The accent was neither entirely Southern nor was it entirely ethnic in origin. It sounded like slurred speech that I've heard in bars late at night around last call but this was at 8am on a Monday. Attempting to put characters to the accented speech I heard would be like attempting to transcribe a previously untranscribed language. I think I would have to invent new characters for the pronunciations even to being to approach the speech pattern.
I am glad to know that it is not just in Second Life that new dialects of the English language are being developed. I've heard dialects in spoken speech here in the Atlanta area that begin to stretch the mind and cause me to start to think about the origin of the speech patterns that formed the speaker's way of speaking. In Second Life, I've "heard" written speech patterns that, while entirely readable, cause the mind to have to shift slightly to understand what is being said. When the reality in which you are communicating encourages you to type faster than your mind sometimes can process, spelling is often thrown to the wind and articles of speech as simple as "the" get misspelled. I've often called this dialect of unspoken speech SLese for lack of a better name. The dialect I heard this morning has no name unless Southern-Creole-Slurred-Sports-Talk has a name.
