Not all speakers of English pronounce it in the same way. Even between the countries where English is the first language of the majority of population there are considerable differences, and we can distinguish between the pronunciation of 'British English', 'American English', 'Australian English', 'South African English', and so on.

One very interesting question that is often asked is: where do different dialects come from? Why are there dialects? The answer is that English, like all other languages in the world, is constantly changing, and that different changes take place in different parts of the country.
