How we hear our own voices doesn't match what other people
          hear.
          
          We hear our own voices through the structures of our
          heads.  This acts like a filter, getting rid of higher
          frequencies and making our voices seem much deeper.  This
          is why we have trouble recognizing ourselves on a recording.
          
          I'm a prime example of that.  To me, my voice sounds like
          George C. Scott.  To everyone else, I sound like PeeWee
          Herman.
          
          (Trivia point:  Scott is most famous for portraying
          General George Patton.  Yet Patton himself had a rather
          high-pitched voice...)
          
          In addition, my voice is apparently a bit distinctive. The
          PeeWee analogy is much more strong than I would care for.
          
          Evidence:  I stopped by the airport today to schedule my
          BFR.  The FBO is fairly new to the airport, so haven't
          worked with them before.
          
          Went in, and there were four young folks sitting in the
          office.  I mentioned I needed a BFR, and they asked if I
          was current.  "Yeah, I fly the Fly Baby...."
          
          "OH YEAH" they all chorused.  "We recognize your
          voice!  'Fly Baby downwind for 34 at Auburn!'"
          
          So I guess my reputation precedes me....
