PURPOSE
The purpose of this longitudinal study was to examine the effect of time and sentence length on speech rate and its characteristics, articulation rate and pauses, within 2 groups of children with cerebral palsy (CP).
METHOD
Thirty-four children with CP, 18 with no speech motor involvement and 16 with speech motor involvement, produced sentences of varying lengths at 3 time points that were 1 year apart (mean age = 56 months at first time point). Dependent measures included speech rate, articulation rate, proportion of time spent pausing, and average number and duration of pauses.
RESULTS
There were no significant effects of time. For children with no speech motor involvement, speech rate increased with longer sentences due to increased articulation rate. For children with speech motor involvement, speech rate did not change with sentence length due to significant increases in the proportion of time spent pausing and average number of pauses in longer sentences.
CONCLUSIONS
There were no significant age-related differences in speech rate in children with CP regardless of group membership. Sentence length differentially impacted speech rate and its characteristics in both groups of children with CP. This may be due to cognitive-linguistic and/or speech motor control factors.
目的
这项纵向研究的目的是在两组脑瘫（CP）儿童中，研究时间和句子长度对语速及其特征、发音率和停顿的影响。
方法
34名脑瘫儿童，其中18名无言语运动障碍，16名有言语运动障碍，在相隔1年的3个时间点说出不同长度的句子（第一个时间点的平均年龄为56个月）。相关测量指标包括语速、发音率、停顿时间比例、停顿的平均次数和时长。
结果
时间没有显著影响。对于无言语运动障碍的儿童，由于发音率提高，语速随着句子变长而增加。对于有言语运动障碍的儿童，由于较长句子中停顿时间比例和停顿平均次数显著增加，语速不随句子长度变化。
结论
无论所属组别如何，脑瘫儿童的语速均无显著的年龄相关差异。句子长度对两组脑瘫儿童的语速及其特征有不同影响。这可能是由于认知语言和/或言语运动控制因素。
