I don't know about you, but I have a very hard time understanding a lot of Indian accents specifically because of the unfamiliar stress patterns. (That, and their avoidance of aspirated consonants, which drives me crazy.)
tbh I find the unfamiliar stress patterns of reasonably fluent Indian English speakers a lot less problematic than some of the quirks my fellow Brits' stronger regional accents! The tendency to enunciate syllables we often mash together actually tends to be clearer
Yeah I do decent with Indian accents as well. And I have more trouble with Chinese accents and many British accents. But I mostly can’t stand the southern English and their inability to pronounce the letter R. It sounds like someone with a speech impediment. As an American I greatly prefer speaking to a Scot or Irishman.
And the closer you get to London the more the English have a French culture. By that I mean an inferiority/superiority complex. They’re always better than everyone else.
