Music streamer Spotify’s new AI-powered DJ not only curates playlists it thinks you’ll love based on your listening habits, it adds spoken commentary between tracks, just like an actual radio disc jockey. The voice is modeled on that of Xavier “X” Jernigan, Spotify’s head of cultural partnerships. “It sounded so realistic when we were building it that nobody realized it wasn’t a real voice but, in fact, AI,” says Spotify’s co-president and chief product officer, Gustav Söderström. Spotify DJ is now available to Spotify Premium subscribers in 50 countries.
