“…In contrast, no significant difference was observed in PVC. This finding was consistent with the study conducted by Bernhardt [10] et al, and Zarifian et al [28]. James believed that the PCC median values increase with age, which was consistent with the present study, but the increase in the PVC with age in James' research [5] was not confirmed in this study.…”

“…Also, the test should allow common error patterns of the target language to appear. Among the common error patterns in the Persian language [28], cluster reduction, final consonant deletion, assimilation, voicing, and syllable deletion were frequently seen in the production of children in this study. Baker et al's test [3] has such a feature among the international studies.…”

“…A review of literature in other languages showed that although children usually achieve the correct production of vowels by the age of three [19] and the correct production of consonants correctly by the age of four, incorrect articulation of acquired sounds in polysyllabic words continues until older age [7]. Zarifian and Fotuhi reported that Persian-speaking children master all vowels before age three, but consonant mastery extends up to four years and six months [20]. However, the phonetic test used in this study included only a small number of polysyllabic words.…”

Objective Reviewing the literature related to the use of polysyllabic words in the assessment of speech sound disorders (SSD) in children have indicated the necessity of using these words for providing additional information such as prognostic information. Despite strong literature in other languages, there is scant research on examining the production of these words in the Persian language among children aged 4-7 years. Therefore, this study aims to design and assess the psychometric properties of the Persian version of the polysyllabic words test (PWT) for measuring production skills in Iranian preschool children. Materials & MethodsIn this cross-sectional study, First, 532 polysyllabic words with 3, 4, 5, and 6 syllables were selected from preschool children's books, which was reduced to 66 words after agreement among authors in three rounds. The content validity of the items was examined according to the opinions of five experts in typical speech development and SSD in terms of four criteria: Appropriateness for producing polysyllabic words, appropriateness for children aged 4-7 years, imageability, and cultural fit. After selecting pictures, face validity of items was examined by implementing the test on eight 4-7-year-old children (at least one child from each age group). Finally, 40 items were considered as the final words of PWT. For measuring psychometric properties, 120 children with normal development (60 males, 60 females), and 20 children with SSD (10 males, 10 females) participated. The control children were divided into 6 age groups with a 6-month interval (10 males and 10 females in each age group). Their inclusion criteria were age 4-7 years, not being bilingual, and passing the Persian diagnostic evaluation of articulation and phonology test (DEAP; Zarifian, 2014) and informal language screening test successfully. Because of the COVID-19 pandemic and the closure of most schools, the sampling of control children was done using a convenience method from two cities (Tehran and Karaj). The inclusion criteria for SSD children were: Inability to pass the DEAP test, not being bilingual, and having SSD. Their sampling was also done using a convenience method. For evaluating construct validity, the differences among six age groups, between males and females, and between control and SSD children were examined in terms of total score, percent consonants correct (PCC), percent vowels correct (PVC), and percent phonemes correct (PPC). Test-retest reliability was determined using 20 children at a one-week interval, and interrater reliability was determined by investigation of relations between scores of two independent raters for 20 children using the intra-class correlation coefficient (ICC). The internal consistency was determined by measuring the Cronbach's alpha coefficient. Descriptive statistics, ANOVA, independent t-test, Tuckey's post hoc test, were used for data analysis in SPSS software, version 26. Results In comparing the age groups, the results showed a significant difference in terms of total sc...

“…To achieve this goal, it was necessary to collect data including ratings of pronunciation by human expert evaluators to test the validity of this type of assessment algorithm or system. For reliability assessment, it usually means that the scores obtained by the same test-taker after taking the same test under different test conditions are consistent or highly correlated [10]. Device sensing technology can be divided into five basic categories: vector pressure sensing technology touch screen, resistive technology touch screen, capacitive technology touch screen, infrared technology touch screen, and surface acoustic wave technology touch screen.…”

In this paper, a multimodal intelligent acoustic sensor is used for an in-depth study and analysis of English pronunciation signal acquisition and calibration analysis of English phonetic symbols based on the acquired sound signals. This paper proposes a bimodal fusion algorithm around the direction of feature extension and fusion of acoustic recognition features. After each unimodal classification error cost is minimized, the current fusion process is determined by adaptive weights to fix its one decision layer on the fusion. The adaptive weight approach in this algorithm improves the drawback of always identifying one mode as the optimal mode in fixed-weight fusion and further improves applicability and performance compared to unimodal recognition. The random network generation algorithm is used to generate a random network for sound source data acquisition; then, the algorithm is investigated using the decomposition containing fusion center algorithm to each node, and data preprocessing is implemented at each node; finally, the distributed consistency algorithm based on average weights is used for consistent averaging iterations to achieve a consistent speech enhancement effect at each node. The experimental results show that this distributed algorithm can effectively suppress the interference of noncoherent noise, and each node can obtain an enhanced signal close to the source signal-to-noise ratio. In this study, factors that may affect the readability of spoken texts are summarized, analyzed, defined, and extracted, and the difficulty of spoken items obtained from the divisional scoring model is used as the dependent variable, and the extracted influencing factors are used as independent variables for feature screening, model construction, and tuning, and the generated results are interpreted and analyzed. From this, it was found that phonological features have a strong influence on the readability of spoken texts, mainly in features such as phonemes, syllables, and stress. This study is summarized, and the shortcomings of location-based contextual mobile learning of spoken English in terms of student management, device deployment, and empirical evidence are pointed out, to provide references and lessons for the research on IT-supported language learning.

RESUMO Objetivo Caracterizar o uso de processos fonológicos produtivos no grupo de crianças nascidas a termo e pequenas para a idade gestacional e compará-lo com crianças adequadas para a idade gestacional. Método Estudo observacional, analítico, do tipo caso-controle, não pareado, aninhado a uma coorte com o desfecho alteração fonológica. Foram avaliadas 36 crianças de acordo com o cálculo amostral pré-estabelecido, sendo 24(66,7%) sem alterações fonológicas e 12(33,3) com alteração fonológica. Dessas, 24(66,7%) crianças foram classificadas como pequeno para a idade gestacional (PIG) e 12(33%), como adequada para a idade gestacional (AIG). Os aspectos fonológicos da linguagem oral foram avaliados pelo teste de linguagem infantil ABFW (2004). Os resultados foram submetidos à análise descritiva e a fim de avaliar a existência de associação entre as variáveis categóricas, foi utilizado o teste exato de Fisher de associação. Resultados O grupo PIG apresentou significativamente maior número de processos fonológicos que alteram a estrutura da sílaba quando comparado ao grupo AIG. Observou-se que os processos fonológicos presentes e não esperados para idade na população PIG foram: plosivação de fricativa, simplificação de líquidas, posteriorização e frontalização de palatal, ensurdecimento de plosivas e fricativas, além da simplificação do encontro consonantal e simplificação de consoante final, que foram os de maior ocorrência em ambos os grupos. Conclusão Embora não tenha sido encontrada associação entre alterações fonológicas e crianças PIG, observou-se maior uso de processos fonológicos produtivos neste grupo.
