Acoustically controlled auditory training in children with speech disfluency: a case report

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

The purpose of this study was to verify the effect of the acoustically controlled auditory training on the speech fluency of children diagnosed with developmental stuttering. Two patients were submitted to speech fluency evaluation, basic audiological assessment, and central auditory processing assessment, before and after the intervention with the digital platform. Two male individuals (P1 and P2) participated in the research. They were respectively 8 and 9 years old, both were right-handed, native Brazilian Portuguese speakers, diagnosed with developmental stuttering, P1 presenting a moderate, and P2, a mild-to-moderate degree. There was an improvement in some auditory skills. However, there was no improvement in the speech fluency pattern in neither of the cases studied.
