Perceptual constancy in audition

My PhD research was funded within an EPSRC project on perceptual constancy in audition.

Reverberation poses a problem for artificial listening devices, and automatic speech recognition suffers increased error rates when reflected sound energy is present. My approach to this topic lies in the development of computational models based on psychoacoustic principles of hearing. Like people, these models use auditory feedback signals to glean environmental clues from contextual sound, and use these clues to inform their recognition of spoken words in reverberant rooms. Unlike existing methods of dereverberation, the proposed strategy addresses the rapid changes in acoustic conditions that occur in every-day listening.
