| Abstract | [Introduction] In this chapter, we present some recent experimental and simulation results within a dynamical systems framework and describe their implications for issues in laboratory phonology. The experimental work entails application of phase-resetting techniques in which mechanical perturbations are delivered to the articulators during speaking, and the resultant changes in the utterance’s temporal structure are analyzed. This work is a subset of a more extensive data set described elsewhere (Saltzman, Lofqvist, Kay, Kinsella-Shaw & Rubin in press). These data are used to compare the degrees of cohesion among speech gestures-the strength of intergestural ‘glue’-both within and between traditional segmental units of articulation. Following the description of these experimental results, we address preliminary simulation work that focuses on how linguistically conditioned modulations of speaking rate might be modeled within the task-dynamic model of gestural patterning (Saltzman & Munhall 1989). We describe the results of implementing a simple ‘clocking’ mechanism, and briefly review its implications for interpreting temporal variations in the articulation of syllable-sized units of speech. |
