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 that speakers may prefer round over unround variants in order to maximize perceptibility in both the auditory and visual domains. These findings were published in Frontiers in Psychology in May 2018.
