mobile?

YouTube's own dubs play on mobile automatically when a video has them. Browser extensions like AutoDub are desktop-only — Chrome, Edge, Brave, and Firefox.
