减少听觉信息的言语产生的空间和时间参数的影响进行了研究，使用电影荧光技术。当受试者阅读一系列嵌入在载体句子中的测试词时，他们接收到（a）正常听觉信息，（B）仅关于其产生的第一格式的听觉信息，或（c）高电平噪声以掩盖所有共振峰信息。运动学分析表明，虽然有一些变化的条件下，这些变化是不一致的，无论是内部或跨学科。受影响的参数包括位移，声道形状，interarticulator定时，和稳态持续时间。结果表明，听觉信息在维持语音运动学的动态方面起着重要作用。也就是说，虽然言语可以在没有听觉信息的情况下产生，但表征正常产生的精确动作和协调可能会改变。
The effects of reduced auditory information on spatial and temporal parameters of speech production were investigated using cinefluorographic techniques. While subjects read a series of test words embedded in carrier sentences, they received (a) normal auditory information, (b) auditory information regarding only the first format of their production, or (c) high level noise to mask all formant information. Kinematic analyses indicated that while there were some changes across conditions, these changes were not consistent either within or across the subjects. Parameters that were affected included displacement, vocal tract shape, interarticulator timing, and steady state duration. The results suggest that auditory informations plays a role in maintaining dynamic aspects of speech kinematics. That is, while speech can be produced without auditory information, the precise action and coordination that characterize normal production may be altered.
