In a move aimed at breaking language barriers, YouTube has rolled out a major upgrade to its auto-dubbing feature, making it easier for viewers to discover and watch content from creators across the world.
The update is part of YouTube’s broader effort to make “global stories feel local” while giving both users and creators greater control over how content is experienced. With this expansion, auto-dubbing now supports 27 languages, marking a sharp increase from earlier capabilities.
The platform has also opened auto-dubbing access to all users. This feature automatically translates and voices videos into multiple languages. User engagement around the tool has grown quickly. In December, more than 6,000,000 viewers watched at least 10 minutes of auto-dubbed content every day, highlighting rising demand for multilingual videos.
Alongside wider access, YouTube has focused on improving audio quality. It has introduced a new feature called Expressive Speech across all channels in 8 key languages: English, French, German, Hindi, Indonesian, Italian, Portuguese, and Spanish. This upgrade is designed to better capture a creator’s original tone and emotion, reducing the flat or robotic sound often associated with dubbed audio.
Viewers are also getting more control over their viewing preferences. YouTube has launched a new Preferred Language setting, allowing users to choose whether they want to watch videos in the original language or in a dubbed version. This works alongside the platform’s existing system, which uses watch history to decide the default language version.
To further improve realism, YouTube is testing a lip-sync pilot that subtly aligns a speaker’s lip movements with translated audio. Although still in the testing phase, the feature signals the platform’s next steps in making dubbed videos feel more natural and visually consistent.
For creators, YouTube has added automatic smart filtering. This feature identifies content that should not be dubbed, such as music-only uploads or silent vlogs, helping maintain authenticity. The platform has also clarified that auto-dubbed videos will not impact content discovery or rankings and may help creators reach wider audiences in other languages.
