Are there any dialects in American English?

American English has various dialects.

People in different parts of the United States have different accents, which are similar to dialects in different parts of China, but the difference is not too big relative to speaking English. People who speak Mandarin in northern China have their own accents.

American English tends to be conservative in phonology. Some people think that some rural accents in North America are the same as English in Elizabeth I's time. However, compared with the local accent of contemporary England, the standard American English in the midwest and north of the United States is closer to17th century English in pronunciation.

Differences in American English pronunciation;

The main reason for the conservative pronunciation of American English is the mixture of various dialects from the British Isles. Because of its close relationship with England, Britain was still in an advantageous position at that time, and the American East Coast accent changed with the development of British English. There is relatively little contact between the inland areas of the United States and Britain, which largely retains the original accent.

Most contemporary North American English has a rolling tongue (also called rolling tongue), and the letter R should also be pronounced before the consonant; Although there is no tongue curl in British English today, it has spread all over England in the17th century. Influenced by Irish English and Scottish English, tongue rolling has been further developed in the United States.

In most North American English dialects, the letter R is pronounced as a rolling semi-vowel, not a trill. The sound "er" in fur (stressed) and butter (unstressed) is marked as [? ] and [? ], but it is an r vowel in American English.

Traditionally, most people think that "American Putonghua" and its accent (GeneralAmerican, sometimes called "standard Midwest American") are unwritten standard dialects and accents.

However, many linguists claim that since 1960s or 1970s, California English has become the de facto standard because of its core position in American entertainment industry. Others think that although the entertainment circle is in California, it still uses Midwest American English. It is generally believed that some features of California English, especially the phenomenon of cot-catch merger, do not belong to the standard category.
