My research is primarily concerned with the basic mechanisms of speech production and perception in connected discourse, especially in terms of how multiple layers of communicative meanings can be encoded through a common process of articulation. In particular, I am interested in the production, perception, typology, and modelling and synthesis of speech prosody, as well as the basic mechanisms of coarticulation. I am also concerned with computational modeling of the neural process of speech acquisition. More recently, I have developed an interest in the understanding of emotional expressions in speech from an evolutionary perspective. For more information, please see my Research page.
