Abstract:	It is known that certain aeracoustic phenomena inside the the vocal tract are responsible for the deviations from the linear model of  speech. Recent theories claim that turbulence inside the vocal system are responsible for Amplitude and Frequency Modulations (AM-FM) of  the acoustic signal. In this talk we will present a novel algorithm for AM-FM demodulation and its applications to speech signals.
Biography:	Nikolaos Vasiloglou graduated from National Technical University of Athens Greece. He joined CSIP in Fall 2001 as a PhD student working on the general problem of Auditory Scene Analysis. His research is funded by HP Labs.
