Interesting NASA website where you can even test how your voice would sound on Mars. To me, the effect was my voice sounded more muffled and slightly lower in pitch.

Wow, liberals might finally start sounding like men! Maybe they'd start acting like it too. Send all liberals to Mars!
Love the site. Great find.
Maybe just using chocolate will lower your tone of your voice?

I would think that sounds shift to higher pitch — like inhaling helium and speaking — lower density
