Research

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.
