YouTube launches video dubbing feature in different languages. YouTube’s multilingual voiceover technology will be built in, but creators will have to work with third-party voiceover providers. However, there is no information about particular ones that will be available.
Once the video is uploaded, viewers can select their preferred audio track from the same menu where they can currently adjust other options such as subtitles or audio quality. The content creator must indicate which other language they want to support.
YouTube has tested the feature with a small group of video contributors and the feature has been used in more than 3,500 videos in 40 languages. As of last month, more than 15% of viewers watched videos in their native language. In January alone, the volume of these views exceeded 2 million hours.
The well-known blogger Mr. Beast has previously worked to promote his material translated into other languages. He did this by making separate channels for dubbed videos. Some of these channels are incredibly popular, giving an opportunity to expand your audience and find new ways to make money. By displaying videos to a multilingual audience, the new feature is expected to make it simpler for a variety of creators to increase monetization income. This will be profitable for both the platform and the creators.

The function is currently only enabled for long videos, but it is being tested in shorts.
Content creators will be informed when the new function in Creator Studio is available. The function will initially be made available to only several thousand as a part of testing. When more authors will be able to use this choice on a regular basis is currently unknown.
It will be fascinating to observe how this feature spreads throughout YouTube and especially how it will be integrated into YouTube Shorts. However, it is not yet reported how dubbing will be used in the short videos. Presumably, with the development of YouTube’s embedded dubbing, we should expect AI-generated subtitles to be added later.
