Amazing sound technology

D: Mum, how do words come out, just by opening your mouth?
Me: Well… air comes up from your lungs and goes through a voice box which changes the air into a noise. That noise goes up your throat into your mouth, and you can change the shape of your mouth to make different sounds.
D: But how do you get words?
Me: The different sounds together make up words.
D: Oh… Mum?
Me: Yes?
D: What’s a box doing stuck in your throat?
