Dr. Carrell specializes in the field of speech perception. He teaches courses in phonetics, speech science, multicultural aspects of speech pathology, and speech perception and processing. His research currently focuses on three areas: 1. Speech perception in noise via auditory-object formation; 2. Speech perception in cochlear implant listeners; and 3. Speech perception by children with learning problems. Dr. Carrell studies these phenomena using techniques and models from audiology, speech science, psychology, and engineering. He views the speech waveform as a communication channel between two individual brains just as the corpus callosum is a communication channel between the two halves of a single brain. Like neuronal signals, speech is highly encoded, redundant, fault-tolerant, and is not yet completely deciphered. Dr. Carrell states that the central role of speech in cognition combined with its accessibility makes speech perception an irresistible object of study.
