The voice on a recording is the voice everyone else hears. It sounds strange to you because you hear yourself in a special way.
How do you hear yourself?
When you talk, your voice reaches your ears through the air, but it also travels through the bones of your head straight to your inner ear. Bones carry low sounds better, so you hear a deeper voice.
What does a microphone hear?
A microphone only catches the sound in the air, so the deep part is missing, and your voice sounds higher and thinner.
Can you hear the difference?
Try this. Plug your ears and talk. Your voice gets louder and deeper because the bone sound gets trapped inside your ears.
