Is there a term for speech that gradually accelerates?
I was having a conversation with a friend about typing text crammedtogetherlikeso, to emulate a very quick speaking pattern. He mentioned cadence in regards to this, but I was thinking that cadence was more for rhythm in speech. I was wondering if there existed a specific term for a gradual or sudden acceleration or deceleration in speech to convey excitment or apathy or the like. (Primarily while talking, not so much in text; though if there were a word for that it would be good to know as well.)
