YouTube has been making some big announcements for creators at this year's VidCon. 

Yesterday, Mashable reported on the new long-awaited thumbnail A/B split testing feature called Test & Comparewhich will help YouTubers maximize their video views. And now YouTube is working on a potential new way to help creators reach a larger audience: AI-powered multi-language voiceover dubbing for their video content.

The tool is powered by Aloud, an AI dubbing company that is part of Google's own Area 120 startup incubator.

Aloud first provides the creator with a transcription of their video. The user can then edit the transcribed text as they see fit. After the creator signs off on the transcription, Aloud createsan AI voiceover dub for the video. Aloud currently provides this service for free on its website, which is separate from the tool YouTube is building into its platform, but there's currently a waitlist.

A YouTube spokesperson toldThe Verge that the company has already been testing out the AI dubbing tool with "hundreds" of creators.

There are a few pretty big limitations with Aloud, according to the FAQ section on its website. The startup's AI-powered tool currently only works with English-language videos and can only dub into two languages, Spanish and Portuguese, at this time. However, with Google's backing and this new partnership with YouTube, it wouldn't be surprising to see Aloud roll out more language options in the near future.

In February, the company rolled outan option to upload multiple audio tracks for individual videos, sorted by language. Viewers can now simply hit the Settings button on any YouTube video that enables this feature and choose to listen with an alternative audio track in the language of their choice. However, this feature requires creators to supply their own audio, which would require the YouTuber to go out and have their video translated and dubbed on their own.

YouTube's partnership with Aloud to create AI-powered dubs could help YouTubers save both time and money while still broadening their audience.
