Close-mid back rounded vowel
From MedBib.com - Medicine & Nature
Where symbols appear in pairs, the one to the right
represents a rounded vowel.
The close-mid 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 o, and the equivalent X-SAMPA symbol is o.
Features
- Its vowel height is close-mid, which means the tongue is positioned halfway between close vowel and a mid 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.
- Its roundedness is exolabial, which means that the lips are pursed and protrude, with the inner surfaces exposed.
Occurrence
Mid back rounded vowel
Many languages, such as Spanish and Japanese, have a mid back rounded vowel, which to speakers is clearly distinct from both the close-mid and open-mid vowels. However, since no language is known to distinguish all three, there is no separate IPA symbol for the mid vowel, and [o] is generally used. If precision is desired, the lowering diacritic may be used: [o̞].
Note that just because a language has only one non-close, non-open back vowel, that doesn't mean it's a cardinal mid vowel. The Sulawesian language Tukang Besi, for example, has a close-mid [o], whereas the Moluccan language Taba has an open-mid [ɔ]; in neither language does this contrast with another open/close-mid vowel.
Occurrence
In the following transcriptions, the lowering diacritic has been omitted for the sake of simplicity.
