Dr. Peter RichtsmeierDr. Richtsmeier conducts research on phonological learning in children and adults. With children, his current studies examine 1) factors that contribute to the development and persistence of phonological errors, especially in children with speech sound disorder, and 2) factors that allow children to be more accurate speakers. With adults, current studies examine 1) factors that allow adults to learn phonological patterns, and 2) the basic cognitive skills required for phonological learning.

Dr. Valerie FreemanDr. Freeman studies how acoustic-phonetic aspects of speech production and sociolinguistic perception vary with social factors like regional dialect, stance-taking, and hearing status. Her current work investigates the lived experiences and social quality of life of d/Deaf and hard-of-heraing people, including how they are perceived socially when others hear their speech. Her other projects examine remote data collection methods, regional vowel mergers, and ways to train abled native speakers to better understand accented and pathologized speech. |

Dr. Roha KaipaDr. Kaipa examines the effect of bilingualism/multilingualism on language learning, language processing and language production. Her outcome measures include electrophysiological (electromyography & electroencephalography) and behavioral measures. |
