Center for Speech, Language, and Hearing Research
Candace Hicks, Ph.D., CCC-A
Director, Center for Speech, Language, and Hearing Research
The Center for Speech, Language, and Hearing Research (CSLHR) is embedded within the
School of Health Professions, and is administered through the Department of Speech,
Language, and Hearing Sciences at Texas Tech University Health Sciences Center (TTUHSC).
The primary mission of the CSLHR is to promote education, research, and clinical practice
in the areas of speech, language, and hearing. The Center's goal is to facilitate
a collaborative effort among faculty in the programs of audiology, speech-language
pathology, and rehabilitation sciences within the School of Health Professions and
faculty from other programs within TTUHSC and Texas Tech University (TTU) who have
interest and expertise in normal processes, disorders, or treatment of speech, language,
swallowing, hearing, or balance systems.
The CSLHR laboratories are located on the 3rd floor of the Texas Tech University Health Sciences Center building in Lubbock, Texas
(3B-302). Each research laboratory is run by a full-time, doctoral level faculty member in
the Department of Speech, Language, and Hearing Sciences. The research laboratories are listed below.

(ADHD), Down syndrome, learning disability, specific language impairment, developmental
language disorder, dyslexia, and dysgraphia
- voice problems, including hoarseness or breathiness
- swallowing problems
