<p dir="ltr">The goal of the study was to investigate vowel accuracy in preschoolers with and without speech sound disorders (SSD) on nonword repetition tasks. Children ages 4 and 5 years completed a battery of speech and language measures, as well as two nonword repetition tasks, the Syllable Repetition Task (SRT) and the Nonword Repetition Task (NRT). A total of 41 children participated in the study divided among 3 groups: 14 children with typical speech and language skills (TD), 14 children with isolated speech sound disorders (SSD-only), and 13 children with SSD and comorbid Developmental Language Disorder (SSD+DLD). Ultimately, it appears that children with SSD+DLD make more vowel errors on the Nonword Repetition Task, and that vowel accuracy on nonword repetition tasks and phonological awareness may share underlying mechanisms.</p>
