The present study corresponds to a single subject design, analyzes the patterns of stuttering in the speech corpus in various oral language tasks, under the conditions of use or non-use of Delayed Auditory Feedback (DAF), in order to establish the effect of the DAF in the frequency of occurrence and type of dysrhythmia. The study concludes the positive effect of the DAF, with a rate of return of 25% on the errors of fluency, with variation depending on the type of oral production task. This in turn suggests that 75% of the disfluency or linked with top encode failures or not susceptible to resolve or compensated by the DAF. The authors discuss the implications of these fndings for therapeutic intervention in stuttering.
