I am Yadong Liu, a PhD student in Linguistics at the University of British Columbia. My research focuses on unveiling the unknowns in human speech production using techniques from experimental phonetics and computational modelling. The kind of questions I am interested in includes a. how do the sides of the tongue move during speech production? b. what relationships may hold between speech production and swallowing? c. how does computational modelling help with speech production with speakers who lost a part/parts of their articulators? I work in the Interdisciplinary Speech Research Lab as a researcher.
