I've noticed that whenever I hear my own voice being recorded and played back to me, it sounds different from when I'm just hearing myself talk. I think my voice is rather unique. I can't really explain why, it just has this sound that seems to stand out from everyone else. Also, I learned at some museum that everybody's voice in the whole world is different, like fingerprints. Wait, let me rephrase that. We each have our own voice, and nobody else's voice is just like ours in the whole wide world. Kind of mind boggling, huh? I thought that was quite interesting.
