介绍:
And the larynx is the site of your voice. When baby humans are born today, their larynx is not descended yet. That only happens at about three months old. So, metaphorically, each of us here has relived the evolution of our whole species. 喉头就是你发声的地方。当婴儿出生的时候，他们还没有喉头，在三个月大的时候才长出喉头。打个比方，在座的每个人都重新体验了一遍人类的进化。
And talking about babies, when you were starting to develop in your mother's womb, the first sensation that you had coming from the outside world, at only three weeks old, when you were about the size of a shrimp, were through the tactile sensation coming from the vibrations of your mother's voice. 说到婴儿，当你在母亲的子宫里开始成长，你对外界产生的第一个感知，在你只有几周大，还只有一只虾那么大的时候，是通过来自于你母亲声音震动所产生的触觉。
So, as we can see, the human voice is quite meaningful and important at the level of the species, at the level of the society -- this is how we communicate and create bonds, and at the personal and interpersonal levels -- with our voice, we share much more than words and data, we share basically who we are. 因此我们可以看到人类的声音在物种层面是很有意义也是很重要的，在社会层面也是如此——这是我们交流和建立连接的方式，在个人和人与人之间的层面——有了声音，我们分享的不仅仅是字和数据，我们展示的是自己。
