Laryngeal Behavior During Stuttering

Abstract

Laryngeal behavior associated with 101 stutterings (part-work repetitions, sound prolongations, and broken words) produced by a group of 10 stutterers was observed by means of a flexible fiberoptic naso-laryngoscope. Results indicated that 60% of part-word repetitions were different from fluent productions of the same speech segment in terms of laryngeal behavior, and 72% of sound prolongations were similar to fluent productions of the same speech segment. Findings indicate that there are differences in laryngeal behavior among the various types of stutterings.
