About myself
I am Senior Research Scientist at the Signal Processing Research Group, Media Information Laboratory, NTT Communication Science Laboratories, Kyoto, Japan.
I received an M.Eng. from the Free University of Brussels, Brussels, Belgium, and the Ecole Centrale Paris, Paris, France, in 2003 and a Ph.D. from the Graduate School of Information Science and Technology, Hokkaido University, in 2007. I joined NTT Communication Science Laboratories as a research associate in 2007 and became a permanent research scientist in 2012. I am also a visiting lecturer at the Faculty of Science and Engineering, Waseda University, Tokyo since 2015, where I teach information theory.
My research interests include robust multi-microphone speech recognition, acoustic model adaptation, integration of speech enhancement front-end and recognition back-end, speech enhancement, and speech dereverberation. I was involved in the development of NTT robust speech recognition systems for the REVERB, CHiME 1 and 3 challenges, which all achieved best performance results in the tasks.
I also took an active part in the organization of the REVERB challenge and workshop 2014 and of ASRU 2017 (Automatic Speech Recognition and Understanding Workshop) and was a senior affiliate at the 2015 Jelinek summer workshop. I gave tutorials about distant speech recognition at Interspeech 2016 and APSIPA 2016 and was an invited speaker of GlobalSIP 2015. I received several awards, including the 2006 Student Paper Award from the Institute of Electrical and Electronics Engineers (IEEE) Kansai branch, the 2006 Sato Paper Award from ASJ, the 2015 IEEE ASRU Best Paper Award Honorable Mention, and the 2016 ASJ Awaya Young Researcher Award. I am a senior member of IEEE and a member of ASJ.
I am married and have two kids.
