这项探索性治疗研究使用语音转录和语音运动学来检查节段和发音变异性的变化。研究对象为9名4 ~ 8岁的儿童，其中2名患有儿童言语失用症（CAS）， 5名患有语音障碍（SSD）， 2名发育正常。孩子们在一个模仿任务（低语言负荷）和一个检索任务（高语言负荷）中练习了五个阶段的“代理+动作”短语。在第一阶段的模仿任务中，两名患有CAS的参与者都表现出高度的片段和发音变异性。五次练习后，模仿练习导致五名参与者的发音变异性增加。检索练习导致三名SSD参与者的关节变异性降低。这些结果表明，在死记硬背模仿中进行短期的语音生成练习会破坏有或没有CAS的儿童的发音控制。相比之下，需要语言处理的任务可能会促进SSD儿童的学习，而不是CAS儿童。
This exploratory treatment study used phonetic transcription and speech kinematics to examine changes in segmental and articulatory variability. Nine children, ages 4 to 8 years old, served as participants, including two with childhood apraxia of speech (CAS), five with speech sound disorder (SSD) and two who were typically developing. Children practised producing agent + action phrases in an imitation task (low linguistic load) and a retrieval task (high linguistic load) over five sessions. In the imitation task in session one, both participants with CAS showed high degrees of segmental and articulatory variability. After five sessions, imitation practice resulted in increased articulatory variability for five participants. Retrieval practice resulted in decreased articulatory variability in three participants with SSD. These results suggest that short-term speech production practice in rote imitation disrupts articulatory control in children with and without CAS. In contrast, tasks that require linguistic processing may scaffold learning for children with SSD but not CAS.
