Professor Campos-Astorkiza works on phonetics and phonology from a myriad of perspectives including laboratory phonology, sociophonetics, and second language acquisition. In Lab Phonology, her research combines theory with experimental methodologies and illustrates how phonetic data, both from production and perception, can help us develop models to explain sound patterns. In terms of sociophonetics, she is interested in phonetic variation in two areas: dialectal phonetic variation and the role of bi/multilingualism, and speech adaptation in popular music. Finally, her work on second language acquisition of phonology focuses on new methodologies and instructional implications. She leads Our Voices/Nuestras Voces, a project that combines pedagogy and research in linguistics focusing on the acquisition of Spanish pronunciation by L1 speakers of English.
