Tóm tắt

Abstract Recent work has demonstrated that progressively stronger prosodic boundaries result in increasing amounts of lengthening for consonant gestures, both preceding and following the boundary. The present experiment extends these earlier findings by considering kinematic data collected with a magnetometer to determine (1) if vocalic gestures demonstrate lengthening patterns comparable to those of consonantal gestures due to adjacent prosodic boundaries, and (2) if the relative timing of consonant and vowel gestures is affected by adjacent boundaries. A magnetometer system was used to track articulator movements of 3 speakers producing sentences in which a /...C<sub>1</sub>V<sub>1</sub>(#)C<sub>2</sub>V<sub>2</sub>.../ sequence was embedded with varying medial boundaries. All subjects demonstrated lengthening of the vocalic articulation before stronger boundaries. Additionally, effects on the relative timing of words spanning a boundary and the relative timing of segments in boundary-adjacent syllables were observed.
