Purpose: English and Mandarin are the 2 most spoken languages in the world, yet it is not known how stuttering manifests in English-Mandarin bilinguals. In this research, the authors investigated whether the severity and type of stuttering is different in English and Mandarin in English-Mandarin bilinguals, and whether this difference was…

Background: It is widely known that most young children recover from stuttering. Evaluations of this spontaneous recovery vary from 40 to 80% of stuttering children. However, if the child is already older than 6 years of age, the spontaneous recovery will be less likely. The effectiveness of stuttering treatment, and especially fluency shaping…

High levels of anxiety can negatively affect the lives of children and adolescents. Thirty-six adolescents who stutter and 36 adolescents who do not stutter were administered standardized scales for anxiety and self-esteem. Significant differences were found for the total T-scores for "Revised Children's Manifest Anxiety Scale" for the two groups,…

Self-contained ear-level devices delivering altered auditory feedback (AAF) for the application with those who stutter have only been recently developed. The paper examines the first therapeutic application of self-contained ear-level devices in three experiments. The effect of the device on the proportion of stuttered syllables and speech…

Two studies illustrate the utility of listener ratings of speech naturalness for measuring and modifying speech naturalness during stuttering therapy. The program involved five adolescent stutterers receiving an intensive treatment incorporating a prolonged speech procedure. Results showed that speech naturalness ratings could be modified toward a…

Transcriptions of the speech of 16 adolescent and young adult stutterers and 16 nonstutterers were rated by 12 fourth and fifth year speech/language pathology students as a sample from a stutterer or a nonstutterer. (PHR)

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…

The case of a 15-year-old stutterer is presented to illustrate A. Lazarus's multimodal behavior therapy model, proposed to integrate various procedures. A combination of role playing, metronome use, biofeedback training, and assertion training was used. (CL)

Of 169 adult and adolescent stutterers studied, 112 reported family history of stuttering. Only 3 of the 112 reported birth or early childhood factors that might precipitate stuttering, as opposed to 21 of those without family history of stuttering. By considering these two conditions as separate factors in behavior, stutterers may be divided into…

Described is a procedure for the reduction of stuttering behavior by means of reality confrontations in structure verbal exchanges, which has been used by the author as treatment with over 200 adolescent stutterers. (Author/IM)

Fifty adolescent or young adult stutterers and nonstutterers cancelled the auditory sensation evoked by bone-conducted sinusoidal signals. (Author)

This study investigated whether syntactic complexity exerts an influence on the frequency of stuttering in the speech of seven adolescents who stuttered and seven who were normally fluent. Although normal disfluencies and errors in repetition accuracy increased as syntactic complexity increased, stuttering frequency did not appear to be affected…
