Abstract

A study examining speech compensation in persons who stutter is presented. The underlying assumption is that if PWS are at the lower end of a speech motor skill continuum one should be able to find differences between PWS and PNS in tasks which tax their abilities to control their speech motor system. If delayed compensation is found in PNS with perfectly intact sensory-motor systems. Then one would expect that if PWS have speech motor skill limitations, they would compensate to a lesser degree and/or may take longer time to adapt to oral articulatory perturbations relative to PNS. Word and vowel duration measures provide an index of how task requirements relating to speech rate are implemented by PWS and PNS. The data also revealed that PWS may require additional time compared to PNS to adapt to perturbations.
