About us

Our research is focused on signal and information processing for sound such as speech or music. Recent research issues include blind source separation, sound-to-light conversion device "Blinky", source enhancement and source localization based on microphone array, acoustic scene classification, sound modification for music, speech analysis for autism spectrum disorder (ASD), and so on. We are working on not only theory and algorithm, also realization as real system through fabrication of microphone array or implementation on smart phone.
Demo movies are here.
