I am a phonetician and laboratory phonologist. Much of my research focuses on the production, acoustics, and perception of coarticulation. One long-standing goal of this work is to better understand human speech perception, including how coarticulatory variation facilitates the listener’s task. Another goal is to understand how coarticulatory variation might lead to innovation and new phonetic norms in a speech community. My recent work has especially studied the relation between innovative (or conservative) perception and production at the level of the individual speaker-listener, with a special interest in the potential implications of the perception-production relation for sound change.
