My research investigates factors that affect how listeners identify and make use of linguistically relevant acoustic properties (cues) in the speech signal. One aspect of this research focuses on the role of linguistic experience, examining the effects of both long-term experience during the acquisition of a native language and short-term experience from laboratory training or preceding context. The other component of my research investigates how the processing of acoustic cues is affected by age-related changes in hearing, alone and in combination with age-related changes to cognitive mechanisms such as working memory and selective attention. I have also studied the production, perception and learning of Cantonese lexical tones, and factors contributing to the intelligibility of synthetic speech. I regularly teach courses in aging and communication, acoustics, and phonetics, and occasionally in research methods and attention.
