In England, “sounding posh” is on a spectrum ranging from a simple well spoken Recieved Pronunciation from Emma Watson, to well spoken with more posh vowel and consonant sounds from Stephen fry’s RP, to the not at all natural sounding Upper RP that you’d get from the current King or Jacob Rees mogg (you can google him for how that sounds). What’s America’s equivalent would you say?
