The Speech Research Laboratory
The Speech Research Laboratory investigates speech perception
and aims to improve speech recognition for adults with hearing
loss. One line of research is focused on improving sentence-level
speechreading abilities via computer-based training programs
(funded by Butler University Holcomb Faculty Research Grant
#027096). A secondary line of research is focused on the relative
contribution of vowels and consonants to auditory-visual speech
perception, for adults with normal hearing and adults with hearing
loss (funded by an American Speech-Language-Hearing Foundation
Research Grant for New Investigators).
All persons affiliated with this lab work to create an
atmosphere of respect for persons, and work to protect the rights
and welfare of people who work as research participants in the
Speech Research Laboratory.
Research participants are always needed!
We are always looking for adult listeners (18-70 years of age)
with normal hearing or with hearing loss, to take part in our paid
studies. Participants must have normal or corrected-to-normal
vision, and be speakers of American English. The Speech Research
Laboratory is located in Jordan Hall, room 248A. Free visitor
parking is also available on campus, for study participants. In
order to learn more about our ongoing work, please email Dr. Carrie Richie or call (317)
