Profile

Tetsuji Ogawa received his B.S., M.S., and Ph.D. in electrical engineering from Waseda University in Tokyo, Japan, in 2000, 2002, and 2005. He was a Research Associate from 2004 to 2007 and a Visiting Lecturer in 2007 at Waseda University. He was an Assistant Professor atWaseda Institute for Advanced Study from 2007 to 2012. He has been an Associate Professor at Waseda University and Egypt-Japan University of Science and Technology (E-JUST) since 2012. He was a Visiting Scholar in the Center for Language and Speech Processing, Johns Hopkins University, Baltimore, MD, from June to September in 2012 and from June to August in 2013, and a Visiting Scholar in Speech Processing Group, Faculty of Information Technology, Brno University of Technology, Czech Republic from June to July in 2014 and May to August in 2015. His research interests include stochastic modeling for pattern recognition, speech enhancement, and speech and speaker recognition. He is a member of the Institute for of Electrical and Electronics Engineering (IEEE), Information Processing Society of Japan (IPSJ) and Acoustic Society of Japan (ASJ). He received the Awaya Prize Young Researcher Award from the ASJ in 2011 and Yamashita SIG Research Award from the IPSJ in 2013.

A study on total optimization of multiple pattern recognition systems using cooperative and adaptive training
Project Year: Apr 2013 - Mar 2016
Attempts have been made to cooperatively optimize multiple pattern recognition systems, developing a total system efficiently and automatically. Specifically, the clustering technique that is robust against the environmental changes and multistrea...
Effective improvement of time-series pattern recognition systems using clustering and unsupervised adaptive training
Project Year: Apr 2011 - Mar 2013
I developed technologies for clustering speech data into acoustic attributes such as speakers and types of noise and technologies for adaptively optimizing speech recognition systems in unsupervised ways. The developed technologies would be essent...
Project Year: 2008 - 2010
We sophisticated generation/recognition methods of linguistic and paralinguistic information and achieved a communication robot which can make conversation with a group of people. The robot was used to stimulate activity of the human to human conv...
