I have noticed in the last 20 years (I am nearly 53) regional accents become a lot more acceptable. I got ridiculed for my (not that strong but distinctive) Scottish accent in London in the eighties and also at uni in Edinburgh. I hadn’t met the very rich before that and it was a shock. I was into drama but after feeling isolated among the RP speakers I didn’t return to a group and stopped acting altogether. They seemed to think that anyone with any kind of regional accent was extremely poor and lower working class. There was a clear class divide at the university.
As a student at school I was mocked by the more strong accented kids (in Fife) and told I had been sent to elocution lessons by my mum which was incorrect. There seemed to be a thing about talking as broad as possible to avoid being called a snob (inverted snobbery). I have been told several times I sound like Kirsty Wark and am happy with this. I now live in West Yorkshire and have adopted some of that dialect but never lost my Scottish accent.
I grew up in the South East, in and around Royal Tunbridge Wells. I went to university up north and uni friends, housemates and course-mates (vast majority Northerners) would often remark on the way I pronounced things, particularly the classics like ‘grass’ and ‘bath’. One person would repeat the word/phrase in an over-done RP accent and the rest of the group (including me, most of the time) would get a bit of a giggle out of it. People would often assume I had loads of money and my family were landed gentry or Viscounts or something.
I went to the ‘second’ university in the town (an ex-polytechnic) and, interestingly, people I met who didn’t know that, would assume that I went to the ‘primary’ university in the town, renowned for being (better) and with higher entry requirements.
Definitely found myself inadvertently adopting a bit of a Northern twang by the time I got to third year!
I remember being so happy I’d made a friend on my first day at uni. Later that day I heard her mocking the way I said ‘cake’ (in my Yorkshire accent) to another student.
