Abstract

The nature of vowel acquisition and vowel error patterns in young children, especially those with speech sound disorders (SSD), is not well understood. Previous studies of vowels produced by children with SSD of unknown origin (SSD-TJNK) have shown that they demonstrate a similar order of acquisition and vowel error patterns as those of children with TDS (typically developing speech), but are slower in developing vowels and produce more vowel errors. Adult participants were 15 women, ages 18 to 35 years. All were monolingual speakers of Western Canadian English with no history of speech delay or disorder. Two groups of children participated (TDS and SSD-UNK), with three children in each of four age groups in each group for a total of 24 children. Vowels of all groups were more successfully classified with two measurements representing the formant movement patterns, than a single point measurement, and a combination of all acoustic measures than a single or a subset of measures.
