The open-mid back unrounded vowel, or low-mid back unrounded vowel,[1] is a type of vowel sound, used in some spokenlanguages. Acoustically it is an open-mid back-central unrounded vowel.[2] The symbol in the International Phonetic Alphabet that represents this sound is ⟨ʌ⟩, graphically a rotated lowercase "v" (called a turned V but created as a small-capital ⟨ᴀ⟩ without the crossbar). Both the symbol and the sound are commonly referred to as either a wedge, a caret, or a hat. In transcriptions for English, this symbol is commonly used for the near-open central unrounded vowel, and in transcriptions for Danish, it is used for the (somewhat mid-centralized) open back rounded vowel.
Its vowel backness is back, which means the tongue is positioned as far back as possible in the mouth without creating a constriction that would be classified as a consonant. Unrounded back vowels tend to be centralized, which means that often they are in fact near-back.
It is unrounded, which means that the lips are not rounded.
Allophone of /ʌ, ʌː/ (which phonetically are central [ɜ, ɜː])[16] before and after /ŋ, kʰ, k, χ, ʁ/. Exact backness varies; it is most posterior before /χ, ʁ/.[17]
Nasalized. Phonetic realization of the sequence /am/, may be [õ] or [ã] instead.[27] See Tamil phonology
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 unrounded vowel). Daniel Jones reports his speech (southern British), as having an advanced back vowel [ʌ̟] 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].[28] In American English varieties, e.g. the West and Midwest, and the urban South, the typical phonetic realization of the phoneme /ʌ/ is an open-mid central [ɜ].[29][30] 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.[31][32] 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.[33]
