Open back rounded vowel

The open back rounded vowel, or low back rounded vowel, is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɒ⟩. It is called Latin turned alpha being a rotated version of Latin alpha. It seems a "turned script a", being a rotated version of "script (cursive) a", which is the variant of a that lacks the extra stroke on top of a "printed a". Latin turned alpha a ⟨ɒ⟩ has its linear stroke on the left, whereas Latin alpha a ⟨ɑ⟩ has its linear stroke on the right.

The open back rounded vowel, or low back rounded vowel,1 is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɒ⟩. It is called Latin turned alpha being a rotated version of Latin alpha. It seems a "turned script a", being a rotated version of "script (cursive) a", which is the variant of a that lacks the extra stroke on top of a "printed a". Latin turned alpha aɒ⟩ has its linear stroke on the left, whereas Latin alpha aɑ⟩ (for its unrounded counterpart) has its linear stroke on the right.

Features

  • Its vowel height is open, also known as low, which means the tongue is positioned far from the roof of the mouth – that is, low in the mouth.
  • Its vowel backness is back, which means the tongue is positioned back in the mouth without creating a constriction that would be classified as a consonant.
  • Its place of articulation is pharyngeal, which means it is articulated with the tongue root against the back of the throat (the pharynx).
  • It is rounded, which means that the lips are rounded rather than spread or relaxed.

Occurrence

Language Word IPA Meaning Notes
Afrikaans Standard2 daar [dɒːr] 'there' Fully back. Used by some speakers, particularly young female speakers of northern accents. Other speakers use an unrounded vowel [ɑː ~ ɑ̟ː].2 See Afrikaans phonology
Assamese (kor) [kɒ̹ɹ] 'to do' An "over-rounded" [ɒ̹], with rounding as strong as that for [u].3 May also be transcribed [ɔ].
Bulgarian Some Rhodopean dialects мъж (măž) [ˈmɒʃʲ] 'man' Found as the unification of the Proto-Slavic *ǫ, *ę, *ъ and *ь. Standard Bulgarian has /ɤ̞/ for *ǫ and *ъ and /ɛ/ for *ę and *ь.
Dutch Some dialects4 bot [bɒt] 'bone' Some non-Randstad dialects,4 for example those of Den Bosch and Groningen. It is open-mid [ɔ] in standard Dutch.
English South African5 not [nɒ̜̈t] 'not' Near-back and weakly rounded.5 Some younger speakers of the General variety may actually have a higher and fully unrounded vowel [ʌ̈].5 See South African English phonology
Conservative Received Pronunciation6 [nɒt] Somewhat raised. Contemporary RP speakers pronounce a closer vowel [ɔ]. It is proposed that the /ɒ/ vowel of Conservative RP, which is normally described as a rounded vowel, is pronounced by some speakers without rounded lips for whom the characteristic quality is rather one of sulcality.7 See English phonology
Northern English8 May be somewhat raised and fronted.8
Canadian9 Lot and thought have the same vowel in Canadian English; see cotcaught merger.
thought [θɒt] 'thought'
General American Vowel /ɔ(:)/ is lowered (phonetic realization of /ɔ(:)/ is much lower in GA than in RP). However, "short o" before r before a vowel (a short o sound followed by r and then another vowel, as in orange, forest, moral, and warrant) is realized as [oɹ~ɔɹ].
Inland Northern American10 See Northern Cities Vowel Shift
Indian11 [t̪ʰɒʈ] /ɒ/ and /ɔː/ differ entirely by length in Indian English.
Welsh1213 [θɒːt] Open-mid in Cardiff; may merge with // in northern dialects.

Many Swiss dialects15 maane [ˈmɒːnə] 'remind' The example word is from the Zurich dialect, in which [ɒː] is in free variation with the unrounded [ɑː].16

Near-open back rounded vowel

Near-open back rounded vowel
ɒ̝
ɔ̞

In some languages there is the near-open back rounded vowel (a sound between cardinal ⟨ɒ⟩ and ⟨ɔ⟩), which can be transcribed in IPA with [ɒ̝] or [ɔ̞].

Features

  • Its vowel height is near-open, also known as near-low, which means the tongue is positioned similarly to an open vowel, but is slightly more constricted – that is, the tongue is positioned similarly to a low vowel, but slightly higher.
  • Its vowel backness is back, which means the tongue is positioned back in the mouth without creating a constriction that would be classified as a consonant.
  • Its place of articulation is pharyngeal, which means it is articulated with the tongue root against the back of the throat (the pharynx).
  • It is rounded, which means that the lips are rounded rather than spread or relaxed.
