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.
