RESEARCH

My main research interest is Computational Auditory Scene Analysis (CASA), which aims to build machine systems that mimic the ability of human listeners to segregate complex mixtures of sound. I also have interests in reverberation-robust automatic speech recognition, hearing impairment and music technology.

The following book gives an overview of CASA:

DeLiang Wang and Guy J. Brown (editors), Computational auditory scene analysis: Principles, Algorithms, and Applications. IEEE Press/Wiley-Interscience, 2006

The whole book is available online, if you are a subscriber to IEEE Xplore.
