Abstract

The aim of this study was to describe the performance of children with and without Phonological Disorder in severity, speech inconsistency, speech errors consistency and stimulability measures. There were evaluated 130 subjects of both genders and ages between 5:0 and 10:10 years, 55 with phonological disorder and 75 without phonological alterations. Most of children with phonological disorder were stimulable for absent sounds of phonetic inventory showing difficulties in applying them to communicative situations. It was confirmed gender and age effects and established four cut-off values for speech inconsistency. Speech inconsistency was efficient to evaluate phonological programming and stimulability the motor production. Results suggested that the phonological programming is refined each year of life of children and occur differently between genders. The motor speech production showed similarity between boys and girls. The two measures studied were effective in differentiating children eith and eithout phonological disorders as well as contributing to the identification of difficulties of children showing that they are complementary and essential to detect diagnostic markers of phonological disorders.
