Brian Gallagher interviews Paul Raine of ZenGengo and EigoAI. In this episode they discuss his research and experience over the last 2 decades, including text-to-speech, automatic speech recognition, GenAI, and machine translation. As a veteran JALTCALL member since 2011, Paul has contributed in many ways to the EFL community in Japan and beyond. He has developed several web-based language teaching platforms, including Apps4EFL, ABAX LMS, ZenGengo, and now EigoAI, among others. Looking back on the last decade of CALL-related reports and applications, they discuss the technologies that go end-of-life very quickly and those that last the test of time. The problems of link rot and technology aging prompt companies to develop more robust systems and pave the way to better evolution of technology that optimizes the user experience. EigoAI will be the main sponsor at this year’s JALTCALL Conference, where you will be able to meet and talk with Paul in person. We hope you take this great chance. This interview was recorded online in April 2025, prior to the PANSIG conference, with a few extra questions from Geoff Carr.
