American English (AmE), sometimes called United States English or U.S. English, is the set of varieties of the English language native to the United States. English is the most widely spoken language in the United States; the de facto common language used in government, education and commerce; and an official language of most U.S. states. Since the late 20th century, American English has become the most influential form of English worldwide.
South African English is the set of English language dialects native to South Africans.
Non-native pronunciations of English result from the common linguistic phenomenon in which non-native speakers of any language tend to transfer the intonation, phonological processes and pronunciation rules of their first language into their English speech. They may also create innovative pronunciations not found in the speaker's native language.
The phonology of the open back vowels of the English language has undergone changes both overall and with regional variations, through Old and Middle English to the present. The sounds heard in modern English were significantly influenced by the Great Vowel Shift, as well as more recent developments in some dialects such as the cot–caught merger.
Southern American English or Southern U.S. English is a regional dialect or collection of dialects of American English spoken throughout the Southern United States, though concentrated increasingly in more rural areas, and spoken primarily by White Southerners. In terms of accent, its most innovative forms include southern varieties of Appalachian English and certain varieties of Texan English. Popularly known in the United States as a Southern accent or simply Southern, Southern American English now comprises the largest American regional accent group by number of speakers. Formal, much more recent terms within American linguistics include "Southern White Vernacular English" and "Rural White Southern English".
While many languages have numerous dialects that differ in phonology, contemporary spoken Arabic is more properly described as a continuum of varieties. This article deals primarily with Modern Standard Arabic (MSA), which is the standard variety shared by educated speakers throughout Arabic-speaking regions. MSA is used in writing in formal print media and orally in newscasts, speeches and formal declarations of numerous types.
English phonology is the system of speech sounds used in spoken English. Like many other languages, English has wide variation in pronunciation, both historically and from dialect to dialect. In general, however, the regional dialects of English share a largely similar phonological system. Among other things, most dialects have vowel reduction in unstressed syllables and a complex set of phonological features that distinguish fortis and lenis consonants.
The close and mid-height front vowels of English have undergone a variety of changes over time and often vary by dialect.
There are a variety of pronunciations in Modern English and in historical forms of the language for words spelled with the letter ⟨a⟩. Most of these go back to the low vowel of earlier Middle English, which later developed both long and short forms. The sound of the long vowel was altered in the Great Vowel Shift, but later a new long A developed which was not subject to the shift. These processes have produced the main four pronunciations of ⟨a⟩ in present-day English: those found in the words trap, face, father and square. Separate developments have produced additional pronunciations in words like wash, talk and comma.
The International Phonetic Alphabet (IPA) can be used to represent sound correspondences among various accents and dialects of the English language.
The TRAP–BATH split is a vowel split that occurs mainly in Southern England English, Australian English, New Zealand English, Indian English, South African English and to a lesser extent in some Welsh English as well as older Northeastern New England English by which the Early Modern English phoneme was lengthened in certain environments and ultimately merged with the long of PALM. In that context, the lengthened vowel in words such as bath, laugh, grass and chance in accents affected by the split is referred to as a broad A. Phonetically, the vowel is in Received Pronunciation (RP), Cockney and Estuary English; in some other accents, including Australian and New Zealand accents, it is a more fronted vowel and tends to be a rounded and shortened in Broad South African English. A trap–bath split also occurs in the accents of the Middle Atlantic United States, but it results in very different vowel qualities to the aforementioned British-type split. To avoid confusion, the Middle Atlantic American split is usually referred to in American linguistics as a 'short-a split'.
South Australian English is the variety of English spoken in the Australian state of South Australia. As with the other regional varieties within Australian English, these have distinctive vocabularies. To a lesser degree, there are also some differences in phonology (pronunciation). There is also significant influence from minority groups within the state, such as the ethnic German community, a sizeable amount of which speak Barossa German.
Australian English (AuE) is a non-rhotic variety of English spoken by most native-born Australians. Phonologically, it is one of the most regionally homogeneous language varieties in the world. Australian English is notable for vowel length contrasts which are absent from most English dialects.
North American English regional phonology is the study of variations in the pronunciation of spoken North American English —what are commonly known simply as "regional accents". Though studies of regional dialects can be based on multiple characteristics, often including characteristics that are phonemic, phonetic, lexical (vocabulary-based), and syntactic (grammar-based), this article focuses only on the former two items. North American English includes American English, which has several highly developed and distinct regional varieties, along with the closely related Canadian English, which is more homogeneous geographically. American English and Canadian English have more in common with each other than with varieties of English outside North America.
Australian English is relatively homogeneous when compared with British and American English. The major varieties of Australian English are sociocultural rather than regional. They are divided into 3 main categories: general, broad and cultivated.
Older Southern American English is a diverse set of American English dialects of the Southern United States spoken most widely up until the American Civil War of the 1860s, before gradually transforming among its White speakers, first, by the turn of the 20th century, and, again, following the Great Depression, World War II, and, finally, the Civil Rights Movement. By the mid-20th century, among White Southerners, these local dialects had largely consolidated into, or been replaced by, a more regionally unified Southern American English. Meanwhile, among Black Southerners, these dialects transformed into a fairly stable African-American Vernacular English, now spoken nationwide among Black people. Certain features unique to older Southern U.S. English persist today, like non-rhoticity, though typically only among Black speakers or among very localized White speakers.
The English language spoken and written in England encompasses a diverse range of accents and dialects. The language forms part of the broader British English, along with other varieties in the United Kingdom. Terms used to refer to the English language spoken and written in England include English English and Anglo-English.
The Cardiff accent, also known as Cardiff English, is the regional accent of English, and a variety of Welsh English, as spoken in and around the city of Cardiff, and is somewhat distinctive in Wales, compared with other Welsh accents. Its pitch is described as somewhat lower than that of Received Pronunciation, whereas its intonation is closer to dialects of England rather than Wales.
The distinction between rhoticity and non-rhoticity is one of the most prominent ways in which varieties of the English language are classified. In rhotic accents, the sound of the historical English rhotic consonant,, is preserved in all pronunciation contexts. In non-rhotic accents, speakers no longer pronounce in postvocalic environments: when it is immediately after a vowel and not followed by another vowel. For example, in isolation, a rhotic English speaker pronounces the words hard and butter as /ˈhɑːrd/ and /ˈbʌtər/, but a non-rhotic speaker "drops" or "deletes" the sound and pronounces them as /ˈhɑːd/ and /ˈbʌtə/. When an r is at the end of a word but the next word begins with a vowel, as in the phrase "better apples," most non-rhotic speakers will preserve the in that position since it is followed by a vowel in this case.
This article covers the phonological system of South African English (SAE) as spoken primarily by White South Africans. While there is some variation among speakers, SAE typically has a number of features in common with English as it is spoken in southern England, such as non-rhoticity and the TRAP–BATH split.
