Again you say, "Of course."But that's not quite true. Nobody else has ever heard your voice--the way you hear it. When you talk, you set up sound waves . The air outside your head carries the sound waves to your outer ears. But, of course, the sound of your voice begins inside your head. The bones of your head pick up the sound waves, too.

That's why they don't hear your voice the way you do.
