Spotify is bringing more AI-narrated audiobooks to its platform via a new partnership with ElevenLabs. On Thursday, the audio streaming giant announced it would begin accepting audiobooks recorded using ElevenLabs’ AI voice software, saying it “recognizes the potential of digital voice-narration to grow and expand the audiobook market.”

The expansion means that audiobooks on Spotify can now be narrated in 29 languages thanks to ElevenLabs' excellent natural-sounding speech technology. The AI software will give authors tools to control the voice and intonation of the narrator to create the best-sounding non-human audio possible.
