Interesting comments: however, Hindi and Sanskrit are different languages, so surely you could accept that, jarring though it may be to your (native Hindi speaker) ear, it’s perfectly ok for people to pronounce the terminal vowels in Sanskrit, a different language? I’m no expert, just asking.

Being no expert, I also don’t know how much we really know about how Sanskrit was pronounced. The only people I’ve ever heard speaking it fluently are south Indian brahmins who are not “native speakers” either – to the extent that anybody was ever a “native speaker” of a languge as artificial and scholarly as classical Sanskrit. On the other hand, I’m aware that Panini and the strict rules for oral transmission of the Vedas make it one of the best documented and -preserved ancient languages, so I assume we do have a pretty reasonable idea of how it was pronounced.

Anyway, I’m a Brit and we traditionally don’t care about pronouncing ancient languages correctly. Our Latin pronunciation, for example, apparently used to be famously weird. We call Cicero neither “Kikero” (presumably correct Latin?) nor “Chichero” (modern Italian) but “Sisero”.

I’m rambling a bit, but I suppose my point if any is: you ought to accept either modern Hindi pronunciation or (some kind of honest attempt at) Sanskrit pronunciations as “correct”. Would be interested to hear more about your opinion on the matter.
