Short spoken is often used to describe someone who doesn't say much or is not very talkative. However, there are several antonyms for this word which can be used to describe people who are quite the opposite. Some antonyms for short spoken are loquacious, garrulous, voluble, and verbose. Loquacious means tending to talk a lot, while garrulous refers to someone who is excessively talkative. Voluble means someone who speaks fluently and easily, and verbose means using more words than necessary. So, if you want to describe someone who is extremely talkative, you can use these antonyms instead of short spoken.
