Abstract
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.
Highlights
Stuttering is a speech disorder notoriously characterized by syllable repetitions, prolongations, and blocks[1]
Based on the hypothesis that the type of disfluency may influence the effectiveness of delayed auditory feedback as an intervention in the treatment of stuttering, this study aimed to compare the immediate effects of delayed auditory feedback on the different typologies of stuttering-like disfluencies in individuals affected by the disorder
Individuals should: to be native speakers of Brazilian Portuguese; age between eight to 59 years and 11 months; to have normal hearing thresholds[22], to present a complaint of stuttering; the onset of the disorder should have occurred during childhood; disfluencies without remission; to present at least 3% of stuttering-like disfluencies[23], stuttering rated at least as mild according to the Stuttering Severity Instrument (SSI-3)[24] and never having experienced previously delayed auditory feedback
Summary
Stuttering is a speech disorder notoriously characterized by syllable repetitions, prolongations, and blocks[1]. These excessive stuttering-like disfluencies during the linguistic formulation of speech[2,3,4] impair smoothness[5] and the speech rate[6] during speech. Electrophysiological evidences have reinforced the hypothesis that stuttering is associated with a deficit in the modulation of the cortical auditory system during speech planning and that this may contribute to inefficient monitoring of auditory feedback and, result in speech disfluencies[11]
