The acquisition of simple and complex coda /S/ in children with phonologic al disorder/Aquisicao da coda simples e complexa com /S/ em criancas com desvio fonologico

Purpose: to describe the production of final simple and complex coda with /S/ in children with phonological disorder, verifying the influence of linguistic and extra-linguistic variables in codas acquisition. Method: we utilized speech data from 66 children with phonological disorder, 33 boys and 33 girls, aged between 3:0 and 9:0. Speech samples were collected through a crossed-nature study, using the instrument referred to as Child Phonological Evaluation [1], with 481 words being part of the database from a project which was approved by the Ethics Research Committee (CEP) of the institution. Next, the words were statistically analyzed through the statistical program VARBRUL, considering a significance level of 5%. We took into account as dependent variables the correct production of /S/, the omission of the coda or its substitution. As intervening variable, we considered the extra-linguistic factors age, sex, degree of the phonological disorder; and the linguistic variables grammatical class, tonicity, precedent context, and type of coda. Results: the statistical program selected as statistically significant for the correct production of simple and complex coda, the degree of the phonological disorder, the type of coda, and the grammatical class, with the value of p < 0.01. Conclusion: we verified, through this study, that the degree of phonological disorder, type of coda, and grammatical class influenced in a significant way on the production of final simple and complex coda with the archiphoneme /S/, in children with phonological disorder. KEYWORDS: Speech Disorders; Speech; Child Language Objetivo: descrever a producao das codas finais simples e complexa com /S/ em criancas com desvio fonologico e verificar a influencia de variaveis linguisticas e extralinguisticas na aquisicao das mesmas. Metodo: foram utilizados dados de fala de 66 criancas com desvio fonologico, 33 meninos e 33 meninas, entre 3:0 e 9:0. As amostras de fala foram coletadas transversalmente, com base no instrumento Avaliacao Fonologica da Crianca. Foram analisadas apenas as palavras alvo contendo coda simples lexical (ex.: talvez), coda simples morfologica (ex.: casas), coda complexa composta por nasal e fricativa (ex.: parabens) e coda complexa com glide e fricativa (ex.: dois), totalizando um corpus de 481 palavras. Para ambos os tipos de coda foram consideradas como variaveis dependentes a producao correta do /S/, a omissao da coda ou sua substituicao. Como variaveis intervenient
