How should I warm up my voice?

So recently I've been super obsessed with rap covers and songs that are really fast... I want to cover them, but when I do I tend to stumble over my words very often. So I was wondering if it's because I don't warm up my voice enough?

If it is because I don't warm up my voice, then how should I do it? ( Besides the choir way which is to sing chords)

Thanks so much for the help!

I'm not sure what it is that you're doing, but what I usually do is slow it down, keep practicing until I get each of the syllables down in the correct rhythm/pitch, then slowly speed it up. Sometimes I'll write the lyrics down on a separate sheet of paper so I can view it more easily rather than trying to read it on a computer screen. This slows down the pace for everything, including how I'm taking it in mentally, until I've mastered it, so when it is the actual speed, it's a lot easier to rattle off. 

xD Hope that is of some help.

OOOOHHHHH!! THANK YOU AERLITH-SEMPAI! That really helps a lot!! >___<^

I know this is quite old, but if you're still having trouble-- besides this method (which I also use ehehe)-- you can also make sure you don't open your mouth too wide. See, when you rap/sing fast songs, the lower you let your draw drop, the longer it is for your mouth to get back to the top to make a certain pronunciation. It's impossible to not move your jaw at all, but try to make sure it's very limited--you're mainly using your tongue/very small mouth movements.

To test this, place your hand slightly below your chin, (so that your fingers are not touching your chin...but are close enough you feel it's heat/presence, I suppose--it's almost like a 1cm distance). You can say things a lot faster this way. Do two takes, one where you open your mouth normally/wide, and one where you try the limited mouth movement--and see if you can hear the difference ^^ 

for example the "Lo" in love, "air" in very, "muh" in much for "I love you very much" drops down your jaw really low at those syllables. however, it sounds like a chant when you say it with limited jaw movement. It's kind of a bad example, but it worked for me xD esp. for Dragon rising. I just stumble on one part because it's a tongue twister for me @-@ (b/c of the repeat of a certain syllable) sometimes I get it---and sometimes I don't.
