| 摘 要： | 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。

| Abstract: | Vibratory patterns of the vocal cords were studied in healthy subjects and patients with vocal lesions to observe the frequency,amplitude and the speed of vocal cord movement.Phonetic and electroglottographic parameters were also compared among different groups.Parameters from patients were significantly diffferent from the normal controls. |
