“…This result differs from another study 20 , which investigated the phonemic discrimination of all phonemes of BP, also in children with phonological disorders. Those authors also suggested a possible causal relation between an inability of auditory discrimination and phonological disorders that, however, did not apply to all cases they assessed.…”

O contraste de sonoridade das plosivas representa uma complexa coordenação acústica e articulatória, muitas vezes prejudicada nos desvios fonológicos. Por esse motivo, acredita-se que esforços devem ser realizados no sentido de melhor entender os fatores que influenciam na estabilização desse contraste. Assim, o objetivo desta pesquisa foi correlacionar os dados de produção e o desempenho em um teste de discriminação do traço [+voz] em crianças com desvio fonológico. Para isso foram avaliados cinco meninos com desvio fonológico e dificuldade na produção das plosivas sonoras, entre outras dificuldades de fala. Por meio de pares de palavras inseridos em frase-veículo, observou-se a ocorrência de produção de Voice Onset Time positivo durante a produção de plosivas [+voz] e o padrão de duração das vogais adjacentes às plosivas surdas e sonoras. Elaborou-se um Teste de Discriminação de Sonoridade das Plosivas, a fim de se avaliar o desempenho dos sujeitos em relação à discriminação. O teste consiste de 12 pares de palavras, diferenciados apenas pelo contraste [+voz] e representados por figuras. Na análise descritiva, não se verificou uma relação direta entre dificuldade de produção do contraste de sonoridade das plosivas e discriminação auditiva desses segmentos, tanto na observação da produção de pré-sonoridade, quanto na observação da produção do padrão de duração das vogais. Mesmo assim, salienta-se que o emprego de uma avaliação de discriminação, bem como, de análise acústica nos casos de desvio fonológico, não devem ser desprezados pelos fonoaudiólogos, uma vez que esses instrumentos podem fornecer informações fundamentais para um bom progresso terapêutico.

“…Therefore, it is the individual's ability to perceive minimum acoustic differences present in the discourse (2,3) , and it is considered as a key aspect for the correct production of speech sounds -the mental representation and storage of linguistic stimuli are established through reception, analysis, and organization of information by auditory processing (1)(2)(3)(4)(5) . Therefore, the ability to discriminate phonemes is critical to the beginning of this process and for phonological acquisition (3) .…”

“…For the acquisition of speech sounds, it is essential that the ability to perceive minor differences between the distinctive features that occur by binary oppositions is established. These are described with values for the following combinations: [ (5) . Therefore, conditions are necessary so that these sounds are discriminated (6) , such as the integrity of organic structures involved in the detection, reception, and conduction of sound, as well as interpretation processes, so that the sound is perceived (7) .…”

Discriminação fonêmica e a relação com os demais níveis linguísticos em crianças com desenvolvimento fonológico típico e com desvio fonológico evolutivoABSTRACT Purpose: To compare children with typical language development (TLD) and evolutional phonological disorder (EPD) regarding the phonemic discrimination and the linguistic performance of language levels (morphological, syntactic, semantic, and perceptual and productive vocabulary). Methods: The sample comprised 36 children, aged between 5 years and 7 years and 11 months, with TLD and EPD. Children with EPD were awaiting care in the speech units of two higher education institutions and children with TLD were screened in public schools. For inclusion in the study, the criteria were the following: being authorized by the informed consent and being within the required age group. After the inclusion of children, all subjects underwent the phonemic discrimination test with figures, to the average phrase value test, which assesses the morphosyntactic and semantic/lexical aspects, and the expressive vocabulary test. For statistical evaluation of the influence of variables, Spearman's nonparametric correlation coefficient was used, and for comparison between the groups regarding evaluation performance, Mann-Whitney test was used. Results: Only children with EPD showed influence of phonemic discrimination in other linguistic levels. In addition, a significant difference was observed between the performances of both groups in relation to the phonemic discrimination, vocabulary, and all levels assessed in the questions and description modality. Conclusion: The comparison between both groups showed a statistically significant difference in phonemic discrimination and morphosyntactic and lexical/semantic development, with better performance in the TLD group. RESUMOObjetivo: Comparar crianças com desenvolvimento típico de linguagem (DTL) e com desvio fonológico evolutivo (DFE) quanto à discriminação fonêmica e ao desempenho linguístico dos níveis da linguagem (morfológico, sintático, semântico e vocabulários perceptivo e produtivo). Métodos: A amostra foi constituída por 36 crianças, com idades de5a 7 anos e 11 meses e com DTL e com DFE. As crianças com DFE aguardavam atendimento nos setores de fala de duas Instituições de Ensino Superior (IES) e as crianças com DTL foram triadas em escolas públicas. Para a inclusão na pesquisa, os critérios foram: autorização pelo Termo de Consentimento Livre e Esclarecido (TCLE), ter a idade estipulada e ter DTL. Após a inclusão das crianças, todos os sujeitos foram submetidos ao teste de figuras para discriminação fonêmica (TFDF), ao teste média de valores de frases (MVF), que avalia os aspectos morfossintáticos e semânticos/lexicais, e ao teste de vocabulário expressivo (TVExp). Para avaliação estatística da influência das variáveis, foi realizado o Study carried out at the Graduate Program in

Purpose The aim of this study was to conduct a systematic review and meta-analysis to investigate whether preschool- and early school–age children with speech sound disorders (SSDs) have difficulties with speech perception. Method Systematic searching of 8 electronic databases identified 73 eligible studies across 71 articles examining the speech perception skills of children with SSDs. The findings and methodological characteristics of each study were reviewed, and the reporting of methodological information in each article was rated. A meta-analysis was conducted with studies that used the most common type of speech perception assessment task—lexical and/or phonetic judgment tasks. Results Across 60 of 73 studies, some or all children with SSDs were reported to have difficulties with speech perception. The meta-analysis showed a significant difference between children with SSDs and children with typically developing speech on lexical and/or phonetic judgment tasks. Conclusion Results from the meta-analysis demonstrate that children with SSDs have difficulties with speech perception. This appears to be the case for some but not all children with SSDs. The findings from this systematic review and meta-analysis also provide insight into the complex range of methodological issues involved in the study of speech perception in children with SSDs and the need for further research.
