Abstract

Objectives: Stuttering is one of the most common speech disorders that has a dynamic and multifactorial nature. The evidences suggest that auditory processing deficit may be involved in stuttering. It is not clear how the auditory system relates to stuttering and which aspect of the auditory processing disorder may be the cause of stuttering. This study aimed at presenting a comprehensive review of the literature to better explain the role of the auditory system and auditory processing disorder in stuttering. Methods: We searched the literature in Elsevier, PubMed, Scopus, and Web of knowledge, Google Scholar databases, Clinical trials, and Cochrane database of systematic reviews from 2000, through 2020. Published studies on the role of the auditory system in stuttering were reviewed. Results: In articles describing the aetiology of stuttering, auditory processing disorder, particularly temporal processing, has been considered as one of the causes of stuttering. Some researchers considered auditory temporal processing disorder as an intensifying and a sufficient factor for chronic stuttering. According to studies, it seems that auditory temporal processing disorder may affect stuttering by mechanisms such as disturbing the correct auditory feedback to brain speech control centres, instability in neural representations of speech sounds and the occurrence of sensory-motor inconsistencies in the speech control process. Conclusion: Based on studies, it can be concluded that auditory processing disorder may be one of the underlying or intensifying factors of stuttering. © 2022 International Association of Physicians in Audiology.
