How Can You Hear Your Voice on Phone Calls?

Your brain hears your own voice differently when you talk on the phone. When you speak normally, the sound of your voice travels through the air and into your ears, but it also goes through your bones in your head, which makes it feel deeper and richer. On a phone call, that extra path is missing, so it feels like your voice is smaller or higher-pitched when you hear it on the other end.
