Prof. Barnes teaches classes in phonetics and phonology, and is also the director of the Phonology Lab. His research interests lie primarily at the interface between phonetics and phonology, especially in the areas of prosody and intonation. Most of his focus is on the dynamic, many-to-many mappings between properties of the acoustic signal and abstract linguistic categories in speech production and speech perception. Specific topics include the perceptual integration of acoustic cues to prosodic categories such as intonational pitch events, and the role of perceptual patterns in structuring the cross-language typology of prosodic grammars.
