I’m with those few, it would appear, who have no problem with regional accents, (God knows, I have one myself) but would prefer clarity and precision from national tv presenters and announcers. As a Highland Scot who has gone on to live in Glasgow and several different parts of England and Wales, I have encountered and enjoyed many different regional accents. But there is a world of difference between those who speak clearly, whilst using all the vocabulary, pronunciation and intonation specific to their dialects, and those who speak lazily: slurring their words and making no allowances for the listener. Surely the whole point of speaking is communication? It’s fine to speak as you wish amongst your cronies who will always understand your utterances, but in other circumstances it’s no more than common sense and good manners to ensure you are understood by the individual(s) whom you are addressing. If there’s any snobbishness involved, it’s on the part of those who hold their audiences in contempt by refusing to make any allowances to aid comprehension.
