I created a tutorial on how using the voice for basslines
and you can also improve it with the basic version of Melodyne
the problem is that the voice is a bad synth, so the result is not always “cool”
not mentioning that your laryngologist will start to rub his hands if your voice is not well-trained… 
I know what I am saying because I used Dragon Naturally Speaking for years and my larynx was quite stressed
