Would someone who's Scottish know what a Scottish accent sounds like?
To them, a proper Scottish accent wouldn't sound like an accent.
I can hear when non-American actors are butchering an American accent, like that guy from Avatar. So I'm sure others can do the same for their own native accents as well.
I suppose what I'm wondering is, does a Scottish person perceive a different Scottish accent the same way I would?
Probably impossible to really know.
