Speech Perception

A central focus of my dissertation research is an investigation of how both auditory and visual speech perception can constrain articulatory patterns, and how phonological systems are shaped by (and optimized for) both auditory and visual perceptibility.

Building on work in articulatory variability in the Northern Cities Vowel Shift, Youngah Do and I have found that variants of fronted /ɔ/ that retain their lip rounding are less likely to be misperceived as /ɑ/ than variants that are produced with unround lips. This finding suggests both that when undergoing fronting, vowels may preferably retain their rounding in order to maximize perceptibility in both the auditory and visual domains. This work was presented at a meeting of the Acoustical Society of America in December 2016.
