Active Inhibition

Craig discussed fluency outcomes following stuttering therapy that involved retraining the speech system, on the assumption that the speech end product is truly fluent. As previously outlined by Dayalu and Kalinowski, we strongly disagree with the notion that behavioral paradigms can ever result in automatic, long lasting natural sounding fluent speech. Fluent speech is within the grasp of one who stutters as seen in the effects of choral speech and derivatives such as delayed auditory feedback.

Clinical Program

Operant speech fluency techniques are being used in a clinical program in a rehabilitation center to treat people who stutter. Establishment, transfer, and maintenance programs are used. Delayed auditory feedback is commonly employed to produce the initial fluent speech. From more than 200 clients seen over the past four years, 50 recent clients were selected for a detailed analysis. The results indicate that the programs are effective in helping people of varying ages and stuttering severity to speak fluently. This was accomplished in relatively short periods (approximately 20 hours of therapy). The fluent speech of the clients has transferred to their environment and checks indicate that it has been maintained.

Puzzle Solving

In 1970 Kuhn argued that science does not progress through a process of accretion. It is typified, rather, by the successive emergence of different paradigms which during their reign dictate the direction of normal science's puzzle-solving activity. Normal science inevitably exposes an anomaly which violates expectations predicted by the reigning paradigm. The “crisis” evoking anomaly may induce a destructive/constructive paradigm change. Transformations from one paradigm to another constitute a scientific revolution and dictate the growth and maturation of a field. This paper suggests the recent finding, that stutterers experience enhancement of fluency while speaking under delayed auditory feedback at a fast articulatory rate, be viewed as an anomaly. By challenging the notion that a slowed speech rate is necessary for amelioration of stuttering, the anomalous finding may be perceived as a crisis in the study of stuttering.

Fluent Speech

This report concerns operant stuttering therapy programs for five children ranging in age from six to nine years. The programs included programmed desensitization, delayed auditory feedback, and gradual increase in the length and complexity of the speech utterance. Reinforcing events ranged from social reward to points which could be exchanged for toys. The programs varied in length from 15 to 73.3 hours. They were all successful in helping the children to establish fluent speech. Special transfer and maintenance programs were necessary for some of the children. Follow-up measures indicated that the children had maintained their fluency. The value of viewing stuttering as operant behavior was demonstrated.

Masking Noise

Measurements were made of the formant frequencies and formant transitions associated with the vowels/i/,/æ/ and /u/ produced by seven moderate-to-severe stutterers when they read fluently in a control (normal) condition and under four experimental conditions: masking noise, delayed auditory feedback, rhythmic pacing, and whispering. The first and second formantfrequencies in an isolated/hVd/context were more centralized than those reported for nonstutterers. The formant frequencies were centralized even more in reading, but varied little across conditions despite changes in fluency, speaking rates, and vowel duration. Duration and rate of formant transitions also were essentially the same across conditions. These findings and those reported in other studies indicate that stutterers' vowel production is more restricted, spatially and temporally, than nonstutterers'.

Binaurally asynchronous delayed auditory feedback (DAF) was compared with synchronous DAF in 80 normal subjects. Asynchronous DAF (0.10 sec difference) did not yield results different from those obtained under synchronous DAF with a 0.20 sec delay interval, an interval characteristically resulting in maximum disruptions in speech.
