English phonology: English phonology refers to the study of English phonology (that is, phonetic system). Just like all languages, regardless of history, the pronunciation of spoken English varies from dialect to dialect.
This variation is particularly obvious in English, because it is widely used in English-speaking countries in Australia, Canada, the United States, New Zealand, Britain and the Caribbean, and is used as a mother tongue or a second language in every country in the world.
