Abstract
The human vocal mechanism has a singularity near the vowel /ee/. Investigating the role of redundant articulatory parameters in speech transitions near this singularity involves 1) applying curve-fitting methods developed for robot motion planning to the complete tongue outline, 2) calculating resonance frequencies from a geometric construction of streamline flow in a 2-d vocal tract, and 3) solving the inverse articulatory-to-acoustic transformation by optimization constrained by x-ray measures of pellet markers on the tongue, jaw, and lips. Time histories of articulatory parameters of the word /used/ from two subjects show an absence of compensation for the effect of the singularity on the shape of the formant transitions.1
