A vowel shift is a systematic sound change in the pronunciation of the vowel sounds of a language.
The best-known example in the English language is the Great Vowel Shift, which began in the 15th century. The Greek language also underwent a vowel shift near the beginning of the Common Era, which included iotacism. Among the Semitic languages, the Canaanite languages underwent a shift in which Proto-Semitic *ā became ō in Proto-Canaanite (a language likely very similar to Biblical Hebrew).
A vowel shift can involve a merger of two previously different sounds, or it can be a chain shift.
One of the several major vowel shifts that is currently underway in the US is the Northern Cities Vowel Shift. This change pattern is characterized by the longer and lower vowels moving forward and upward, while the shorter vowels move downward and backward. This vowel rotation, for example, is noticeable as the vowel sound in “coffee” is moving toward the vowel in “father.” While there are undoubtedly several other change patterns that define the shift in the Northern Cities, they are diffusing throughout the North in a unique manner, and are inherently different from dialect shifts taking place in other regions.
In addition to the Northern Cities Vowel Shift, the dialect change patterns that are taking place in the South also indicate undeniable pronunciation changes in the region. In contrast to the changes in the North, however, the Southern Cities Vowel Shift is characterized by the shorter, front vowels moving upward and adopting the characteristics of traditionally longer vowels. To exemplify this Southern vowel change, the vowel in the word “bed” is commonly used, as the “e” moves upward and gains a glide and causes the word to be pronounced more like “bayd.”
California Vowel Shift (CVS) has several identifying features. These include the low back vowel mergers of words such as bought and bot, fronting of back vowels /oʊ/ as in coat and /ʊ/ in nook or look, as well as that which is found in words such as loot or hoot. Another identifying feature of CVS is the raising or backing of the vowel /æ/ such as that found in cat, depending on its linguistic environment and whether it is pre-nasal or not. [1] Since California is such a large state, and home to millions of people from diverse ethnic origins and backgrounds, California has seen vowel shifts within its own borders, allowing linguists to see phonological differences between Northern, Southern and Bay Area regions of California. While linguists recognize that not all native Californians have shifted their vowels to these placements within their speech acts, it is prevalent enough to recognize the chain shift that is occurring in the largest Western state.
In Northern California, there is a chain vowel shift occurring. Short front vowels that used to be higher are shifting to lower vowel spaces in native Northern California speech acts involving the vowels /i/, /ɛ/ and /æ/. Additionally, Northern California speech acts are centralizing the sound that occurs in words such as boat (/oʊ/). [2] These shifts in vowel shortening and centralization, while not entirely unique to the region of Northern California natives, does represent the most obvious changes that are occurring within the area in regards to native speech acts.
The region of California that includes the Silicon Valley and the populous cities of San Francisco, Oakland and San Jose utilizes the same speech vowel shifts as their native Northern California neighbors in regards to vowel shortening and centralization of the diphthong in words such as boat or coat. However, this area is uniquely influenced by the acoustic accouterments associated with the gay identity which include fronting of back vowels and merging vowel sounds found in words such as cot and caught. [3] Native Bay Area residents tend to have a more intensive vowel shift in regards to the components that comprise CVS. These shifts include changes in voice and intonation.
Due to the increasing migration from multiple Latin American countries, especially from its southern neighbor Mexico, California is influenced in speech patterns and speech acts from this population. Changes in native California speech due to this influence include a shift from /ɪŋ/ to /iŋ/ in California English. [4] These changes are most obvious in areas with large Latin American communities.
The Canadian Vowel Shift can be described to have a lot of systematic changes, however one of the main ones can be found in the lowering of /ɪ/, /ɛ/, /æ/. In the early stages of the Canadian shift there is a stabilizing in the retraction of the vowel /æ/. The first reported case of the vowels /ɪ/, /ɛ/, and /æ/ in Canadian English was involved in a chain shift, which can be described as the lowering of the front lax vowels over time. [5]
There is another characteristic found in Canadian English called Canadian Raising. This feature includes the vowel diphthongs onsets of /aj/ and /aw/ raise to mid vowels when they precede voiceless obstruents (the sounds /p/, /t/, /k/, /s/, and /f/). Canadian pronunciation of "about" often sounds like "aboot", pronunciation of /aw/ is articulated with the tongue in a low position, and because it raises to a mid position in Canadian English when the vowel precedes the voiceless obstruents listed above. Speakers of other varieties of English will immediately detect the vowel raising, but will sometimes think that the vowel has raised farther than it actually does, all the way to /u/. The raised vowels /aɪ/ typically raises [ɐɪ], while the raised variant of /aʊ/ differs by dialects in Canada, with [ɐʊ~ʌʊ] more common in Western Canada and a fronted variant [əʊ~ɛʊ] is mostly heard in Central Canada. [6] The open vowel component of the diphthongs changes to a mid vowel ([ʌ], [ɐ], [ɛ] or [ə]).
In recent decades, Standard Southern British (SSB) has undergone an “anti-clockwise” vowel shift. The front vowels are lower ([e] has lowered to [ɛ] and [æ] to [a]), the starting vowel of the /aɪ/ diphthong is backer (from [a] to [ɑ] or [ʌ]), back vowels are higher ([ɒ] has raised to [ɔ] and [ɔː] to [oː]) and [uː] has fronted and diphthongized to [ʉw]. [7]
The Great Vowel Shift was a series of changes in the pronunciation of the English language that took place primarily between 1400 and 1700, beginning in southern England and today having influenced effectively all dialects of English. Through this vowel shift, the pronunciation of all Middle English long vowels was changed. Some consonant sounds also changed, particularly those that became silent; the term Great Vowel Shift is sometimes used to include these consonantal changes.
A diphthong, also known as a gliding vowel, is a combination of two adjacent vowel sounds within the same syllable. Technically, a diphthong is a vowel with two different targets: that is, the tongue moves during the pronunciation of the vowel. In most varieties of English, the phrase "no highway cowboy" has five distinct diphthongs, one in every syllable.
Canadian raising is an allophonic rule of phonology in many varieties of North American English that changes the pronunciation of diphthongs with open-vowel starting points. Most commonly, the shift affects or, or both, when they are pronounced before voiceless consonants. In North American English, and usually begin in an open vowel [~], but through raising they shift to, or. Canadian English often has raising in words with both and, while a number of American English varieties have this feature in but not. It is thought to have originated in Canada in the late 19th century.
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.
In historical linguistics, a chain shift is a set of sound changes in which the change in pronunciation of one speech sound is linked to, and presumably causes, a change in pronunciation of other sounds. The sounds involved in a chain shift can be ordered into a "chain" in such a way that after the change is complete, each phoneme ends up sounding like what the phoneme before it in the chain sounded like before the change. The changes making up a chain shift, interpreted as rules of phonology, are in what is termed counterfeeding order.

California English collectively refers to varieties of American English native to California. As California became one of the most ethnically diverse U.S. states, English speakers from a wide variety of backgrounds began to pick up different linguistic elements from one another and also develop new ones; the result is both divergence and convergence within Californian English. However, linguists who studied English before and immediately after World War II tended to find few, if any, patterns unique to California, and even today most California English still largely aligns to a General or Western American accent. Still, certain newer varieties of California English have been gradually emerging since the late 20th century.
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.
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.
High Tider, Hoi Toider, or High Tide English is an American English dialect, or family of dialects, spoken in very limited communities of the South Atlantic United States, particularly several small islands and coastal townships. The exact areas include the rural "Down East" region of North Carolina, which encompasses the Outer Banks and Pamlico Sound—specifically Atlantic, Davis, Sea Level, and Harkers Island in eastern Carteret County, the village of Wanchese, and also Ocracoke—plus the Chesapeake Bay, such as Smith Island in Maryland, as well as Guinea Neck and Tangier Island in Virginia. High Tider has been observed as far west as Bertie County, North Carolina; the term is also a local nickname for any native resident of these regions.
Pacific Northwest English is a variety of North American English spoken in the U.S. states of Washington and Oregon, sometimes also including Idaho and the Canadian province of British Columbia. Due to the internal diversity within Pacific Northwest English, current studies remain inconclusive about whether it is best regarded as a dialect of its own, separate from Western American English or even California English or Standard Canadian English, with which it shares its major phonological features. The dialect region contains a highly diverse and mobile population, which is reflected in the historical and continuing development of the variety.
The low-back-merger shift is a chain shift of vowel sounds found in several dialects of North American English, beginning in the last quarter of the 20th century and most significantly involving the low back merger accompanied by the lowering and backing of the front lax vowels.
Inland Northern (American) English, also known in American linguistics as the Inland North or Great Lakes dialect, is an American English dialect spoken primarily by White Americans in a geographic band reaching from the major urban areas of Upstate New York westward along the Erie Canal and through much of the U.S. Great Lakes region. The most distinctive Inland Northern accents are spoken in Chicago, Milwaukee, Detroit, Cleveland, Buffalo, Rochester, and Syracuse. The dialect can be heard as far west as eastern Iowa and even among certain demographics in the Twin Cities, Minnesota. Some of its features have also infiltrated a geographic corridor from Chicago southwest along historic Route 66 into St. Louis, Missouri; today, the corridor shows a mixture of both Inland North and Midland American accents. Linguists often characterize the western Great Lakes region's dialect separately as North-Central American English.
English diphthongs have undergone many changes since the Old and Middle English periods. The sound changes discussed here involved at least one phoneme which historically was a diphthong.
Western American English is a variety of American English that largely unites the entire Western United States as a single dialect region, including the states of California, Nevada, Arizona, Utah, New Mexico, Colorado, and Wyoming. It also generally encompasses Washington, Oregon, Idaho, and Montana, some of whose speakers are classified additionally under Pacific Northwest English.
Monophthongization is a sound change by which a diphthong becomes a monophthong, a type of vowel shift. It is also known as ungliding, as diphthongs are also known as gliding vowels. In languages that have undergone monophthongization, digraphs that formerly represented diphthongs now represent monophthongs. The opposite of monophthongization is vowel breaking.
This article covers the phonological system of New Zealand English. While New Zealanders speak differently depending on their level of cultivation, this article covers the accent as it is spoken by educated speakers, unless otherwise noted. The IPA transcription is one designed by Bauer et al. (2007) specifically to faithfully represent a New Zealand accent, which this article follows in most aspects.
The Atlas of North American English: Phonetics, Phonology and Sound Change is a 2006 book that overviews the pronunciation patterns (accents) in all the major dialect regions of the English language as spoken in urban areas of the United States and Canada. It is the result of a large-scale survey by linguists William Labov, Sharon Ash, and Charles Boberg. Speech data was collected, mainly during the 1990s, by means of telephone interviews with individuals in metropolitan areas in all regions of the U.S. and Canada. Using acoustic analysis of speech from these interviews, ANAE traces sound changes in progress in North American English, and defines boundaries between dialect regions based on the different sound changes taking place in them.
Standard Canadian English is the largely homogeneous variety of Canadian English that is spoken particularly across Ontario and Western Canada, as well as throughout Canada among urban middle-class speakers from English-speaking families, excluding the regional dialects of Atlantic Canadian English. Canadian English has a mostly uniform phonology and much less dialectal diversity than neighbouring American English. In particular, Standard Canadian English is defined by the cot–caught merger to and an accompanying chain shift of vowel sounds, which is called the Canadian Shift. A subset of the dialect geographically at its central core, excluding British Columbia to the west and everything east of Montréal, has been called Inland Canadian English. It is further defined by both of the phenomena that are known as Canadian raising : the production of and with back starting points in the mouth and the production of with a front starting point and very little glide that is almost in the Canadian Prairies.
Western New England English refers to the varieties of New England English native to Vermont, Connecticut, and the western half of Massachusetts; New York State's Hudson Valley also aligns to this classification. Sound patterns historically associated with Western New England English include the features of rhoticity, the horse–hoarse merger, and the father–bother merger, none of which are features traditionally shared in neighboring Eastern New England English. The status of the cot–caught merger in Western New England is inconsistent, being complete in the north of this dialect region (Vermont), but incomplete or absent in the south, with a "cot–caught approximation" in the middle area.
