- Abstract
- An articulatory study was conducted to explore effects of prosodic boundary and syllable structure on temporal realizations of /ma/ in C#V vs. #CV in Korean (where '#' denotes an Intonational Phrase or a Word boundary). The vocalic gesture underwent boundary-induced lengthening more in C#V than in #CV, implying that the boundary effect is largely localized to the initial element whether consonantal or vocalic. CV coordination patterns were temporally neutralized between #CV and C#V in the phrase-internal Word boundary condition, showing a possible 'resyllabifiation' of 'C' with the following vowel in C#V in the articulatory temporal measures taken in the present study. It was suggested that CV gestures in C#V, whose phasing relationship has to be determined postlexically, reorganize temporally in an in-phase coupling mode just like the way CV gestures are phased in #CV. Finally, while there was leftward shifting of the consonantal gesture in C#V with some temporal variability across an IP vs. a Word boundary, intergestural timing in #CV remained invariant regardless of boundary strength. But the most stable temporal pattern was observed with an IP boundary in #CV, interpretable as an important temporal characteristic of domain-initial strengthening. Some of these results were further discussed in terms of their implications for the theory of it-gesture and the gestural coupling model of syllable structure. (C) 2014 Elsevier Ltd.
