“
The cords, which are attached to the cartilages, are to the human speech organs what the two vibrating reeds are to a clarinet or the strings to a violin. They are capable of at least three distinct types of movement, each of which is of the greatest importance for speech. They may be drawn towards or away from each other, they may vibrate like reeds or strings, and they may become lax or tense in the direction of their length 去书内

    声带附着在软骨上，它们之于人的言语器官，就如两片振簧之于竖琴，或者琴弦之于小提琴。声带能做至少三种不同类型的动作，每一种对言语都至关重要。具体地说，两条声带可以互相靠近或远离，可以像振簧或琴弦一样颤动，还可以沿着其长度方向变得松弛或紧张。最后这种动作可以让声带以不同的“长度”或紧张度颤动，由此产生了音高的变化。这不仅出现在歌唱中，而且也出现在普通言语里更难捕捉的抑扬微调中。另外两种声门运动决定了声响的性质，这里“声响”是一个方便的说法，指的是言语中使用的气流。
