Research 
Research activity in the Centre for Speech and Language Therapy is primarily concerned with phonological acquisition in typical and atypical populations, with a particular focus on the phonological development of bilingual children and adults. Much of this research is conducted collaboratively with the ESRC Centre for Research on Bilingualism in Theory and Practice, Bangor University.

Recent projects include work on sociophonetic variation in Welsh-English bilinguals, first language attrition in the speech of bilingual monozygotic twins (both with Ineke Mennen, ESRC Centre for Research on Bilingualism in Theory and Practice, Bangor University), consonant cluster acquisition in Welsh-English bilingual children, individual variation in the development of L2 vowel perception (with Paola Escudero, Institute of Phonetic Sciences, University of Amsterdam), an acoustic study of the vowels of Northern and Southern Welsh, and a project on the nature of front rounded vowels (with Torsten Müller, Ruhr Universität Bochum, Germany).

The Centre currently has two PhD students: Rhonwen Jones, who is working on early phonological development in Welsh-English bilingual children, and Sarah Patten, who is investigating the efficacy of speech perception assessments in hearing-impaired children.
