应用486微型计算机和北京邮电大学通用信号谱分析系统分别对30例青年女性喉病患者和36例健康对照组的/a/、/i/音嗓音信号进行频谱分析,比较其相对信噪比,结论是在频谱分析中用/a/音采样较/i/音更易检出病态嗓音.
The spectrum analysis of the / a /, / i / voice voice signals of 30 young women with laryngeal disease and 36 healthy controls was carried out by using the 486 microcomputer and the general signal spectrum analysis system of Beijing University of Posts and Telecommunications respectively. The relative signal- The conclusion is that it is easier to detect morbid voices with / a / s than with / i / s in spectrum analysis.
