“…Therefore, they have skills to identify their child's communication performance across a wide range of social contexts and are expected to provide a valid description of children's speech intelligibility (Hustad, 2012). To capitalize on parents' knowledge of children's functioning in context, McLeod, Harrison, and McCormack (2012) developed a parent questionnaire called Intelligibility in Context Scale (ICS). The ICS was designed to obtain parents' opinions about their child's speech intelligibility when talking to different communication partners.…”

The Intelligibility in Context Scale (ICS) is a parent report questionnaire for assessing children's speech intelligibility. The original version was developed in English and was based on Environmental Factors identified within the International Classification of Functioning, Disability and Health-Children and Youth Version (ICF-CY). The ICS has been translated into over 30 languages, including Traditional Chinese (ICS-TC). The aims of the current study were to examine the psychometric properties of the ICS-TC with Cantonese-speaking parent--child dyads and to identify speech measures that were more sensitive to the ICS-TC ratings. A total of 72 Cantonese-speaking preschoolers with (n = 39) and without speech sound disorders (SSD; n = 33) were recruited. Native Cantonese-speaking parents completed the ICS-TC independently. The measure showed good internal consistency and test-retest reliability. Correlations with speech performance on the Hong Kong Cantonese Articulation Test (HKCAT), and significant difference in ICS-TC mean scores between the two groups provided preliminary support for the validity of ICS-TC and suggested that ICS-TC can differentiate between children with and without SSD with a large effect size of d = 0.74. The optimal cutoff was estimated using Receiver Operative Characteristic (ROC) curve analysis, giving a sensitivity of 0.70 and specificity of 0.59. ICS-TC mean scores showed a positive correlation with the percentage of initial consonants correct and negative correlation with frequency of atypical errors, and both were moderate in strength. Given the satisfactory psychometric properties of ICS-TC, it may be a valuable clinical tool for screening Cantonese-speaking preschool children's intelligibility.

“…For the children from the other age groups, which present more stable productions, the following method for reliability between transcriptions was used: all samples were transcribed by an experienced evaluator in child language and a second evaluator with the same experience transcribed, independently, 20% of the same sample for reliability (5,17) . There was a mean agreement of 79.6% at the 3-yr age groups; 81.9% for 4-yr groups; and 80.1% for 5-yr groups.…”

RESUMO Objetivo Verificar as possíveis correlações entre o número de tipos lexicais e o número de consoantes no sistema fonológico geral em crianças com desenvolvimento típico de linguagem. Métodos 186 crianças entre um ano e seis meses e cinco anos, 11 meses e 29 dias, falantes monolíngues do Português Brasileiro, com desenvolvimento típico de linguagem, participaram do estudo. A coleta de dados envolveu avaliações fonoaudiológicas e gravação da fala espontânea. Analisou-se a fonologia quanto ao número de consoantes adquiridas no sistema fonológico geral, em cada estrutura silábica e nos níveis do Modelo Implicacional de Complexidade de Traços (MICT). O vocabulário foi analisado quanto ao número de tipos de itens lexicais produzidos. Estes dados foram comparados entre as faixas etárias. A seguir, foram analisadas as correlações entre os tipos lexicais produzidos e as variáveis estabelecidas para o sistema fonológico. O nível de significância adotado foi de 5%. Resultados Todos os aspectos da fonologia avaliados apresentaram crescimento gradual. Os tipos lexicais apresentaram comportamento semelhante, porém com uma pequena regressão na idade de cinco anos. Houve diferentes correlações positivas entre os tipos lexicais produzidos e as variáveis analisadas no sistema fonológico. Houve apenas uma correlação negativa, referente à produção dos tipos lexicais com o onset complexo na última faixa etária analisada. Conclusão A fonologia e o vocabulário apresentam comportamentos semelhantes. Há diversas correlações positivas entre os tipos lexicais produzidos e diferentes aspectos da fonologia, exceto em relação ao onset complexo.

Purpose: Describing the word classes and phonological classes' acquisition of the Brazilian Portuguese in children typically developed and verifying the correlations between these two language systems. Methods: In this study 186 children with typical language development, aged from 1 year, 6 months to 5 years, 11 months, who were Brazilian Portuguese speakers took part. The data collection involved speech, language and hearing assessments and spontaneous speech recordings. The production probabilities of each sound class were considered and the words produced were divided into word classes. The correlations among sound and word classes were analyzed. Results: Nasals and stops are the first sounds acquired followed by fricatives and liquids. Nouns and verbs are the first word classes produced. Regarding to statistically significant correlations, stops were positively correlated with nouns, adjectives, adverbs and pronouns. Fricatives had a lot of positive and negative correlations with different word classes. Liquids had positive correlations with adjectives and articles; and negative correlations with nouns, adverbs and numerals. No correlation was found among nasals and the sound classes. Conclusion: The acquisition of stops and nasals are precocious. The fricatives and liquids are more complex. Nouns and verbs are prevalent in the beginning of acquisition. The elements mostly related to syntax are acquired later. There are many correlations between phonology and vocabulary, showing a clear relationship between one another.

Métodos: O presente estudo contou com 186 crianças com desenvolvimento típico de linguagem, com idades entre 1 ano e 6 meses e 5 anos e 11 meses, falantes de Português Brasileiro. A coleta de dados envolveu avaliações fonoaudiológicas e gravações da fala espontânea. Considerou-se a probabilidade de produção de cada classe fonêmica e as palavras produzidas foram divididas em classes gramaticais. Após, buscou-se estabelecer as correlações entre essas classes. Resultados: Nasais e plosivas foram os primeiros sons adquiridos, seguidos pelas fricativas e líquidas. Substantivos e verbos foram as primeiras classes gramaticais produzidas. Em relação às correlações estatisticamente significantes, as plosivas tiveram correlação positiva com substantivos, adjetivos, advérbios e pronomes. As fricativas apresentaram várias correlações positivas e negativas com diferentes classes gramaticais. As líquidas tiveram correlações positivas com adjetivos e artigos e correlações negativas com substantivos, advér-bios e numerais. Não foram encontradas correlações entre as nasais e as classes gramaticais. Conclusão: A aquisição das plosivas e das nasais é precoce. Já as fricativas e líquidas, são mais complexas. Substantivos e verbos são...

The Intelligibility in Context Scale: Validity and Reliability of a Subjective Rating Measure

Abstract: The ICS is a promising new measure of functional intelligibility. These data provide initial support for the ICS as an easily administered, valid, and reliable estimate of preschool children's intelligibility when speaking with people of varying levels of familiarity and authority.
