Learn English – When someone says something in a foolish, excited, or incomprehensible way for a brief moment

Is there a word that describes when someone blurts out something quickly and excitedly and in a sort of foolish way? For example, the word babble describes the act of "talking rapidly and continuously in a foolish, excited, or incomprehensible way." The word I'm looking for is similar, but doing it hastily and only for a short bit.

For example, the context I'm using it in is a soldier saying a quick, incomprehensible prayer before the eve of battle that no one around him really catches the meaning of. I could say that he "babbles a prayer," but if he only does it for a short moment, it doesn't really fit the context.
