目的用多言语子系统方法检测脑瘫儿童的言语声学特征，用预测模型评价言语清晰度，在该模型中，选择声学指标来代表3个言语子系统。这些儿童包括13名临床诊断为构音障碍的儿童（言语运动障碍[SMI]组）和9名判断为无构音障碍的儿童（无SMI [NSMI]组）。从CP儿童的数据进行了比较，从年龄匹配的典型的发展children.ResultsMultiple声学变量反映发音子系统是不同的SMI组相比，NSMI和典型的发展组。一个显着的语音清晰度预测模型，获得了所有变量输入到模型（adjustedR2= .801）。发音子系统表现出最实质性的独立贡献（58%）的语音清晰度。IncrementalR2分析显示，任何单一变量解释不到9%的语音清晰度variability.ConclusionsChildren在SMI组发音子系统的问题，索引声学措施。在成人文献中，发音子系统作出的主要贡献，在构音障碍的语音清晰度变化，与其他系统的贡献很小或没有。
PurposeSpeech acoustic characteristics of children with cerebral palsy (CP) were examined with a multiple speech subsystems approach; speech intelligibility was evaluated using a prediction model in which acoustic measures were selected to represent three speech subsystems.MethodNine acoustic variables reflecting different subsystems, and speech intelligibility, were measured in 22 children with CP. These children included 13 with a clinical diagnosis of dysarthria (speech motor impairment [SMI] group) and 9 judged to be free of dysarthria (no SMI [NSMI] group). Data from children with CP were compared to data from age-matched typically developing children.ResultsMultiple acoustic variables reflecting the articulatory subsystem were different in the SMI group, compared to the NSMI and typically developing groups. A significant speech intelligibility prediction model was obtained with all variables entered into the model (adjustedR2= .801). The articulatory subsystem showed the most substantial independent contribution (58%) to speech intelligibility. IncrementalR2analyses revealed that any single variable explained less than 9% of speech intelligibility variability.ConclusionsChildren in the SMI group had articulatory subsystem problems as indexed by acoustic measures. As in the adult literature, the articulatory subsystem makes the primary contribution to speech intelligibility variance in dysarthria, with minimal or no contribution from other systems.
