Preliminary Study of Voluntary and Non voluntary Movements of Cerebral Palsy Children.

本研究的目的是收集资料，研究脑瘫儿童在自主活动中出现的自主运动量和非自主运动量。第一个研究是使用三维位置检测器研究上肢运动。第二项研究是脑性瘫痪儿童的构音障碍研究。为了测量上肢的位置，制作了一种全木质椅子，因为位置检测器是通过磁场来测量位置的。收集了两名脑瘫儿童的简单地理模式追踪数据。数据显示了右手和左手肢体的差异，也显示了逐一试用的差异。发音障碍的声学参数变化比正常说话人的变化幅度大几倍。不依赖说话人的语音识别器VFF-100P的正确识别率要好于人耳可理解度。如果我们能够准备一个或多个用于交流的缓冲级和一个合理的识别器，不稳定的构音障碍将成为有用的和准稳定的声音。

The purpose of this study is collecting the data to study the amount of voluntary and non voluntary movement which is appeared in voluntary movement of cerebral palsy children.Two kinds of studies have been carried out. The first study is the study of upper limb movements with three dimensional position detector. And the second study is the study of dysarthric sound of cerebral palsy children. An all wooden chair was produced to measure the position of upper limb, because of position detector which measures position by mean of magnetic field. Data for tracing on simple geographic patterns have been collected for two cerebral palsy children. Data shows the differences between right and left limb, and also trial by trial differences. The variation of acoustic parameters of dysarthric sound is several times wider than the variation of normal speaker. The correct recognition rate by a speaker independent speech recognizer, VFF-100P, is better than the intelligibility by the ear. If we can prepare one or more buffer stages for communication and a reasonable recognizer, unstable dysarthric sound will become useful and quasi stable sound.
