Learn English Pronunciation.

Pronunciation can be a tricky matter when it comes to the English language. Unlike with languages like Hindi and Tamil, letters in English take on multiple phonetic forms (think of the a in‘can’and the a in‘war’); thus, the concept of pronouncing a word the way it is spelled does not apply. This is partly the result of derivation; English is a derivative language. It means that many of its words and phrases have been borrowed from other languages (cafe, boutique, cocoa).
The unpredictability that results from being a derivative language, makes pronunciation in English difficult to master. A written course is possibly the least helpful way to go about it. It is through continued contact with English speakers and practice that one’s pronunciation improves. Watching English-language films, TV shows, and news channels is also very useful. Both methods, however, require conscious effort. One must pay close attention while conversing with someone who is fluent and while watching English-language film or TV productions, and through practice, make correct-sounding speech a matter of habit.
There are, however, some guidelines that we can provide on pronunciation that should help in giving you an idea of the contours of spoken English:
