Google Translate live transcription improvements

Naveen Arivazhagan and Colin Cherry wrote a post for the Google AI Blog about how they solved a problem with the live speech translation feature in Google Translate: translations would frequently get updated as more of the transcribed text became available, which users found distracting. It’s a cool glimpse into all the stuff besides just model accuracy and speed that are important to get right for a successful AI-powered product, and into how engineers think about turning these nonfunctional requirements into measurable performance metics they can optimize for.
