Random fact 1:
The Midwest accent is considered the most "neutral" accent. Broadcasters and actors are taught to try to copy a Midwestern accent. I live in the Midwest, but that is straight out of many years of acting (including on the west coast) and a few years of school with the goal of becoming a broadcaster (until I realized it was boring to me). However, the Midwest has various accent (I have a northern Midwest accent, I stretch my "o"s), so the area that is usually singled out is northern Kansas area (near Kansas City/ NE boarder).
Random fact 2:
The accents of NE are just as varied as the Midwest. But, areas of NE have accents that are closer to the accents of the British in 1500-1600's than the current accents within England. So, if you want to know what Shakespeare sounded like... go to NE.
I say Bay-duh. I just can't seem to pronounce it the correct way. I know how to pronounce it the correct way, it just gets stuck. It does end up sounding like better when I say it.
