Apparently after four days in Nashville I almost sound like I'm from here.
I seem to pick up and subconsciously imitate accents very quickly.
The beer probably helps
I do that as well. I've been told it's a sign of an easily influenced mind.
It's called echolalia. I only know because I do it too.
Did you actually read that? I don't think this is what it is.
Ah, no I didn't read that. I was just remembering what I was told it was called. I didn't actually link from the wiki page, I just typed it out.
That being said I do think that's what it is. Just because it's associated with those conditions doesn't mean it only occurs in people who have them.
Conditions aside, what you're talking about isn't at all what's described. I want to say what you're describing is actually just called accent mimicry.
