A back vowel is any in a class of vowel sound used in spoken languages. The defining characteristic of a back vowel is that the tongue is positioned as far back as possible in the mouth without creating a constriction that would be classified as a consonant. Back vowels are sometimes also called dark vowels because they are perceived as sounding darker than the front vowels.
The back vowels that have dedicated symbols in the International Phonetic Alphabet are:
- close back unrounded vowel [ɯ]
- close back protruded vowel [u]
- close-mid back unrounded vowel [ɤ]
- close-mid back rounded vowel [o]
- open-mid back unrounded vowel [ʌ]
- open-mid back rounded vowel [ɔ]
- open back unrounded vowel [ɑ]
- open back rounded vowel [ɒ]
There also are back vowels that don't have dedicated symbols in the IPA:
- close back compressed vowel [ɯᵝ] or [uᵝ]
- mid back unrounded vowel [ɤ̞] or [ʌ̝] (normally written ⟨ɤ⟩ as if it were close-mid)
- mid back rounded vowel [o̞] or [ɔ̝] (normally written ⟨o⟩ as if it were close-mid)
As here, other back vowels can be transcribed with diacritics of relative articulation applied to letters for neighboring vowels, such as ⟨u̞⟩, ⟨o̝⟩ or ⟨ʊ̟⟩ for a near-close back rounded vowel.
