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.

Auditory Feedback Control

AbstractAccurate and fluent production of speech strongly depends on hearing oneself which allows for the detection and correction of vocalization errors in real-time. When auditory feedback is disrupted with a time delay (e.g. echo on a conference call), it causes slowed and stutter-like speech in humans. Impaired speech motor control during delayed auditory feedback is implicated in various neurological disorders ranging from stuttering to aphasia, however the underlying neural mechanisms are poorly understood. Here, we investigated auditory feedback control in human speech by obtaining electrocorticographic recordings from neurosurgical subjects performing a delayed auditory feedback (DAF) task. We observed a significant increase in neural activity in auditory sites that scaled with the duration of feedback delay and correlated with response suppression during normal speech, providing direct evidence for a shared mechanism between sensitivity to altered feedback and speech-induced auditory suppression in humans. Furthermore, we find that when subjects robustly slowed down their speech rate to compensate for the delay, the dorsal division of the precentral gyrus was preferentially recruited to support articulation during an early time frame. This recruitment was accompanied by response enhancement across a large speech network commencing in temporal cortex and then engaging frontal and parietal sites. Our results highlight the critical components of the human speech network that support auditory feedback control of speech production and the temporal evolution of their recruitment.

Vocal Intensity

In this case study, a 59-year-old male with progressive supranuclear palsy and hypokinetic dysarthria wore a small, solid state, battery operated, delayed auditory feedback device to reduce speech rate and to aid speech intelligibility. Time series measurements were made from tape recordings taken at the beginning of treatment and again after three months of daily wearing of the device. Measures of speech rate, intensity, and overall intelligibility indicate that when the instrument is worn, the subject's speech is slowed, vocal intensity increases, and intelligibility is markedly improved. The subject and his family report satisfaction with the instrument. The application of delayed auditory feedback to the treatment of communication disorders is discussed.

ABSTRACT Objective: to describe the immediate effects of delayed auditory feedback on stuttering-like disfluencies in people who stutter. Methods: a cross-sectional and experimental study. The effect of delayed auditory feedback was analyzed in thirty individuals, from eight to 46 years old, diagnosed with persistent developmental stuttering. Participants should present at least 3% of stuttering-like disfluencies and mild stuttering according to the Stuttering Severity Instrument. The following procedures were used: audiological evaluation, fluency evaluation in two listening situations - with Non-altered and delayed auditory feedback - and the Stuttering Severity Instrument. The Fono Tools software was used to cause the delay effect. Data analysis was performed using pertinent statistical tests. Results: there was no decrease in most stuttering-like disfluencies. There was a statistically significant reduction in word repetition and flow of syllables per minute. Conclusion: the delay in auditory feedback caused, as an immediate effect, the reduction of word repetition and speech rate, in syllables per minute.
