I’m not sure if this is going to sound strange, but I’m so accustomed to the voices of different kinds of people that my mind at this point just registers the many different accents as different voices within one accent (as in my mind doesn’t say “oh that’s another accent” anymore, it doesn’t register it) and I actually miss being able to appreciate peoples’ accents as accents, which sucks when for example you’re attracted to them.
No idea. I don’t think I have an accent but people who aren’t Canadian think I do.
Interestingly my friend’s sister moved with her twins to Australia when they were 5, and when they returned one has an Australian accent and the other does not.
