本文设计了一种确定说话时下颌骨位置的方法，在16 mm电影胶片的同一帧上同时记录下颌骨运动轨迹、声谱图和嗓音三种现象。在全口义齿不同垂直尺寸的条件下，测量无牙颌受试者的/s/、/f/和/m/位置。结果表明：（1）不仅/s/位置，而且/m/位置也随口腔内条件的变化而瞬时变化。2)在一定程度上，无论咬合垂直方向的差异如何，/s/位置的咬合间距几乎不变。而在闭合状态下，垂直方向的距离变大，而在开放状态下，垂直方向的距离变小。3)/m/的位置根据它们之前和之后的元音而变化。随着垂直向的增加，/m/位的牙合间距离逐渐减小。4)/m/位置的变化比/s/位置的变化更温和。通过观察/s/、IP和/m/发音时下颌骨的运动情况，可以确定咬合垂直距离的合适范围。
A method was designed to determine the mandibular positions during speech; in which three phenomena, namely,() the path of the mandibular movements,(2) the spectrogram of the voice, and (3) the voice soundwere simultaneously recorded on the same frame of 16 mm motion picture films. The/s/,/f/and/m/positions of an edentulous subject were measured under the conditions of various vertical dimensions of the complete dentures. The results may be summarized as follows: 1) Not only the/s/position but also the/m/position are variable instantaneously according to the changes in the intraoral condition. 2) The interocclusal distances in the/s/positions were almost constant regardless of the difference in the occlusal vertical dimension to some extent. But in the case of closed occlusal vertical dimension, it became larger; it became smaller in the case of open occlusal vertical dimension. 3) The/m/positions varied according to the vowels which preceded and followed them. The interocclusal distance in the/m/position decreased gradually according to the increase of the occlusal vertical dimension. 4) The changes in the/m/position were gentler than those in the/s/position. It seems that the proper range of the occlusal vertical dimension can be determined by observing the mandibular movements during/s/, IP and/m/pronunciation.
