It's All In Your Head Space

Why your voice sounds different when listening to it from a recording.

Nice short piece in Popular Science about why your voice sounds different (eg. deeper and fuller) when you hear it from a recording than when you speak out loud. It's all about the vibrations, according to Ben Hornsby, a professor of audiology at Vanderbilt University. What you hear when you speak is the sound waves coming out of your mouth and hitting your eardrums--the same as what other people hear--mixed with those waves reverberating though your skin, skull, and internal oral cavities.
