When it comes to expressing excitement or enthusiasm, there are several ways to say "babble enthusiastically." One could exclaim with passion, gush effusively, chatter excitedly, blurt out with joy, or rave with enthusiasm. Alternatively, one might spout exuberantly, shout with glee, shriek with delight, or burst out with excitement. When words simply cannot contain the boundless energy and fervor of an enthusiastic speech, one may resort to babbling with unbridled eagerness or rambling with uncontainable zeal. Whatever the synonym chosen, the listener will surely be swept up in the contagious fervor of the speaker's enthusiasm.
