If it was back in India, it wouldn’t matter as everyone spoke in normal english except some people, the so called “NRI’s” or who want to show off their english “accent” . But some people have a natural stylish accent and thats by practice(maybe influenced by movies, tv shows ..etc..) . By the way its very easy to distinguish between a natural and fake “english style” of speaking.
We Indians speak good and clear english.. too general .. esp me , i talk clear and fairly good english, but my english isn’t
stylish. I never tried to make it stylish, I just make sure that my talk is clear to the listener.
