Variety: “YouTube expands Multi-Language Audio Tracks”

The multi-language audio feature lets creators add dubbing to new and existing videos, helping them expand their global reach and reach new audiences for their channels, according to YouTube. In early tests with a “handful” of creators, including MrBeast, YouTube has seen more than 3,500 multi-language videos uploaded in 40-plus languages as of January 2023. Creators testing multi-language dubbed videos saw more than 15% of their watch time coming from views in the video’s non-primary language in January, according to YouTube.


To use YouTube’s multi-language dubbing feature, when uploading a video to their channel, eligible creators can add different audio tracks through the Subtitles Editor tool. Existing content in creators’ catalogs can be updated with additional audio tracks as well. If you’re a viewer, just click the video’s settings to see what audio tracks are available to start watching in another language. In addition, content with multiple language tracks will default to match viewers’ preferred language and users will be able to search for multilingual content via translated video titles and descriptions.

This actually sounds like a perfect use case for AI voice synthesis and various adjacent tools: record the primary audio track normally in the creator’s main language, automatically transcribe and translate it to a selection of additional languages (the creator may optionally double-check the quality of the transcription and tweak the translation, provided he knows the target language), and finally generate new audio tracks in these languages in the creator’s own voice.

Otherwise, I don’t see this system scaling well at all. At this point, MrBeast is practically an entire business onto itself – beside a handful of massively popular creators, who would have the means and connections to hire a Naruto voice actor to dub their videos in Japanese!? Without automated tools, this feature will be another case of helping the already successful ‘win more’ at the expense of medium-sized and small channels who cannot afford the time, effort or expenditure to record multiple tracks for their videos in languages they most likely don’t master.
