The series of events involved in speech communication is called “Speech Chain,” and it is a basic concept in the speech and hearing sciences. We focus on research related to speech communication. The fields of this research are wide-ranging, and our interests include the following interdisciplinary areas:
- education in acoustics (e.g., physical models of human vocal tract),
- acoustic phonetics,
- speech and hearing sciences,
- speech production,
- speech analysis and speech synthesis,
- speech signal processing (e.g., speech enhancement),
- speech / language recognition and spoken language processing,
- speech perception and psychoacoustics,
- acoustics for speech disorders,
- speech processing for hearing impaired,
- speaker characteristics in speech, and
- real-time signal processing using DSP processors.

(Subject of research)
General Acoustics and Education in Acoustics (including vocal-tract models)
Acoustic Phonetics, Applied Linguistics
Speech Science (including speech production), Hearing Science (including speech perception), Cognitive Science
Speech Intelligibility, Speech Processing, Speech Emhancement
Assistive Technology related to Acoustics, Speech and Acoustics for Everybody
Speech Processing, Applications related to Acoustics
Speaker Characteristics of Speech

(Proposed theme of joint or funded research)
acoustic signal processing
speech signal processing
auditory signal processing

  • Apr, 2006 - Jun, 2008
    英語によるプレゼンテーションを学ぶ講義の中で、自分のプレゼンテーションを客観的に学生に示すため、発表風景をビデオに収め、後で学生にそれを見て自己評価させるようにしている。また、同内容で2回目のプレゼンテーションを行わせ、改善する努力を促す工夫もしている。
  • 2003 - Jun, 2008
    音響教育に関する委員会の委員を務め、教育セッション(例えば2006年12月に行われた日米音響学会ジョイント会議における教育セッション)をオーガナイズするなど。
  • 2003 - Jun, 2008
    音響教育に関する委員会の委員を務め、教育セッション(例えば2004年4月に行われた国際音響学会議における教育セッション)をオーガナイズするなど。特に2005年からは委員長を仰せつかり、精力的に活動している(例えば、2006年10月に国立博物館にて科学教室を開催)。
  • Apr, 2002 - Jun, 2008
    本学に赴任して以来、「Progress Report」と称して研究室の教育研究活動に関する報告書を作成し発行している。これにより、研究室の学生の意識の向上にも役立ち、効果を発揮している。
  • Apr, 2002 - Jun, 2008
    普段から英語に慣れておくことが重要であると考え、研究室の定例ミーティングの中で定期的に英語によるミーティングを行っている。また、2006年度からは研究グループごとに行われる毎回の進捗報告も英語で行うことを義務付けている。
