Is Guitar Hero helpful for voices?

Man, does this come up a lot. Thinking that maybe, just maybe, this vocal part of the game would help with the scale (Do-Re-Mi.. etc...) because of the jumps in some songs. How would I ever know that?
Well, easy! As you know, rock band, guitar hero, whatever games has vocals that you can sing a long with may help with learning the words, and maybe how to train your voice to hold notes out longer.
Pitch is not something you could learn, nor could you learn other ways to perform, but it does help you to have a good time!
