It's due to the testosterone that is being produced to help develop secondary sexual characteristics as a boy matures into adult hood, which includes a deeper voice, growth of pubic and armpit hairs (sometimes chest, depending on genetics), and maturity of the genitals and reproductive glands.

Yes, just like boys, but not as low.
It's the larynx (or voice box) that's causing all that noise. As the body goes through puberty, the larynx grows larger and thicker. It happens in both boys and girls, but the change is more evident in boys. Girls' voices only deepen by a couple of tones and the change is barely noticeable. Boys' voices, however, start to get significantly deeper.
some change but for http://wiki.answers.com/Q/FAQ/6602it still dosent change
when they grow up there voices change naturally. soooo no they did not take testosterone.. they grew into HOT boys and their voices changed
Some men have higher voices than others and that is natural. The change in a boys voice occurs towards the end of his puberty, but if a boy has truly completed puberty then his voice is likely as low as it is going to get.
Girls' voices become a bit more high-pitched, whereas boys' voices turned deeper. Well, that's what I learned at school and I hope it's true!!
Because their voice boxes have not grown or stretched until Puberty begins. As they go through puberty boys voices change and get deeper due to the aforementioned.
There is not an exact age for what age boys voices deepen, because we all go through puberty at a different time. Approximately, boys voices deepen around eleven through around fourteen. That still doesn't mean their voice is changed and is not going to still change, because it could still get deeper. Also, a boy's voice can change sooner or even later. I know this because there are a lot of boys in my grade (Sixth grade) I've noticed that their voice deepened.
