This study investigated the change of eight CWS's dysfluencies according to modification of articulation rate and response latency time (RTL). The control situation consisted of a total of four subjects with normal articulation rate and normal RTL, normal articulation rate and long RTL, slow articulation rate and normal RTL, and slow articulation rate and long RTL. Also, the change of CWS's articulation rate and RTL was investigated.
The results showed that the dysfluency frequency of all CWS tended to decrease in modification with slow articulation rate and long RTL more than the other control situations. There was no significant change in CWS's articulation rate and RTL even with modification of articulation rate and RTL. Based on these results, it is suggested to use slow articulation rate and long RTL to promote fluency of CWS not according to result by change of articulation rate and RTL but by time pressure.
The results suggest that using slow articulation rate and long RTL helps promote CWS fluency in speech clinics. Therefore, this study is meaningful in that it provides the importance of observation and education of parent's articulation and RTL.
