Again, the cities cited as most similar to my manner of speaking are predominantly from the Northeast/Mid-Atlantic United States.
I feel this is primarily a function of the test being driven by selection of words/expressions upon visual cue, as opposed to analysis of an audio (WAV/mp3) file of my voice.
A while ago there was a thread that asked people to make a short recording of their voices and post it; I did so and will try to dig it up; I don't think I sound like I'm from the Mid-Atlantic, however I apparently use a lot of similar vocabulary as people from that region.
Finally, of greatest interest to me was the map presented with the results of my test:
The "hot spots" - or regions where language used by the locals is of greatest similarity to that of my question responses - are all locales of the U.S. that I lived in for 1 to 2 years as a child.
Places I've lived since birth to now are listed in order below; the hot spots of the map are bolded:
1974 - 1979 = Heidelberg, Germany
1979 - 1981 = Fort Hood, Texas
1981 - 1983 = Frankfurt a.M., Germany
1983 - 1984 = Carlisle, Pennsylvania
1984 - 1986 = Indianapolis, Indiana
1986 - 1988 = St. Louis, Missouri
1988 - 1994 = Reston, Virginia
1994 - 1996 = Orlando, Florida
1997 - 1998 = Fairfax, Virginia
1998 - 2012 = Tallahassee, Florida
2012 - Present = Virginia Beach, Virginia
So my hypothesis is that between the ages of 9 and 14 the dialect(s) of the regions I lived imprinted on me and have wound up influencing the word choice/terminology I use conversantly.
Apparently I use a lot of the same words/expressions as people from those regions - but I maintain that I do not sound that way IRL.
I'll find that audio file in the other post to see if I can substantiate my claim, or be told I'm full of shit, whatever the good people reading this thread and who to reply as such decide.
