Lingual kinematics and acoustic durations

Abstract

In a previous paper [J. Acoust. Soc. Am. Suppl. I 71, S105 (1982)] we showed that in /pVCVp/sequences, the duration of the lingual V1C transition was inversely related to the lingual displacement for the CV2 transition, while the displacement and maximum velocity of CV2 were inversely related to the displacement of V1C. Relationships among acoustic durations and these kinematic variables were examined further. The acoustic duration of V1 was related to the duration of the V1C transition, while the duration of V2 was related, less consistently, to both the duration and displacement of the CV2 transition. The duration of V1 (V1 = /a/) was negatively related to the displacement of CV2, but the duration of V2 was not systematically related to the displacement of V1C. In addition, movements toward closure, relative to V1 acoustic onset, started earlier for greater V1C displacements. Movements toward V2, relative to V1 acoustic offset, started earlier for greater CV2 displacements and maximum velocities. Further, closure duration was negatively related to the displacement and maximum velocity of the CV2 transition. Coproduction of vowels and consonants will be discussed.
