Timing effects on articulatory organization
Katherine Safford Harris, Thomas E. Baer · The Journal of the Acoustical Society of America · 1977
A simple model of timing control suggests that the commands for articulatory movements are the same for different speaking rates, and different stresses, but that their temporal spacing changes. The result of this change in temporal spacing is a change in articulatory target, due to the sluggishness of the articulators [B. Lindblom, J. Acoust. Soc. Am. 35, 1773–1781 (1963)]. A test of this hypothesis was made by comparison of acoustic signal, articulator movement measured by lateral view cineradiography, and EMG signals for a nonsense disyllable, produced with variable stress and speaking rate. Results suggest that commands it the articulators are reorganized under the various conditions. [Work supported by NINCDS grant NS 13870 and NIDR grant DE 01774.]
