喉功能和病理生理学的客观测定,是喉研究的目的之一。作者设计了一种新的发音系统计算工具,用于喉动态电视镜的定量分析。发音功能的客观分析包括图象、气体动力学和声学测量。动态电视镜所获得的图象,能克服声运动和高快速运动时图象照相的困难,能精确和快速得到图象的定量分析。作者设计的系统包括计算的数字化、声门图照相、声门图测量和声学信号的输入,还用于记录声带的振动。新系统通过一望远镜使声带形象地显示在电视监控器中,望远镜连接到双目电视照相机,50
Objective assessment of laryngeal function and pathophysiology is one of the aims of laryngeal research. The author designed a new pronunciation system calculation tool for the quantitative analysis of throat dynamic television. Objective analysis of pronunciation function includes image, gas dynamics and acoustic measurement. Dynamic television images obtained by the mirror, to overcome the sound movement and high-speed movement of the image photography difficult, accurate and fast images can be quantitative analysis. The author’s system includes computational digitization, glottic photography, glottic measurement and acoustic signal input, and is also used to record vibration of the vocal cords. The new system displays the vocal cords in a television monitor via a telescope connected to a binocular television camera, 50
