Research Areas: Speech Communication

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.
