The purpose of this study was to compare the performance of children with Childhood
Apraxia of Speech (CAS), children with an Articulation Disorder (AD), and children with typical
development (TD) on both speech and music tasks. More specifically, this research investigated
acoustic parameters and motor performance in 12 children ages five to ten years old across these
tasks. The specific acoustic parameters that were analyzed were fundamental frequency, average
intensity, and the specific motor performance feature analyzed was timing accuracy. No
differences among children with CAS, AD, and TD with acoustical features. However, there
were differences among children with CAS, AD, and TD with Percentage of Consonants Correct
(PCC) and Percentage of Intelligibility (PI). Additionally, there was not motor differences in
timing accuracy among the children with CAS, AD, and TD.
