How do i make my voice bettter?

u could have a trained voice anybody can get a trained voice its just that its plain it might soung good but anybody that has a trained voice they all sound the same........practice on higher notes and do the scales everyday my voice is deep too but im tryna get it back up in altos and sopranos and hey maybe if u wanna become a star ur accent might do the trick hey look at amywhinehouse and rihhana
