在放生叫声过程中，直接观察到林蛙的喉部运动。在放飞叫声和交配叫声中，记录了尖吻林蛙和杂色林蛙喉内肌的肌电活动。喉咙的叫声运动由一个发声阶段和一个呼吸阶段组成。在呼叫过程中，声门的打开是由中枢神经对喉部固有肌肉的控制来主动调节的，而不是由来自肺部的气压被动地调节的。一种产生颤音的方法是，由于扩张肌的收缩而打开声门，同时收缩肌周期性地收缩，导致声门关闭，从而使叫声变成颤音。
Laryngeal movements were observed directly in Rana ipipens during release calling. Electromyograms from the intrinsic muscles of the larynx were recorded in Rana pipiens during release calling and Hyla cinerea and Hyla versicolor during mating calling. Laryngeal call movements consist of a vocal phase followed by a respiratory phase. Glottal opening during calling is regulated actively by central nervous control of the intrinsic laryngeal muscles and not passively by air pressure from the lungs. One method of trill production involves glottal opening due to contraction of the dilator muscles with simultaneous, periodic contraction of the constrictor muscles, causing glottal closures that break the call into trills.
