Why does your recorded voice sound like a stranger?

When you speak, two sounds reach your ear at once: one travels through the air…

the other vibrates through the bones of your skull

Those bones add bass frequencies that no one else can hear

A microphone only captures the airborne voice: the bass drops away

This mismatch even has a name: voice confrontation

Everyone already hears you that way

Except you

Your voice isn't the strange one — it's the one you thought you had
