Research Areas

Phonetics, phonology, Computational modeling of linguistic data and interdisciplinary studies involving human-robot interaction

Our research team mainly focuses on computational modelling of speech perception, production cross-linguistically (Chongming Chinese, Nanjing Chinese, Cantonese, Mandarin, Japanese, Korean and English). Recently, our team also started research projects in clinical linguistics such as production and perception of speech prosody in Cantonese-speaking children with and without autism. Our research team has also designed speech and musical training in improving use of prosody to mark information structure. We have also created robot-assisted training programs for autistic children.
