It seems like a potential combination of "brevity" (conciseness) and "loquacious" (talkative). However, combining these words in this way doesn't create a meaningful or standard term.
If you're looking for a word to describe someone who speaks concisely, you could use:
* Concisely
* Briefly
* Succinctly
* Laconicly
