- Fellowship in 2018 at University College London
Dr. William Choi is an Assistant Professor of Speech-Language Pathology at The University of Hong Kong. He graduated from The University of Hong Kong with a BSc (First Class Honours, 2014) and PhD (2018) in Speech and Hearing Sciences. On a Fulbright Scholarship, he joined the Massachusetts Institute of Technology (MIT) as a Fulbright Scholar in 2017-2018. Subsequently, Dr. Choi moved to the University College London as a Croucher Postdoctoral Fellow, with the support of the Croucher Postdoctoral Fellowship.
Dr. Choi's research focuses on suprasegmental speech perception. He actively investigates how language experience shapes the perception of Cantonese tones, English stress, and non-linguistic pitch. In a study published in Cognition, Dr. Choi and his team discovered that Cantonese-English bilinguals perceived English stress more accurately than did native English listeners. This ground-breaking finding bucked the usual assumption that non-native listeners are always disadvantaged compared with native listeners. In a follow-up study, Dr. Choi further examined this Cantonese advantage and identified its behavioral and neurophysiological constraints. Based on collective research, Dr. Choi proposed the Acoustic-Attentional-Contextual hypothesis which has led to a major theoretical advancement in understanding positive transfer in cross-linguistic speech perception.
In addition to bilingualism, Dr. Choi is also interested in exploring the connectivity of music and language. He keenly investigates how musical experience facilitates speech perception, and how language experience enhances music perception. In 2020, Dr. Choi investigated the effect of musical experience on Cantonese tone perception by native English listeners. The study showed that musical experience only facilitated the perception of some—but not all—Cantonese tones. This surprising finding (referred by Dr. Choi as “the selectivity of musical advantage”) informs the need to refine contemporary theories of cross-domain plasticity.
Besides research, Dr. Choi engages in academic and community services. He is an Associate Editor of Frontiers in Psychology, Frontiers in Communication, and Deafness & Education International. He has also served as an external reviewer for the HKSAR government and private funders.
