Relationship between Changes of Auditory Processing and Phonological Disorder

Introduction: The auditory information contains complex articulatory and acoustic aspects that need to be gathered from the children in the process of language acquisition.

Objective: To analyze the phonological evaluation data, from the samples of children with speech disorder, and the data found in the samples collected in auditory processing, identifying the subprofiles decoding, integration, output organization, association nonverbal function, in order to relate phonological disorder with auditory processing disorders.

Methodology: This a quantitative and descriptive study, with analysis of secondary data collected from the Database VALDEF (FAPERGS—Case no. 0904179 and CNPq—process no. 483886/2010-6). The database consists of 130 children, of whom 66 have auditory processing, which is the study sample.

Results: According to the results, 96.97% of the samples showed alterations in at least one subprofile auditory processing, and the only two subjects that did not showed changes were from the group with average degree of phonological disorders, representing 3.03%. Considering all degrees of phonological disorders, the subprofile that more change occurred was that of decoding, occurring in 100% of subjects with severe phonological disorders.

Conclusion: The results suggest a relationship between deficits in auditory processing and phonological disorders, mainly because all groups presented deficits decoding, which is related, among others, with the difficulties in discrimination of sounds and analysis of speech sounds.
