We’ve seen generative AI and large language models do some amazing things in the past year — but how do you go from a tech demo to a real shipping product? In this Release Notes episode of the NerdOut@Spotify podcast, we’ll hear about what it took to ship our Voice Translation pilot, which takes podcasts recorded in English and uses AI to generate the original podcaster’s voice speaking in Spanish (with German and French coming next).
Host Dave Zolotusky talks with senior machine learning engineering manager Sandeep Ghael about how we brought expertise from across the company in order to go from a weekend prototype to releasing fully translated episodes of Lex Fridman, Armchair Expert, and other podcasts — in just six weeks.
