Shannon Barrios is an Associate Professor in the Department of Linguistics at the University of Utah, where she has served since 2022. She co-directs the Speech Acquisition Lab and specializes in second language acquisition, phonetics/phonology, and psycholinguistics. Her research explores how adult learners develop perceptual and lexical representations of novel phonological contrasts, with a focus on cross-language speech perception, orthographic effects, and social factors in input processing. BA, Spanish (SUNY Geneseo, 2004) MA, Linguistics (Syracuse University, 2007) PhD, Linguistics (University of Maryland, 2013) Her research interests span adult second language acquisition , phonolexical development , and accent bias . She investigates how learners process phonological contrasts, the role of orthography in speech perception, and the influence of social roles (e.g., teachers vs. peers) on language learning. Her work combines behavioral experiments, ERP/MEG neuroimaging, and computational modeling. Barrios’ recent publications (2024–2020) focus on representational fuzziness , talker variability , and lexical contrast mechanisms . Her 2024 Languages paper proposes a factorial typology for evaluating auditory word recognition scenarios, while her 2024 JASA Express study highlights individual listener variation in cross-language speech perception. Earlier works examine allophone acquisition, orthographic input effects, and neural correlates of phonological mapping. She has received two teaching awards from the University of Maryland (2013). Her teaching portfolio includes undergraduate and graduate courses in phonetics , psycholinguistics , and second language acquisition theory . She also leads workshops on research ethics, mentee development, and academic literacies.
