“usually with a Hindu accent”
Do Hindus have an accent? Maybe a middle eastern country accent....
A lot of Hindus have accents, often quite rich ones, based on British English. Then, on its own, English lends itself to regionalisms, so if your ear was tuned to it enough, you might be able to distinguish all sorts of Indian English accents.
I knew of a college professor with such a finely tuned ear, who as late as the early 1960s, could talk with an American for a few minutes, and tell to within 50 miles where he had been raised. But even then he was aware that with radio and TV, regionalisms were collapsing into a “continental” American English.
Here is a gigantic .gif map of just the current major American dialects.
