Purpose: The purpose of this clinical focus article is to summarize 1 possible process that a clinician might follow in designing and conducting a treatment program with John, a 14-year-old male individual who stutters. Method: The available research evidence, practitioner experience, and consideration of individual preferences are combined to…

This study, involving an adolescent and adult male with stuttering problems, evaluated modification of the frequency of electroglottograph-measured phonation intervals on stuttering and speech naturalness. Both subjects demonstrated that stuttering could be controlled by modifying the frequency of phonation intervals within short duration ranges,…

Purpose: Previous research has demonstrated the fluency-improving effect of reducing the occurrence of short-duration, phonated intervals (PIs; approximately 30-150 ms) in individuals who stutter, prompting the hypothesis that PIs in these individuals' speech are not distributed normally, particularly in the short PI ranges. It has also been…
