Why does stuttering disappear when one’s own speech is not heard? External and internal auditory feedback and their impact on stuttering. (2020)

Neurological findings suggest that auditory feedback is used in speech control less effectively by individuals who stutter, as compared with normally fluent speakers; therefore, insufficient auditory-motor integration has been hypothesized to be a causal factor in stuttering. On the other hand, people who stutter are usually fluent when they do not hear themselves speak. This suggests that auditory feedback is irrelevant for speech control and even harmful for individuals who stutter. The present paper proposes an explanation for these seemingly conflicting observations.
It is assumed that speech feedback in the auditory modality is necessary for the control of fluent speech. When no external auditory feedback is available, e.g., because of masking by noise, speech control shifts to an internal feedback loop that provides predictions of the auditory consequences of speech motor commands to the speech comprehension system. In this way, one’s own speech is heard internally. The use of this internal ‘auditory’ feedback saves from stuttering because of a close coupling between speech production and speech perception. However, the internal feedback loop works only if no external auditory feedback is available. Therefore, the internal feedback loop cannot compensate for insufficient integration of external auditory feedback in normal conditions, i.e., when one’s own voice is heard during speech.
Therefore, the hypothesis that insufficient integration of auditory feedback is a causal factor in developmental stuttering is consistent with the fact that stuttering disappears when one’s own speech is not heard. Article length: 12 pages plus references
