{"title":"Intrinsic fundamental frequency of vowels in children with Childhood Apraxia of Speech (CAS).","authors":"Hayo Terband, Bhavana Bhat","doi":"10.1159/000545595","DOIUrl":"https://doi.org/10.1159/000545595","url":null,"abstract":"<p><p>Background Intrinsic pitch (IF0) is an inherent property of vowels where high vowels are produced with a higher fundamental frequency than low vowels. Although well studied in adults, it remains underexplored in children. IF0 reflects combined biomechanical effects as well as a deliberate effort from speakers to produce distinct vowels and enhance vowel contrasts. Vowel errors and inconsistency in vowel production is one of the well-known characteristics in Childhood Apraxia of Speech (CAS). We aimed to investigate if children with CAS exhibit IF0 and if present, how it compares with typically developing (TD) children. Method 17 CAS children and 8 TD children were asked to repeat simple bisyllabic non-word utterances of the type [dəCV] six times. The stimuli contained a consonant, C (/b, d/) and a vowel V, which comprised of the corner vowels of the Dutch vowel space (/a, i, u/). The target stimulus was produced in a carrier sentence (/he dəCV wɪːr/; 'hey the CV again'). Mean pitch (F0) and formant (F1 to F3) values were extracted from the recorded speech samples around vowel midpoint and Bark transformed prior to further analyses. Statistical analyses were carried out using linear mixed models for each outcome measure separately. Results The main finding of our study is that IF0 is present in children with CAS with a pattern generally similar to TD children. Additionally, we observed differences in vowel characteristics in children with CAS that are ambiguous, rather we observed vowel specific differences. Children with CAS produced the /a/ vowel with an exaggerated openness whereas they produced /u/ more fronted compared to TD children. Also, children with CAS produced their vowels generally with a higher pitch and a longer duration compared to TD children. Pitch and duration were only correlated (negatively) in the vowel /a/ in both groups. Conclusions Where intrinsic pitch appears to be preserved in children with CAS, they do show differences in articulatory dimensions of vowel production compared to TD that are vowel specific. Clinicians should take these vowel specific differences into account when choosing therapeutic targets.</p>","PeriodicalId":12114,"journal":{"name":"Folia Phoniatrica et Logopaedica","volume":" ","pages":"1-18"},"PeriodicalIF":1.1,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143751793","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}

The objective of this study was to cross-culturally adapt the VFS-A-40 into Italian and validate the Italian version of the scale (VFS-A-40-Ita).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The study employed an observational design, with rigorous cross-cultural adaptation and back-translation procedures. The data were collected from a large sample of native Italian speakers aged 18 years or older without neuropsychological and/or cognitive disorders. The sample was recruited through convenience sampling and included 125 adults with hearing loss (AHL) and 203 adults with normal hearing (ANH). The validation of the VFS-A-40-Ita entailed the assessment of its construct validity (structural validity, known-groups validity, and convergent validity), internal consistency, test-retest reliability, and content validity. Additionally, face validity was assessed by a panel of 10 audiological experts, including individuals with hearing loss.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The results indicated a statistically significant difference in perceived hearing fatigue across different domains for AHL participants. Indeed, AHL tended to rate the cognitive domain as more impaired than the other domains. As for structural validity, the results of the confirmatory factor analysis provided support for a first-order one-dimensional solution comprising four correlated factors, thereby justifying the use of a total fatigue score. The known-groups validity demonstrated statistically significant differences between the AHL and ANH groups for all variables under analysis. The convergent validity was confirmed with a moderate correlation between the total scores on the VFS-A-40-Ita and scores related to the physical and mental symptoms of persistent generic fatigue (r &gt; .39; p &lt; .01). Internal consistency analysis revealed Cronbach's alpha values greater than .96 for the VFS-A-40-Ita total score, indicating high reliability. Test-retest reliability showed robust correlations between baseline and retest scores (p &lt; .01). Content validity was deemed adequate, with almost all items meeting the item-level content validity index cut-off score of .78, as rated relevant or highly relevant by at least 8 out of 10 experts.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;the findings of this study provide substantial evidence for the validity of the VFS-A-40-Ita, confirming its relevance, validity, and reliability for the assessment of listening-related fatigue in Italian-speaking adults.
