The author reported that the purpose of this study was to evaluate the speaking rate and articulation rate of CWS and children who do not stutter (CWNS) and their respective parents. The results indicated that CWS had a slower speaking rate and articulation rate than CWNS. The PCWS group had a slower speaking rate than parents of children who do not stutter (PCWNS) but yielded similar articulation rates. These findings suggest that CWS and PCWS do not necessarily speak faster than those who do not stutter. Rather, a reduced speaking rate may actually serve to facilitate moments of fluent speech production.
