After a nearly two-year trial period, YouTube is finally rolling out multilingual dubbing for content creators.

YouTubers will be able to manually upload dubs they've created to existing videos to widen their global reach. And if they don't have the time, resources, or know-how to do it themselves, YouTube will now provide AI features to automatically generate foreign-language dubs in languages like Japanese, Hindi, Spanish, and Korean, courtesy of Google Gemini .

However, perhaps unsurprisingly, YouTube warns that these auto-dubs may make mistakes when it comes to tone or local idioms, so human-made dubs may be best for the creators who can afford them. YouTube says the rollout will happen over the coming weeks and that support for more AI dubs in different languages will be added over time.

Some big-name YouTubers, like MrBeast and British celebrity chef Jamie Olive, have already used the features. YouTube says up to 25% of the test channels' viewers opt for non-English dubs.

YouTube is also testing multilingual thumbnails, which automatically translate video titles into a user's preferred language. For example, a Mexican user whose preferred language is Spanish will automatically get text overlays on top of English-language thumbnails in their native tongue.

The technology behind the rollout is nothing new, and similar features are expected to launch this year on other platforms. Google announced at its I/O event in May that it would begin beta testing automated AI dubs for Google Meet later in 2025, after Microsoft's Teams platform introduced similar tools in November 2024. Meanwhile, Meta-owned Instagram rolled out AI-dubbing tools for its Reels feature in August.
