Mid back rounded vowel
The mid back rounded vowel is a type of vowel sound, used in some spoken languages. While there is no dedicated symbol in the International Phonetic Alphabet that represents the exact mid back rounded vowel between close-mid and open-mid , it is normally written . If precision is desired, diacritics may be used, such as or , the former being more common. There was an alternative IPA symbol for this sound, ⟨ꭥ⟩. A non-IPA letter is also found. Just because a language has only one non-close non-open back vowel, it still may not be  a true-mid vowel. There is a language in Sulawesi, Indonesia, with a close-mid , Tukang Besi. Another language in Indonesia, in the Maluku Islands, has an open-mid , Taba. In both languages, there is no contrast with another mid (true-mid or close-mid) vowel. Kensiu, in Malaysia and Thailand, is highly unusual in that it contrasts true-mid vowels with close-mid and open-mid vowels without any difference in other parameters, such as backness or roundedness.
