Analysis of Results of the Speech Recognition Percentage Index in Children with Phonological Disorder

The speech recognition percentage index (SRPI) is capable of measuring speech intelligibility in a fixed intensity in which the individual can repeat as many words as possible. It is known that 90 to 100% have normal bounds; however, from 90% these limits are reduced, impairing speech understanding. The phonological disorder, specific language impairment, cause mental disorder representation of speech sounds and your diagnosis includes the absence of hearing loss. The objective of this study is to analyze the results of the SRPI in relation to degree of phonological disorder of 76 children between 5 and 10 years. This is a quantitative and descriptive survey, with secondary data analysis collected from the VALDEF - database composed for speech-language-hearing assessments of 130 children with phonological disorder - (FAPERGS-process no. 0904179 and CNPq-process no. 483886/2010-6). To characterize the results, were made assessment the percentage of SRPI through speech audiometry, in monosyllables, in relation of the diagnosis of the degree of deviation. Although all individuals have normal thresholds of hearing, 12% presented results of SPRI downgraded by at least one of the ears. To occur, the perfect auditory discrimination is necessary for the child to realize the acoustic difference of phonemes, which will allow the typical phonological acquisition. A small percentage of individuals who had downgraded results can be interpreted as a limitation of this research, demonstrating the need for further studies with a larger sample, in order to find significant data linking the SRPI and phonological disorders.
