How old were you, when your voice started to change? :)?

My voice hasn't changed yet, so I'm wondering about you guys. I'm a girl. :)

Girls voices don't change. When boys go through puberty, testosterone causes the vocal cords to lengthen, thus deepening their voice. this doesn't happen to women.

Girls don't normally have that change. You will sound older when you are an adult, but it's a much lighter, gradual thing for girls.
