Lexical Tone vs. F0 Effects on VOT in Cantonese.
(Unpublished)
Abstract
This study investigates the effects of lexical tone on the Voice Onset Time (VOT) of prevocalic stops in Cantonese. It builds on literature showing how various factors affect VOT without a resultant loss in phonological contrast and also ties in a body of research on tone and consonant interaction. The specific research questions addressed are (1) Does tone have an effect on VOT in Cantonese?; (2) If so, what kind of an effect does it have?; and (3) Is this effect purely an automatic articulatory consequence of F0 modulation or is this effect also mediated by lexical tone and hence a secondary cue that contributes towards maintaining phonological contrasts between different tonal categories? To address these questions, the speech of 6 native speakers (5 male and 1 female) of Hong Kong Cantonese was examined. A total of 80 tokens of words contrasting in tone and aspiration were analyzed for each speaker for a grand total of 480 tokens. Results from an ANOVA test showed that there is a statistically significant effect (p
