项目摘要

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.

本研究的目的是收集数据，研究脑瘫儿童在自主运动中出现的自主和非自主运动量。进行了两种研究。第一个研究是利用三维位置检测器对上肢运动的研究。第二个研究是关于脑瘫儿童的运动障碍声音的研究。利用位置检测器通过磁场测量上肢位置，制作了一种全木椅来测量上肢的位置。收集了两名脑瘫儿童的简单地理模式追踪数据。数据显示了左右肢体之间的差异，以及不同试验之间的差异。异常声的声学参数变化比正常说话者的变化宽几倍。独立于说话人的语音识别器VFF-100P的正确识别率优于耳朵的可理解性。如果我们可以为交流准备一个或多个缓冲阶段和一个合理的识别器，不稳定的困难声音将变成有用的准稳定的声音。
