Something I realized is that I don't stutter when I lose my temper and yell.

Something I realized is that I don't stutter when I lose my temper and yell. Sometimes I lose my temper and yell or when I'm in an argument and raise my voice the stutter is gone. But unfortunately I can't talk like that the whole time, cause it'll constantly be a conflicting tone. Anyone else realized that or whom it happens with?
