- Speech perception
- Psychophysics
Dr. Mark Hedrick has been with UT since 1997. His research is principally centered
on perception of speech by individuals with hearing loss. He is involved in determining
what information from the speech signal the listener with hearing loss pays most attention
to, and how this may be different from listeners with normal hearing. He is also involved
in examining how degraded listening conditions (noise, reverberation) specifically
alter listeners’ perception of speech at the phoneme level. He investigates the effects
of aging and spectral shaping of consonants upon listeners’ perception and neural
representation, and has studied the effects of nicotine upon perception, along with
examining the effects of auditory training programs.
