Wooow!

Your voice sounds really cute, I wouldn't have thought it was a male's voice at all, despite being low sometimes, but you're on the good track since even when your voice sounds, it's still distinguishably "low female voice". I think it does have some breathiness to it and need to enunciate a bit more clearly, I think that'll come with training. Also, you can download Reflectere, a programme in which you are able to record your voice and see its harmonics and frequency. An adult female averages 210hz, however anywhere above 160hz is good enough already, perceived as "low female voice", while a male adult voice averages 120hz, while children voices range from 250 to 400.
