Open back rounded vowel

The open back rounded vowel, or low back rounded vowel,[1] is a type of vowel sound, used in some spoken languages. Acoustically, it is a near-open or near-low back rounded vowel.[2] The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɒ⟩. It is called "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". Turned script aɒ⟩ has its linear stroke on the left, whereas "script a" ⟨ɑ⟩ (for its unrounded counterpart) has its linear stroke on the right.

A well-rounded [ɒ] is rare, but it is found in some varieties of English. In most languages with this vowel, such as English and Persian, the rounding of [ɒ] is slight, and in English at least, it is sulcal or "grooved". However, according to Ladefoged & Maddieson (1996), Assamese has an "over-rounded" [ɒ̹], with rounding as strong as that for [u].[3]

According to the phonetician Geoff Lindsey, ⟨ɒ⟩ may be an entirely superfluous IPA symbol, as the sound it represents is far too similar to the open-mid back rounded vowel [ɔ], which makes it unlikely that any language would contrast these two vowels phonemically. He also writes that the contemporary Standard Southern British (SSB) accent lacks [ɒ], having replaced it with the more common [ɔ] (a realization that is also found in e.g. Australia,[4][5] New Zealand[6] and Scotland),[7][8] and advocates for transcribing this vowel with the symbol ⟨ɔ⟩ in SSB.[7]

This is not to be understood as /ɒ/ having the same quality as /ɔː/ (which Lindsey transcribes with ⟨⟩),[7] as the latter vowel is true-mid [ɔ̝ː] in SSB,[9] a pronunciation that was established decades ago.[10] Lindsey also says that more open variants of /ɒ/ used formerly in SSB are satisfyingly represented by the symbols [ɔ̞] and [ɑ] in narrow phonetic transcription, and ⟨ɔ⟩ in phonemic/broad phonetic transcription. According to him, the endless repetition of the symbol ⟨ɒ⟩ in publications on BrE has given this vowel a familiarity out of all proportion to its scarcity in the world’s languages.[7]



IPA: Vowels
Front Central Back

Paired vowels are: unrounded  rounded

  • Its vowel height is open, also known as low, which means the tongue is positioned as far as possible from the roof of the mouth – that is, as low as possible in the mouth.
  • 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 rounded, which means that the lips are rounded rather than spread or relaxed.
