Summary: Phonetic category formation refers to the processes by which bilingual or second language (L2) speakers come to distinguish phonetic details of shared phonemes in each language (Flege, 1995). For example, Spanish and English share the phoneme /p/, but /p/ in each language is produced with different voice-onset-time (VOT) values. Thus, it is an interesting question whether bilingual or L2 speakers exhibit accurate phonetic realizations of Spanish /p/ and English /p/ when speaking the two languages. While phonetic category formation has been investigated extensively in adult bilingual and L2 speakers, little research has been carried out with bilingual children. The main goal of this presentation is to address how phonetic categories are formed and developed in Korean-English bilingual children and to evaluate developmental patterns of speech production in the bilingual children. Stop and vowel production of four different age groups (3, 5, 7, and 10 years of age) of Korean-English bilingual children in the US were examined. The findings provide novel information that reports the developmental processes of phonetic category formation and its underlying mechanisms in bilingual children. This study was funded by the National Institute of Child Health and Human Development (RHD061527A).

 

Speaker Biography: Dr. Sue Ann Lee is an associate professor in the Department of Speech, Language & Hearing Sciences at Texas Tech University Health Sciences Center. Dr. Lee earned her bachelor’s degree from Ewha Womans University in South Korea, her Master’s degree from The Ohio State University and her Ph.D. in Speech Pathology at the University of Texas at Austin. Dr. Lee’s research interest lies in three areas. First, her early work focused on characterizing child’s speech behaviors as well as mothers’ speech input. Second, her research also focuses on characterizing phonetic category formation in Korean-English bilingual children. With an R03 funding from NICHD, she investigated how phonetic categories of English and Korean consonants and vowels develop in Korean-English bilingual children and what type of underlying mechanism occurs in this process. Finally, her recent research focuses on examining speech therapy efficacy using various technology such as ultrasound and telepractice. Dr. Lee has received external grants from the National Institutes of Health, CH Foundation and the South Plains Foundation. Her work has been presented at number of international conferences and published in multiple high impact journals such as the Journal of Child Language and Journal of Speech-Language and b Hearing Research.
