Change my American English to RP English?

[tungemål]

What about learning the Mid-Atlantic accent?

I am a bit fascinated by this learned accent that only lasted a couple of decades. Apparently actors in old movies used it (before 1950). I think it was basically an American version of a posh British accent.

I started learning English with a (Midwest) American accent since I was in early grade school in the US. I've always been fascinated with the "Posh" accent/RP English, and I want to know how to go about doing this. Can someone suggest useful resources? Also how long must I study it until I see significant results if I dedicate 1-2 hours a day, everyday on this?

Someone mentioned "BBC 4". I don't know if they were talking about the TV channel or the radio station.
(The TV channel is usually written as BBC four). However, BBC TV via the internet is not officially available outside the UK, i.e. it is geo-restricted.

I am reasonably sure that BBC Radio via the internet is still available unrestricted anywhere in the world, although you may have to register. There used to be something called "iPlayer Radio", but nowadays it's called "BBC Sounds". There is a website:

And there is also a mobile device app:

What stations to listen to? Well, Radio 4 definitely (i.e. BBC Radio 4). As someone mentioned, you will hear various accents, but I think "RP" English predominates, especially among the announcers, newsreaders and continuity people. There is a wide variety of programmes; quite a lot of news, but it's not all news by any means. There are documentaries, plays (drama), and "magazine" type programmes.

Then there is BBC Radio 4 Extra. This is a mixture of drama and comedy. Mostly things that have appeared on Radio 4 in the past, or maybe other BBC radio station in the more distant past. Some are really old, but still favourites of listeners. And because they are old, you'll probably hear more old-fashioned RP if that's what you want, although there will be some regional accents.

There is also World Service, obviously aimed at overseas listeners. I haven't listened to it for a while, but it always used to have a rather "old fashioned" sound to it, like the old BBC Home Service of the 1950s or so.
But it has been somewhat modernised in recent years I think, although there will still be plenty of "RP".

My advice would be to go to the BBC Sounds website, and browse through the schedules for those 3 stations and see if anything appeals, and give it a try.

e.g. if you like Sherlock Holmes, here are some classic recordings from the 1960s:

Something slightly more modern: (although set in the 1950s, but the recording is relatively recent):

(First of 3 episodes; follow the links to the other two). i listened to all of those and found it pretty interesting. Weird, but interesting. Charles Dance is RP personified. The character "Nicholas" is also RP, as are the two girls on the island. However, you will also hear an Australian girl, and you should be able to hear the difference in accent quite easily.

It's funny you mentioned Sherlock Holmes, because this whole thread was already making me think of Sherlock in both Sherlock (BBC) and Elementary; in both of them he has learned to mimic various accents and uses them in disguises. I personally have no ability to do accents beyond mimicking a specific sentence or phrase, but it's a skill I very much wish I had!

Also Sherlock Holmes has recently become a pretty intense special interest for me, so thank you for linking to more Holmesian content!

If you want to explore different types of British English, including RP or Queen's English, Cockney and Estuary English and the differences between them, I highly recommend the YouTube channel Eat, Sleep, Dream English with Tom. Ha has a lot of videos explaining different British accents and how they sound Here is just one example of a somewhat humorous but instructive video about the sounds and expressions that make conservative RP distinctive:
