Wikipedia / Close central rounded vowel
The close central rounded vowel, or high central 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 . The sound is also commonly referred to by the name of its symbol, "barred u".
The close central rounded vowel is the vocalic equivalent of the rare labialized post-palatal approximant .
In most languages this rounded vowel is pronounced with protruded lips (endolabial). However, in a few cases the lips are compressed (exolabial).
Close central protruded vowel
The close central protruded vowel is typically transcribed in IPA simply as , and that is the convention used in this article. As there is no dedicated diacritic for protrusion in the IPA, symbol for the close central rounded vowel with an old diacritic for labialization, , can be used as an ad hoc symbol for the close central protruded vowel. Another possible transcription is or (a close central vowel modified by endolabialization), but this could be misread as a diphthong.
Features
Occurrence
Because central rounded vowels are assumed to have protrusion, and few descriptions cover the distinction, some of the following may actually have compression.

Close central compressed vowel
As there are no diacritics in the IPA to distinguish protruded and compressed rounding, an old diacritic for labialization, (the opposite of ), will be used here as an ad hoc symbol for compressed central vowels. It was only added to Unicode in 2025, however, and it may take some time for font support to catch up. Another attested transcription is ( modified with labial compression), though this may imply that the vowel is a diphthong (as indeed it is in Swedish).
The central-vowel stroke of may also be used with the front compressed vowel to create the ad hoc symbol , or the diacritic for centralization to create .
