ELI5: Why do auctioneers call out the way they do?

Is there a reason or just tradition?

The intent is to talk fast to move things along more quickly. However, what you're hearing is an intentional type of pronunciation from which you can decipher what they are saying, partly because of how they enunciate, but also because it's consistent and you learn how to listen to them pretty quickly at any auction. Also, they repeat numbers and situations constantly, which serves the purpose if clearing confusion for people who might mishear once. Lastly, the repetitive and fast nature, with no dead space, keeps things feeling more anxious, for lack of a better term, and more likely to make buyers make snap decisions, especially in a novice buyer. 

So in part, it is tradition, but moreso for the purpose it serves than just to keep a tradition alive.
