YouTube has teamed up with music artists including John Legend and Sia to offer AI-generated versions of their singing voices as soundtracks for creator videos. The Google-owned video platform is using a music generation model created by the search company's AI unit to produce the unique 30-second clips in a limited trial. The nine artists are: Alec Benjamin, Charlie Puth, Charli XCX, Demi Lovato, John Legend, Sia, T-Pain, Troye Sivan and Papoose. YouTube said the experiment, called Dream Track, has been opened to a small group of US creators using its Shorts feature – the platform's answer to TikTok. In a blogpost, YouTube said creators would be able to produce a 30-second soundtrack by typing a text prompt.
