Was wondering if this happened to anyone else.

Was wondering if this happened to anyone else. Back in elementary school, my stutter was so bad that I just basically never talked unless I needed to but then in seventh grade, it started getting a lot better on its own and I began to speak a lot more. Now the problem is that now my friends and I have noticed that I seem to pronounce certain words in different accents (so far we've found British and Swedish) I live in Canada and do not have any European roots. Now the only explanation I can think of for this is that I started watching the DSMP and mostly the British creators itself during the seventh grade. I also started watching a lot of this one Swedish youtube. ​ I'm wondering if there's somehow a link between those two. Maybe it was an auditory and vocal thing since I hadn't really practiced pronunciations that much before. I heard their pronunciations, and since I was essentially learning what I was supposed the words came out of my mouth that way? ​ I wonder if there is anyone who can explain this to me because I can't find anything online about it. ​
