Temporal characteristics in the fluent speech of child stutterers and nonstutterers

Past research reveals that adult stutterers often possess aberrant speech-timing abilities. As yet, only Healey and Adams (1981) have investigated these abilities in child stutterers. The present study attempted to assess the speech-timing skills of child stutterers and normal-speaking children while performing both simple and complex speech. Each subject was required to participate in two tasks: a sentence repetition task for simple speech and a story-retelling task for complex speech. Results supported those found by Healey and Adams, indicating that child stutterers have speech-timing abilities similar to normal-speaking children in simple speech tasks. The complex task, however, revealed that stutterers exhibited more frequent and longer interword pauses than nonstutterers. Two hypotheses generated from past research are offered to explain these differences. A third untested theory is also presented.
