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 normal auditory information, auditory information regarding only the first formant of their production, or 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 mean displacement, vocal tract shape, interarticulator timing, and steady state duration. The results suggest that auditory information 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 characteristic normal production may be altered.
利用电影荧光造影技术研究了听觉信息减少对言语产生的空间和时间参数的影响。当受试者阅读嵌入在载体句子中的一系列测试单词时，他们分别接受正常听觉信息、仅关于其发音的第一共振峰的听觉信息或用于掩盖所有共振峰信息的高强度噪声。运动学分析表明，虽然不同条件下存在一些变化，但这些变化在受试者内部或受试者之间并不一致。受影响的参数包括平均位移、声道形状、发音器官间的时间安排和稳定状态持续时间。结果表明，听觉信息在维持言语运动学的动态方面发挥作用。也就是说，虽然没有听觉信息也可以产生言语，但正常言语产生所特有的精确动作和协调可能会改变。
