These charts give a diaphoneme for each sound, followed by its realization in different dialects. The symbols for the diaphonemes are given in bold, followed by their most common phonetic values.
Abbreviations list
The following abbreviations are used in this article for regional varieties of English:
^/d/ is pronounced [ɾ] if preceded and followed by vowels in GA and Australian English.
^The labiodental fricative /f/ is often pronounced as bilabial [ɸ] after the bilabials /p/, /b/, and /m/, as in up-frontGA:[ʌpˈɸɹʌnt], Cub fanGA:[ˈkʰʌbɸæn], tomfooleryGA:[ˌtʰɑmˈɸuɫəɹi].
^The labiodental fricative /v/ is often pronounced as bilabial [β] after the bilabials /p/, /b/, and /m/, as in upvoteGA:[ˈʌpβəʊt], obviateGA:[ˈɑbβiˌeɪt], HumveeGA:[ˈhʌmβi].
^/θ/ is pronounced as a dental stop [t̪] in Irish English, Newfoundland English, Indian English, and New York English, merges with /f/ in some varieties of English English, and merges with /t/ in some varieties of Caribbean English. The dental stop [t̪] also occurs in other dialects as an allophone of /θ/.
^/ð/ is pronounced as a dental stop [d̪] in Irish English, Newfoundland English, Indian English, and New York English, merges with /v/ in some varieties of English English, and merges with /d/ in some varieties of Caribbean English. [d̪] also occurs in other dialects as an allophone of /ð/.
^The glottal fricative /h/ is often pronounced as voiced [ɦ] between vowel sounds and after voiced consonants. Initial voiced [ɦ] occurs in some accents of the Southern Hemisphere.
^/h/ is pronounced [ç] before the palatal approximant /j/, sometimes even replacing the cluster /hj/, and sometimes before high front vowels.
^The bilabial nasal /m/ is often pronounced as labiodental [ɱ] before /f/ and /v/, as in symphonyGA:[ˈsɪɱfəni], circumventGA:[ˌsɝkəɱˈvɛnt], some valueGA:[ˌsʌɱ‿ˈvæɫju̟].
^In some dialects, such as Brummie, words like ringer[ˈɹɪŋə], sing[sɪŋ], which have a velar nasal [ŋ] in most dialects, are pronounced with an additional /ɡ/, like "finger": [ˈfɪŋɡə].
^Velarized [ɫ] traditionally does not occur in Irish English; clear or plain [l] does not occur in Australian, New Zealand, Scottish, or American English. RP, some other English accents, and South African English, however, have clear [l] in syllable onsets and dark [ɫ] in syllable rimes.
^ abcSonorants are voiceless after a fortis (voiceless) stop at the beginning of a stressed syllable.
^L-vocalization in which l is pronounced as a kind of a back vowel ([ɤ] or [o], or non-syllabic [ɤ̯,o̯], forming a diphthong with the preceding vowel) occurs in New Zealand English and many regional accents, such as African-American Vernacular English, Cockney, New York English, Estuary English, Pittsburgh English, Standard Singapore English.
^/r/ is pronounced as a tap [ɾ] in some varieties of Scottish, Irish, Indian, Welsh, Northern England and South African English.
^The alveolar trill [r] only occurs in some varieties of Scottish, Welsh, Indian and South African English.
^R-labialization, in which r is pronounced as [ʋ], is found in some accents in Southern England.
In the vowels charts, a separate phonetic value is given for each major dialect, alongside the words used to name their corresponding lexical sets. The diaphonemes for the lexical sets given here are based on RP and General American; they are not sufficient to express all of the distinctions found in other dialects, such as Australian English.
The groups are defined such that no mergers of each group's sets take place outside them.[disputed – discuss] Note that in most cases, the first set in the group will never merge with the last set, similar to how the furthest points of a dialect continuum are not mutually intelligible.
^In American accents without the cot–caught merger, CLOTH words (usually words with a vowel written ⟨o⟩ preceding the fricatives /f/, /θ/ and /s/ and the velar nasal /ŋ/, e.g. off, cloth, boss, long), are pronounced with the vowel of THOUGHT, rather than the vowel of LOT as is the case in most other dialects of English, see Lot–cloth split. In American accents with the cot–caught merger (about half of today's speakers), LOT, CLOTH and THOUGHT all have the same vowel.
^ɒ~ɔ occurs in American accents without the cot–caught merger (about half of today's speakers); the rest have ɑ.
^This is a compromise IPA transcription, which covers most dialects of English.
^ abcdSome dialects of North American English have a vowel shift called Canadian raising, in which the first element of the diphthongs /aɪ,aʊ/ is raised in certain cases, yielding [ʌɪ̯,ʌʊ̯] or [əɪ̯,əʊ̯]. Canadian English has raising of both diphthongs, but most dialects in the United States only have raising of /aɪ/. In monosyllables, raising occurs before voiceless consonants, so right[ɹʌɪ̯t] and out[ʌʊ̯t] have raised vowels, but eyes[aɪz] and loud[laʊd] do not.
