Body Trivia : How do the voices come out?

How do the voices come out?

We speak by shaking the membrane called the vocal cords in the depths of the throat by breath. 

It is same principle as our putting paper on the mouth and sounding it by breath. 

Vocal cords are hidden usually and there is a mechanism that vocal cords come out on a way of the breath in a throat to utter voice. 

Therefore, a voice does not come out when we usually breathe with a mouth. 

A mouth and a tongue play an important role to make a voice words.　　

We make words by changing the tremor of the vocal cords with moving a tongue and a mouth in various ways.
