Main research

Articulatory and Acoustic Phonetics

Our research focus is on speech production and second-language acquisition of pronunciation. Experimental phonetics - both articulatory and acoustic phonetics - underlies most of our work and we specialize in using ultrasound as a tool to view and measure the tongue during speech. More specific research interests currently include Articulatory Settings (as seen through inter-speech rest posture) in monolinguals and bilinguals, as well as phonetic and phonological issues involved in learning to pronounce a second language. We are also interested in the Aizu dialect of Japanese, and we have recorded and analyzed many audio samples of this dialect.
