Interarticulator Timing Relations Underlie the Production of Precise and Consistent Vocal Tract Constrictions During Speech.

ABSTRACT:

Purpose

During speech production, complex patterns of coordinated movements between sets of articulators (e.g., jaw and tongue, jaw and lips) form precise and consistent constrictions at distinct locations along the vocal tract, despite rampant contextual variation. Speech motor control research seeks to uncover basic principles of organization governing interarticulator coordination during constriction formation, assuming many degrees of freedom for controlling articulator movements. This study tested the hypothesis that the motor system reduces degrees of freedom and facilitates coordination by reliably controlling interarticulator timing.

Method

Ten talkers produced vowel-consonant-vowel (VCV) sequences, recorded using electromagnetic articulography, with variation in pro
