Language (especially spoken language, most especially English) doesn't really have a "right" or "wrong." It has "likely to be understood by receiver" and "unlikely to be understood by receiver."
The real correct answer to anyone's "what's the right way to say...?" question is a probability distribution.
Language do have right and wrong pronunciation and, in many cases, it is also tied to the script. e.g. in Hindi position of tongue, lips and sound from vocal cord is defined for every phoneme.
That's why games like spelling bee make no sense because if you can hear the word, you can write it there is no ambiguity. Some may pronounce words it differently, but they are mostly different dialects. Or in some cases it is accepted as wrong but common pronunciation.
