[Severity of phonological disorders: perceptual judgment and percentage of correct consonants]. / Gravidade do disttúrbio fonológico: julgamento perceptivo e porcentagem de consoantes corretas.

ABSTRACT

BACKGROUND: Phonological disorder. AIM: To apply the percentage of correct consonant (PCC) index and to verify the correlation between this index and the one applied perceptually by judges. METHOD: The PCC index of 50 phonological disordered subjects was calculated, after 60 judges heard the phonological tests for each subject and perceptually attributed the severity. RESULTS: The PCC index varied from 40% to 98%, with the predominant classification of the population in the mild and mild-moderate levels. CONCLUSION: A correlation between the perceptual judgment and the PCC indexes exists.
