为更直观有效地了解正常男女性声带疾病患者在发声和声带振动的频率、幅度及声门开放、闭合过程的速度变化，我们采用嗓音测试仪观察正常男、女性声带振动的模式和声带疾病组的变异情况。将语言信号和电声门图信号的各个参数进行比较（ｔ检验）分析得出，健康男、女性波形规则均匀，女性频率快、幅度小，男性较女性的声门开放、闭合速度为快；疾病组中波形变化较大，频率或幅度都有不同的变化；嘶哑程度也不同地影响了声带运动中的开放和闭合过程。
In order to understand the frequency and amplitude of vocal cord and vocal cord vibration in normal men and women with vocal cord disease more intuitively and effectively, the speed of vocal cord opening and closing during the process of vocal cord vocal cord vibration was observed. Variation of the situation. The comparison of the various parameters of the speech signal and electroacoustic gating signal (t-test) showed that the wave rules of healthy men and women were uniform, the frequency and amplitude of females were fast, and the glottis of males was more open and closed faster than those of females. In the disease group, the waveform changes greatly, and the frequency or the amplitude has different changes. The degree of hoarseness also affects the opening and closing process of the vocal cords differently.
