The open-mid back unrounded vowel, or low-mid back unrounded vowel, is a type of vowel sound, used in some spokenlanguages. The symbol in the International Phonetic Alphabet that represents this sound is 〈ʌ〉, graphically a rotated lowercase vee (called a turned V, though it was created as a small-capital 〈ᴀ〉 without the crossbar), and both the symbol and the sound are commonly referred to as either a wedge, a caret, or a hat. In transcriptions for some languages (including several dialects of English), this symbol is also used for the near-open central vowel.
The IPA prefers the terms "close" and "open" for vowels, and the name of the article follows this. However, a large number of linguists[who?], perhaps a majority, prefer the terms "high" and "low".
Centralized. It's a common realization of /ɒ/ for younger speakers in Cape Town and Natal. It corresponds to a weakly rounded [ɒ̈] in all other South African dialects. In addition, this realisation of /ɒ/ is often found in non-Bostonian New England accents.
Before World War II, the /ʌ/ of Received Pronunciation was phonetically close to a back vowel [ʌ]; this sound has since shifted forward towards [ɐ] (a near-open central vowel). Daniel Jones reports his speech (southern British), as having an advanced back vowel [ʌ̘] between his central /ə/ and back /ɔ/; however, he also reports that other southern speakers had a lower and even more advanced vowel approaching cardinal [a]. In American English varieties, e.g., the West and Midwest, and the urban South, the typical phonetic realization of the phoneme /ʌ/ is a central vowel that can be transcribed as [ɜ] (open-mid central). Truly backed variants of /ʌ/ that are phonetically [ʌ] can occur in Inland Northern American English, Newfoundland English, Philadelphia English, some African-American Englishes, and (old-fashioned) white Southern English in coastal plain and Piedmont areas. Despite this, the letter 〈ʌ〉 is still commonly used to indicate this phoneme, even in the more common varieties with central variants [ɐ] or [ɜ]. This may be due to both tradition as well as the fact that some other dialects retain the older pronunciation.
