Title:  "Computational Audition: Correlograms and CASA"

Abstract:

The goal of computational audition is to build numerical models of auditory perception that bridge the gap between the neurophysiology and the psychoacoustics.  In this talk, I'll describe the correlogram, a successful model of pitch perception and auditory perception.  I'll describe our work over the years on understanding the cocktail party effect, and the unfortunate path this bottom-up approach took us.  I'll talk about some of the evidence for a combined bottom-up/top-down approach to perception. And describe a hopeful approach.
