自我维持的声带振动可能有两种机制之一或两者：（1）粘膜波沿声带内侧表面沿着传播;（2）声道提供惰性电抗。定量比较表明，粘膜波机制具有较低的阈值压力和较高的声门效率，而声门上惯性机制可以辅助振荡，是优化两种机制的有效途径。得出的结论是，最佳参数是粘膜波速度的顺序为1米/秒和直径的喉管（epilarynx管）的顺序为0.8厘米。
Self-sustained vocal fold vibration is possible with either or both of two mechanisms: (1) a mucosal wave propagating along the medial surface of the vocal folds and (2) a vocal tract that offers inertive reactance. A quantitative comparison shows the mucosal wave mechanism has a lower threshold pressure and a higher glottal efficiency, but the supraglottal inertance mechanism can assist in the oscillation and is effective in optimizing the two mechanisms. It is concluded that optimal parameters are a mucosal wave velocity on the order of 1 m/s and a diameter of the larynx canal (epilarynx tube) on the order of 0.8 cm.
