Why do our voices sound different in a recording?

When you talk on a phone or computer, your voice sounds different because it goes through a magic tunnel before reaching the other person.

Imagine you're talking to a friend across the room. You can hear them clearly because the sound travels directly through the air to your ears. But when you use a phone or computer, your voice has to go through a special kind of tunnel that changes how it sounds, like when you speak into a megaphone instead of just talking normally.

Your voice is like a balloon full of air, it makes different noises depending on how much air comes out. When you talk directly to someone, all those little noises travel through the air and reach their ears as they are. But when you use a phone or computer, your voice goes through a tunnel that only lets certain parts of your voice come out clearly, like how a sieve lets some bits of sand pass through but holds onto others.

That’s why your voice sounds different in a recording, it’s like hearing yourself talk through a funny tunnel instead of speaking directly to someone.
