I am a researcher in the field of spoken language technology. I received the B.S. in Engineering, M.S. in Informatics, and Ph.D. in Informatics from Kyoto University, Kyoto, Japan, in 2004, 2006, and 2014, respectively.
My research interests include automatic speech recognition (ASR) and a wide range of spoken language technologies such as speaker diarization, spoken dialog systems and spoken document retrieval systems. My recent research focuses on the development of algorithms for far-field multi-talker conversational ASR, whose outcome includes the 1st prize at the IWSLT English speech recognition evaluation campaign in 2014, the 2nd prize at the CHiME-5 speech recognition competition in 2018, and the 1st prize at the speaker diarization track of the VoxCeleb Speaker Recognition Challenge in 2020.
Prior to joining Microsoft in 2019, I was a Senior Researcher at Hitachi Ltd., Tokyo, Japan, where I served from 2006 to 2019. I also conducted research at the National Institute of Information and Communications Technology (NICT), Kyoto, Japan, as a Research Expert (2014-2016) and Cooperative Visiting Researcher (2016-2017). I am a member of the Institute of Electrical and Electronics Engineers (IEEE), the Acoustical Society of Japan (ASJ), the Japanese Society for Artificial Intelligence (JSAI), and the Information Processing Society of Japan (IPSJ).
