1 yr. Ago, I had a very soft voice because of which most of the times people think that it's a girl on a phone although I am a boy. So, I strained my voice by Hardening it, Because of which my voice is very harsh & broken now. And I keep stuttering when I sing a song specially a rap song which was not at all a issue for me at that time. So, I just wanna know how can I improve my voice quality and Speak fluently, clearly and fast.
