Thirty-six children (17 with and 19 without SSD; average age = 6;7) participated in an adapted syllable identification test. The auditory and visual stimuli consisted of monosyllabic consonant-vowel utterances involving [p,b,t,d,k,g,f,v,s,z,ʃ,ʒ,m,n,ɲ,l,ʎ,ɾ,χ,w], produced in the context of [a] vowel. The stimuli were presented in different modality conditions: auditory-only (A_O), visual-only (V_O), audio-visual congruent (AV₊), and audio-visual incongruent (AV-). As expected, children with SSD showed lower perceptual accuracy than TD children across all modalities (A_O, V_O, and AV₊), indicating that their difficulties are not restricted to the visual domain. The prediction that SSD children would show reduced audiovisual integration was not confirmed. No differences were observed between groups in terms of visual gain from congruent audiovisual stimuli or susceptibility to the McGurk illusion, although both groups exhibited the effect. Exploratory analyses revealed that age accounts for part of the group differences, particularly in the V_O condition, while differences in A_O and AV₊ remained partially independent of age. Within the SSD group, PCC-R showed no significant multivariate effect, although univariate results indicated positive associations with A_O and AV₊, but not V_O. Although SSD children show reduced accuracy in speech perception across sensory modalities, audiovisual speech integration appears preserved. The variability observed within the SSD group suggests a complex and heterogeneous developmental profile that cannot be fully explained by age or severity, underscoring the need for integrated and individualised intervention approaches.</p>","PeriodicalId":49219,"journal":{"name":"Clinical Linguistics & Phonetics","volume":" ","pages":"1-16"},"PeriodicalIF":1.1,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148320348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More recently, teaching in this area has drawn on innovative approaches to support such practice, with increasing attention to game-based and playful learning. Contributing to this emerging field, this paper presents a set of playful, low-cost learning activities designed to support first-year students in developing core phonetic and phonological knowledge. Grounded in principles of playful learning, the activities create an open, low-stakes environment that encourages exploration, collaboration and productive failure. Examples include black-out poetry tasks that reinforce the distinction between letters and sounds and IPA-adapted word games such as word searches and IPA Scrabble.

While it is documented that compressed vowel space is often associated with low intelligibility, few studies have examined how acoustic vowel space changes during speech enrichment interventions are related to functional intelligibility gains. This study investigated whether change in acoustic vowel space can predict intelligibility improvement in DS. Thirteen children with DS completed a naturalistic speech enrichment intervention and were included in the present analysis. Vowel productions from a structured /hVt/ word task were acoustically analysed at baseline and post-speech enrichment interventions. To measure vowel space change, three metrics were used: articulatory-acoustic vowel space (AAVS), quadrilateral vowel space area (qVSA), and convex hull vowel space area (VSAhull). Intelligibility gains were measured using Growth Scale Values (GSVs) from the Woodcock Camarata Articulation Battery (WCAB). Regression analysis results revealed that changes in AAVS and VSAhull significantly predicted WCAB gains, while qVSA did not. These findings suggest that vowel space change reflects clinically meaningful articulatory adjustments, as indicated by their predictive association with intelligibility improvement following speech enrichment interventions. The lack of predictive power for qVSA highlights limitations of traditional corner-vowel metrics and supports the use of more comprehensive vowel space measures. While preliminary, these findings suggest that vowel space metrics may have future potential for clinical monitoring of speech development in children with DS, pending further validation in larger and more controlled studies.</p>","PeriodicalId":49219,"journal":{"name":"Clinical Linguistics & Phonetics","volume":" ","pages":"761-781"},"PeriodicalIF":1.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12959749/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146031258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the identification task, the participants were asked to choose between two alternatives of pseudowords, the one that corresponds to a conventional inflection in the language, based on the instruction they hear. In the production task, the participants were asked to produce an appropriate pronunciation of the pseudowords according to the requested inflection, without selecting from given alternatives.

The use of low-cost language biomarkers is becoming an emerging trend. This study aims to investigate whether recently proposed measures in the field of Quantitative Syntax and their combinations have the potential to serve as biomarkers for distinguishing between the MCI and cognitively normal (CN) groups. A portion of the Chinese corpus MCGD (CN = 25, MCI = 16) was used. The elderly participants performed a sequential picture description task to produce connected speech. The transcription and annotation were semi-automatically conducted and manually checked. Eleven dependency-based syntactic features were calculated. We assessed the discriminability of both univariate features and multivariate feature combinations using support vector machine. Results show that all features can be grouped into four clusters. Most measures within the largest cluster demonstrate high intercorrelations and are statistically significant in distinguishing between the MCI and CN groups. Among these, mean dependency distance (MDD) exhibits the strongest discriminative ability (AUC = 0.791 [0.610, 0.944]). Two hierarchical features have relatively weaker performance, while dependency direction indicators show almost no group differentiability. Several feature combinations identified slightly improved performance, but the difference was not statistically significant. Our findings suggest that the classic syntactic biomarker MDD remains the best-performing measure for distinguishing between MCI and CN for Mandarin-speaking older adults, while most dependency-based syntactic measures can serve as alternative markers.

One hundred and twenty-nine 4-9-year-old typically developing Cypriot-Greek-speaking children were recruited for the study.

The results showed that there were developmental changes in three measures of syntactic productivity (number of C-units and total number of words) and lexical diversity (number of different words). On the contrary, measures of syntactic complexity (MLU-word, number of subordinate clauses and mean of the five longest sentences) did not significantly differentiate children between the three groups. In addition, the results showed no significant gender effect on narrative skills.
