Tutorial English AI | Online Language Learning AI Assistant Growing with Humans


Project Team

This is an interdisciplinary collaboration between rising researchers in dialogue systems, machine learning, linguistics, learning science, and cognitive science. In this project, Professor Yasuyo Sawaki of the Faculty of Education and Integrated Arts and Sciences, Associate Professor Yusuke Kondo of Waseda University Global Education Center, and Professor Emeritus Michiko Nakano have agreed to study English education and language test design from their expert perspectives, and Waseda University Academic Solutions Corporation (Akira Miura, President and Representative Director; https://www.w-as.jp/) has resolved to jointly provide learning content and experimental environments. The knowledge of Japanese-English speech recognition, previously accumulated via joint research with Dr. Satoshi Kobashikawa, Senior Researcher at Nippon Telegraph and Telephone Corporation (NTT) Media Intelligence Laboratories, will also be utilized. Young researchers at the Perceptual Computing Laboratory, represented by Mao Saeki, Hiroaki Takatsu, and Takao Watanabe are engaged in research and development of multimodal dialogue systems for the project. In addition, an international support team comprising Robotics Institute of Carnegie Mellon University (cognitive modeling), Choitek LLC (VR/AR technology), Intelligent Framework Laboratory Co., Ltd. (crowdsourcing technology), Alt Bridge Technology Co., Ltd. (data security), etc. will also join the project.

Principal Investigator

Dr. Yoichi Matsuyama, the principal investigator, obtained his Ph.D. degree in Computer Science from the Graduate School of Fundamental Science and Engineering at Waseda University in 2014 and was employed as a post-doctoral fellow (special faculty) at Carnegie Mellon University for four and a half years. He has led various research and developmental projects on conversational AI, such as the Socially-Aware Robot Assistant (SARA), which is an official virtual assistant at the World Economic Forum in Davos, an educational tutoring agent (US Science Foundation grant), and joint research projects with Google, Yahoo!, and Microsoft. In 2019, he was appointed Associate Research Professor at Waseda University. In the same year, his group was selected for the “Commercialization of Media Services Utilizing Socially-Smart Conversational AI” grant under the “Program for Creating Start-ups from Advanced Research and Technology” (START) offered by the Japan Science and Technology Agency (JST), amounting to a total of approximately $ 1M.
