We have lower tones because our voice box's are larger, the sound isn't pushed out as quickly enough so it comes out lower. Whereas women having a smaller voice box can push the sound out quicker and higher, which may explain why they can say over two hundred words in less than a minute.
Thats basically it, I probably haven't explained it right, I'm sure Isherwood will be along soon to correct me .
