The function will allow you to attract a wider audience and will probably save the company a lot of space on the servers, because you no longer need to upload a lot of videos in different languages, but it is enough to make one with several audio tracks. are much smaller in size.

what is known

Everything will work similarly with subtitles: the viewer opens the settings menu in the player of a particular video and selects the desired language from the list.

It is worth noting that third-party dubbing is not automatically generated (for example artificial intelligence based on automatic translation of subtitles). Additional audio tracks will be uploaded by the channel authors themselves. Therefore, for this they will either have to create their own sound (and therefore know the language) or collaborate with dubbing studios for this. Therefore, it can be assumed that the new opportunity will only be used in certain situations: movie studios, news agencies, international organizations that want to get their material worldwide. But For example, casual YouTubers making vlogs or other entertainment videos are unlikely to need this functionality..

• In initial testing, the feature was used on more than 3,500 videos uploaded in 40 languages.
• As of January, more than 15 percent of dubbed videos were viewed in languages ​​other than the original language of the video.
• YouTube also reported that in January alone, viewers watched more than 2 million hours of dubbed videos on the platform every day.

Initially, dubbing will only be supported for long YouTube content, but the company says it’s already testing the feature for short videos as well.

The ability to customize the video soundtrack is currently available worldwide: YouTube on desktop, mobile, tablet and TV.
