why do some cats meow sound like this?

[gypsy04]

Some cats meow sound cracked and low when they meow vs other cats that are normal high pitched and very clear why are some cats voice like this?

I have six cats and they all sound different!  One has a tiny squeaky meow that's adorable; my old boy who's 18-1/2 sounds like he has marbles in his mouth when he meows.  

   Barring any medical cause, I think they're just all different.
