Vowel-dependent variation in Cantonese /s/ from an individual-difference perspective.

Abstract

Individual variation is ubiquitous in the acoustic realization of human speech; however, little is known about the nature of individual differences in coarticulation. Through an in-depth case study of the temporal dynamics of vocalic influences on the acoustic realization of Cantonese /s/, this study demonstrates that coarticulatory effects may vary by the sex and self-reported autistic-like traits of the individual. These findings have significant implications for research in phonetics, phonology, and sound change.
