I grew up in a working class area of the UK, went to a very bad comprehensive school where even the nerdy kids like me spoke chavvy english and never really spoke standard english. I was fortunately gifted in maths/science and could type/write adequate english essays; however, I never developed the ability to speak fluent english confidently which will be a major burden for me when I step into any professional situation.
Standard english feels like a closely related foreign language when compared to chavvy english which feels like my mother tongue. For example if I had to explain a concept in chavvy english, I can coherently and confidently explain that concept to a person who comprehends chavvy english, whereas if I had to explain a concept in standard english I sound very unclear and unconfident.
Any tips on how I can become a more confident and fluent english speaker, as unfortunately people can be very judgemental about your dialect.
