Northern. Whether you have the world famous Inland North accent of the Great Lakes area, or the radio-friendly sound of upstate NY and western New England, your accent is what used to set the standard for American English pronunciation (not much anymore now that the Inland North sounds like it does).
If you are not from the North, you are probably one of the following:
(a) A Southerner who hates Southern accents and tries really hard to "talk right"; or
(b) A New Yorker or New Jerseyan who doesn't have the full accent
Take this quiz now - it's easy!
Then again, it could be that I'm a southerner who grew up in the metro Atlanta area, where we hear all kinds of accents. Or that I watched too much television as a child, and broadcasters use the same standard. In any case, the author of the quiz seems to be a bit out of touch as far as the explanations of different results go (and a bit defensive, as well).
