Abstract

Results & Discussion. Initial data analysis for four speakers indicates that onset lags in coda (including concatenated nasals at a morpheme juncture) and singleton onset nasals are similar—the velum lowers before TT constriction formation begins (Fig 2a), with onset nasals showing greater timing variability overall (Fig 2c). On the other hand, singleton onset nasals have shorter or lags (near-zero lag) than coda and geminate nasals (Fig 2b, d). There is also large individual variation in the or lag for onset nasals. In addition, while onset nasals have shorter and smaller velum lowering than coda nasals, no such distinction is found between coda nasals and geminate nasals. Findings on velum actions in nasals suggest that the nasality is weakened in the onset position, and the process of nasal weakening may create comcomitant greater variability. This study of intergestural timing under prosodic variations reveals articulatory grounding for phonological phenomena commonly observed in Korean such as denasalization or nasal weakening. In sum, intergestural timing is not merely a function of contextual overlap and variation, but rather intrinsic to the representational specification for these segment-sized gestural molecules combined with their syllabic structural properties.
