RANDY DIEHL
Professor and David Bruton Jr. Regents Chair in Liberal Arts
As a lab, we are devoted to understanding how people perceive speech. Our current focus is at the level of the phoneme. We use various methods to achieve this goal; including acoustic analysis of natural speech, perceptual identification and discrimination of synthetic speech sounds, perceptual identification and discrimination of non-speech sounds, and the representation of speech sounds in computer models of the auditory nerve.
