AI Article Synopsis
- - The study analyzed vowel use and error patterns in three children suspected of having developmental apraxia of speech (DAS) over three years using recorded speech samples.
- - All three children had nearly complete English vowel inventories, but their accuracy in using vowels didn't improve and showed no clear patterns of error.
- - The results suggest that even with a full set of vowels, the children struggled with vowel accuracy, highlighting the need for better diagnostic tools for identifying DAS.
Article Abstract
Vowel inventories and error patterns for three children with suspected developmental apraxia of speech (DAS) were analysed over a 3-year period using phonetic transcriptions of connected speech samples. The children demonstrated complete English vowel inventories except for rhotics. However, accuracy of vowel targets in connected speech did not normalize during this period. No consistent patterns of vowel errors were found. There was no decrease in vowel accuracy with increased utterance length or syllable complexity. Findings indicate persistence of vowel inaccuracy in the presence of a relatively complete vowel inventory. This longitudinal data can help to build consensus on use of vowels as a potential clinical marker for differential diagnosis of DAS.
