How Duolingo is using AI to humanize virtual language lessons

July 05, 2019 / PAUL SAWERS

“The core part of our AI strategy is to get as close as possible to having a human-to-human experience,” Duolingo AI and research head Burr Settles told VentureBeat in an interview at London’s AI Summit last month. Duolingo, for the uninitiated, is a cross-platform app where users can learn languages for free, though they can also cough up $7 each month for a premium service that removes ads, delivers offline access, and more. Through gamification and bite-sized lessons, anyone can learn to read, listen, and speak in dozens of tongues.
