Canadian raising

Canadian raising (also sometimes known as English diphthong raising

General American accents) have this feature in /aɪ/ but not /aʊ/. It is thought to have originated in Canada in the late 19th century.^[1]

In the U.S., aboot [əˈbut], an exaggerated version of the raised pronunciation of about [əˈbʌʊt], is a stereotype of Canadian English.^[2]

Although the symbol ⟨ʌ⟩ is defined as an open-mid back unrounded vowel in the International Phonetic Alphabet, ⟨ʌɪ⟩ or ⟨ʌʊ⟩ may signify any raised vowel that contrasts with unraised /aɪ/ or /aʊ/, when the exact quality of the raised vowel is not important in the given context.

Description

Examples of Canadian raising in American English

rider, writer

[ˈɹaɪɾɚ] without raising,
[ˈɹɐɪɾɚ] with it

high school

[ˈhɐɪskul] "secondary school" with raising,
[ˌhaɪ ˈskul] "school that is high up" without it

bowed, bout

[baʊd] without raising,
[bɜʊt] with it

about, a boot, a boat

[əˈbɜʊt] with raising,
compared with oo in [ə ˈbut]
and oh in [ə ˈbɤʊt]

Phonetic environment

In general, Canadian raising affects vowels before voiceless consonants like /f/, /θ/, /t/, and /s/. Vowels before voiced consonants like /v/, /ð/, /d/, and /z/ are usually not raised.

However, several studies indicate that this rule is not completely accurate, and have attempted to formulate different rules.

A study of three speakers in Meaford, Ontario, showed that pronunciation of the diphthong /aɪ/ fell on a continuum between raised and unraised. Raising is influenced by voicing of the following consonant, but it may also be influenced by the sound before the diphthong. Frequently the diphthong was raised when preceded by a coronal: in gigantic, dinosaur, and Siberia.^[3]

Raising before /r/, as in wire, iris, and fire, has been documented in some American accents.^[4]

Raising of /aɪ/ before certain voiced consonants is most prominent in the

phonemic split in these dialects; the distribution of the two sounds is becoming more unpredictable among younger speakers.^[5]

Raising can apply to compound words. Hence, the first vowel in high school [ˈhʌɪskul] as a term meaning "a secondary school for students approximately 14–18 years old" may be raised, whereas high school [ˌhaɪ ˈskul] with the literal meaning of "a school that is high (e.g. in elevation)" is unaffected. (The two terms are also distinguished by the position of the stress accent, as shown.) The same is true of "high chair".^[6]

However, frequently it does not. One study of speakers in Rochester, New York and Minnesota found a very inconsistent pattern of /aɪ/ raising before voiceless consonants in certain prefixes; for example, the numerical prefix bi- was raised in bicycle but not bisexual or bifocals. Likewise, the vowel was consistently kept low when used in a prefix in words like dichotomy and anti-Semitic. This pattern may have to do with stress or familiarity of the word to the speaker; however, these relations are still inconsistent.^[7]

In most dialects of North American English, intervocalic /t/ and /d/ are pronounced as an

pre-fortis clipping, in accents with raising, the words may be distinguished by their vowels: writer [ˈɹʌɪɾɚ], rider [ˈɹaɪɾɚ].^[8]

Result

The raised variant of /aɪ/ typically becomes [ɐɪ]. In most of Canada, the raised vowel is further front than /aɪ/,^[9] and in traditional New York City English, /aɪ/ is backed towards [ɑɪ] except before voiceless consonants, resulting in a distinction based more on frontness,^{[citation needed]} but in Philadelphia it may be more back.^[5]

The raised variant of /aʊ/ varies by dialect, with [ɐʊ~ʌʊ] more common in Western Canada and a fronted variant [ɜʊ~ɛʊ] commonly heard in Central Canada.^[2] In any case, the open vowel component of the diphthongs changes to a mid vowel ([ʌ], [ɐ], [ɛ] or [ə]).

Geographic distribution

Inside Canada

As its name implies, Canadian raising is found throughout most of Canada, though the exact phonetic quality of Canadian raising may differ throughout the country. In raised

Maritimes (particularly in Alberta): thus, [ʌʊ]. The first element tends to be the farthest forward in eastern and southern Ontario: thus, [ɛʊ~ɜʊ].^[10] Newfoundland English is the Canadian dialect that participates least in any conditioned Canadian raising, while Vancouver English may lack the raising of /aɪ/ in particular.^[11]

Outside Canada

Canadian raising is not restricted to Canada. Raising of both

Upper Midwest. South Atlantic English, New Orleans English,^[13] and the accents of England's Fens feature it as well.^{[clarification needed}

Raising of just

Upper Midwest, New England, New York City, and the mid-Atlantic areas of Pennsylvania (including Philadelphia), Maryland, and Delaware, as well as in Virginia.^[12]^[15]^[11] It is somewhat less common in the lower Midwest, the West, and the South. However, there is considerable variation in the raising of /aɪ/, and it can be found inconsistently throughout the United States.^[11]

The raising of

island of Ireland, in which /aɪ/ is split between the sound [ä(ː)e] (before voiced consonants or in final position) and the sound [ɛɪ~ɜɪ] (before voiceless consonants but also sometimes in any position); phonologist Raymond Hickey has described this Ulster raising as "embryonically the situation" for Canadian raising.^[16]
