Spotify Uses AI Voice Cloning to Translate Podcasts Into Other Languages
Did your favorite podcaster learn to speak Spanish overnight? No, you’re actually listening to synthetic speech powered by artificial intelligence.
Spotify is using voice-cloning technology to let you hear podcasts in several languages, including Spanish, French, and German. It not only translates the podcaster but does so in their voice.

The technology has raised flags in the security community for its potential to fuel scams. But voice cloning could usher in a new age of real-time translation, which Spotify is seeking to unlock.
“By matching the creator’s own voice, Voice Translation gives listeners around the world the power to discover and be inspired by new podcasters in a more authentic way than ever before,” says Spotify VP of Personalization Ziad Sultan.
