Is it normal to develop an accent foreign to the country you live in?

I knew a Canadian once who had a French accent. Even worse, they actually spoke French. Damn craziest thing I've ever heard of since that Brazilian guy who can speak Portuguese.

On second thought, you might have Foreign Accent Syndrome.

This happened to a friend of mine. I speak with a New England accent but I live in Arizona now. My friend and I were around each other a lot, and she eventually would say things in my accent sometimes.

I'm Canadian and I do the same thing, especially when I'm excited about something or nervous.

It's not uncommon, especially among people with different neurological wiring such as those on the autistic spectrum. I have a friend on the autistic spectrum who is Canadian but speaks with a Cockney accent.

Is there any source that can be modifying your accent or is it just out of the blue? I don't think it's very normal haha, but there's nothing bad about it either.

I think it's normal if you are learning a new foreign language... Like me for example, i'm brazilian and my mother language is portuguese, but i also speak english, spanish and i'm currently learning french, and i have a different region accent for each of those languages, even though i've never been out of Brazil or spent enough time with a foreigner that speaks one of those languages that i could get the accent from. Like, when i speak english my accent sounds very australian, when i speak spanish my accent sounds argentinian, and when i speak french i sound like a looner who can't pronounce the french words lol
But it's really unusual for you being Canadian and start out of nowhere to sound scottish xD Have you been watching any tv show with scottish people on it? This also influences on your speech(this is the reason why i have random accents on each of those languages that i explained above)

I do it when I am excited or nervous too.

For people who think Canadians with a French accent is wronge it's not. Lots of Canadians do.

I live in america and sometimes I'll talk in a British accent for periods at a time.

If your new accent is:

British: You're pretentious
French: You're probably gay
African-American: You're a wannabe gangsta
Afrikaans: You listen to Die Antwoord far too much.
Irish: You're an alcoholic
Redneck: You're too religious
German: You're becoming a mad scientist
Unidentifiable: See a shrink
