Contents Introduction Chapter Theoretical background of English pronunciation

Conclusion
English is the national language of England proper the USA, Australia and some provinces of Canada. It was also at different times imposed on the inhabitants of the former and present British colonies and protectorates as well as other Britain- and USA-dominated territories, where the population has always stuck to its own mother tongue.
The English language has been developing during all its history. Today, one may visit almost any country with knowing only two languages - his or her mother tongue and English - and that will be enough for successful interaction. Another question is, whether one knows the accent and peculiarities of that English people in that country use. That is why the problem of the English language varieties exists nowadays.
In considering the history and development of the English language we may maintain that a regional variety of English is a complex of regional standard norms and dialects. Owing to specific ways of development, every regional variety is characterized by a set of features identical to a variety of English.
The comparative analysis of the phonetic system of the regional varieties of English pronunciation shows the differences in the pronunciation in the system of consonant and vowel phonemes.
American English and British English are two equitable variants of the same language, because their structural peculiarities, especially their word-formation system, syntax and morphology, as well as their word-stock and phonetic system are essentially the same. American standard is a slight modification of the norms accepted on the British Isles.
In the course of the work the following conclusions were made: despite the influence of other languages and their families, the English language saved its unique structure and individuality, having avoided the possibility to be the source for new languages origin.
Since the English language was given a spread all over the world, it possesses a great influence on other tongues and became a perfect international language in our present life.
