N1 - Funding Information:
This project was conducted as part of the first author’s dissertation research. It was financed by an NIH traineeship grant (NIH 05 T32 DC0003-10) and the Department of Speech and Hearing Sciences at the University of Washington. We are grateful to the University of Washington Child Participant Pool – Communication Studies and to speech-language pathologists in the Seattle, Tacoma, and Portland area for help with participant referrals. We appreciate the help with acoustic measurements and reliability assessment on the part of several undergraduate and graduate students in our department. Special thanks to the participating children and their families for their time and effort. Portions of this study have been presented at Rhythm, Time and Temporal Organisation, 2–4 June, 2006, Institute for Music in Human and Social Development, University of Edinburgh, and the 4th Joint Meeting of the Acoustical Society of America and the Acoustical Society of Japan, Honolulu, 28 November–2 December 2006.

N2 - Childhood apraxia of speech (CAS) is a proposed speech disorder subtype that interferes with motor planning and/or programming, affecting prosody in many cases. Pilot data (Peter & Stoel-Gammon, 2005) were consistent with the notion that deficits in timing accuracy in speech and music-related tasks may be associated with CAS. This study replicated and expanded earlier findings. Eleven children with speech disorders and age-and gender-matched controls participated in non-word imitation, clapped rhythm imitation, and paced repetitive tapping tasks. Results suggest a central timing deficit, expressed in both the oral and the limb modality, and observable in two different types of timing measures, overall rhythmic structures and small-scale durations. Associations among timing measures were strongest in the participants with speech disorders, who also showed lower timing accuracy than the controls in all measures. The number of observed CAS characteristics was associated with timing deficits.
