Stability of CV Intergestural Timing and Coordination as a Function of Prosodic Boundary and Syllable Structure in Korean

This study examined effects of Prosodic Boundary and Syllable Structure on the CV intergestural timing in Korean, using an EMA. The intergestural timing was more stable in the tautosyllabic (#CV) than in the heterosyllabic (C#V) condition, in line with the lexically-specified intergestural timing hypothesis, and that it was found to be more stable across an IP than a Word boundary. Nevertheless, some aspects of CV coordination remained invariant even when the consonant duration changed. Some evidence was also found, showing both dependency and independency of consonant and vowel gestures. Some of the data were interpretable in terms of gestural coupling relation.
