The purpose of this investigation was to establish the prosthetic procedure to improve occlusion of patients with reference to speech articulation.A method was designed to determine the oral motion during speech. Three phenomena were simultaneously recorded by tow high speed TV cameras on same video tapes. These were (1) the motion of facial reference points or the mandibular movements on a MKG, (2) the spectrogram of the voice analyzed by a SSD (Speech Spectrographic Display) or DSP-Sona-Graph (3) the voice of subjects. The record was play backed on a monitor of high speed video system. The flames, at which consonants were pronounced, were identified by the spectrogram of the voice.Analyzing software was newly developed to evaluate the irregularity (smoothness) of the path of movement by measurements of the moved distance, the ratio of the moved distance to the shortest distance, changes in direction of movement, moving range and area, and the velocity.1) Five reference points were marked on the face of the subjects in midsagittal plane.2) The speech samples contained /s/ and /m/ sounds along with vowels were pronounced by the normal subjects.3) The movements of the incisal point and the reference points during /s/,/m/ pronunciation were analyzed by the analyzer (Sportias 300) dividing into four terms : (1) from the beginning of articulatory motion to the onset of the consonant, (2) from the onset to the middle of the consonant, (3) from the middle to the end of the consonant, (4) after the consonant to vowel.4) The method was applied to predict acceptable occlusal vertical dimension (O.V.D) for cleft palate patients before prosthetic treatment and paticents with mandibular prognathism before surgical correction.

本研究的目的是建立一种基于语音发音的口腔运动测量方法，以改善患者的咬合关系。用两台高速电视摄像机同时记录下这三种现象。这些是（1）面部参考点的运动或MKG上的下颌运动，（2）由SSD（语音频谱显示器）或DSP-Sona-Graph分析的语音频谱图（3）受试者的语音。该记录在高速视频系统的监视器上回放。通过声音的声谱图来识别发出辅音的火焰。新开发的分析软件用于评估不规则性通过测量移动距离、移动距离与最短距离的比率、移动方向的变化、移动范围和区域，1）在受试者面部正中矢状面上标记5个参考点; 2）正常受试者发出含/s/和/m/音沿着元音的语音样本;用该分析仪分析了/s/，/m/发音时切点和参考点的移动情况（Sportias 300）分为四个术语：（1）从发音运动开始到辅音开始，（2）从辅音开始到辅音中间，（3）从辅音中间到辅音结尾，（4）将该方法应用于腭裂患者修复前和下颌骨发育不良患者矫治前的可接受咬合垂直距离（O. V. D）的预测。
