Apple is rolling out audiobooks narrated by artificial intelligence, reports the Guardian's Leyland Cecco. The company recently unveiled a series of fiction and romance audiobooks featuring "digital narration" on its Apple Books platform, which allows readers to browse and buy e-books and audiobooks. The two current A.I. narrators are called Madison, a soprano, and Jackson, a baritone, per Apple's website. In the future, the company plans to also offer A.I.-narrated nonfiction and self-development audiobooks and will be rolling out two additional digital voices named Helena and Mitchell. According to the Guardian, Apple approached independent publishers in recent months and asked them to participate in its digital narration initiative.
