Yes there are many different accents in English .Even across a city local accents are still evident . Immigrants can be heard with E London accents even if wearing turbans and so on.
I don't know about speaking like this because I don't live in England although my family is English:). I have heard that the RP ( received pronunciation) seems to be becoming rare now. Even many newscasters no longer use it, when it used to be de rigueur. When it comes to the writing, I'd have to say no. Of course, I could be wrong. I'm old and have always consumed books the way some people eat chips, and I haven't run across any, but I'm not familiar with every author there is, lol. I've read modern authors with good plots and characters, but their word choice and mastery of the language is always missing. They try to overcome with grit, edginess, profanity, shock value or gratuitous sex and violence what they lack in vocabulary. I've even noticed this in other channels that narrate Victorian stories! When they write and narrate their own stories, they're filled with really graphic violence and profanity; then again, most people ( unlike us) don't seem to mind it. I came across a conversation in the comments section of a story between two millennials stating that a book was too old to bother with because it was written before the 90s, so it couldn't be any good. Can you imagine 😮? Imagine missing out on all of the books written before 1990. Although, I will say there is one youngish author who is British named Jasper L"estrange. He writes ghost and suspense stories and narrates them, and honestly, I find his stories so well crafted that I really was very surprised to find first, that they were modern and second, that he had written them, and I even told him so. His response was that because all he reads are Victorian and Edwardian stories, he seems to have absorbed the vocabulary and cadence almost by osmosis, lol. But other than this one exception, this channel is as good as narration gets. It's purely wonderful in every way, and I don't think its equal is to be found.
I enjoyed the reading- but was Welwyn EVER pronounced as it is spelt ? Surely it was always 'Wellin' ?? (Even when pronounced by upper class chaps in the 20s and 30s...)
The best part of the "Posh" accent is that it is easily understood by most people, it is more universal than obtuse accents or the dreadful Estuary English with its glotal stops and slang.
I totally agree. I am a foreigner with an MBA in English literature, and this is the real British accent for us. Whenever I visit London people are almost surprised hearing me speak the language with the normal accent which they consider posh😂😂
Sounds like the actor Edward Fox? I remember him from a "Chillers" episode called What The Cat Brought In with Bil Nighy. Introduction by Anthony Perkins.
