Duration of sound prolongation and sound/syllable repetition in children who stutter: preliminary observations.
The purpose of this study was to measure the duration of sound prolongations and sound/syllable repetitions (stutterings) in the conversational speech of school-age children who stutter. The relationships between duration and (a) frequency and type of speech disfluency, (b) number and rate of repeated units per instance of sound/syllable repetition, (c) overall speech rate, and (d) articulatory rate were also examined. Results indicated that for the children in this study the average duration of stuttering was approximately three-quarters of a second, and was not significantly correlated with age, length of post-onset interval, or frequency of speech disfluency. In addition, findings can be taken to suggest that part of the clinical significance of stuttering duration for children who stutter might lie in its relationship to the amount of sound prolongations these children produce, as well as their articulatory rate during fluent speech.
