|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 ⟨ʉ⟩, and the equivalent X-SAMPA symbol is
}. Both the symbol and the sound are commonly referred to as "barred u".
In most languages this rounded vowel is pronounced with protruded lips (endolabial). However, in a few cases the lips are compressed (exolabial).
There is also a near-close central rounded vowel in some languages.
The close central protruded vowel is typically transcribed in IPA simply as ⟨ʉ⟩, 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 ⟨ʉ̫⟩ for the close central protruded vowel. Another possible transcription is ⟨ʉʷ⟩ or ⟨ɨʷ⟩ (a close central vowel modified by endolabialization), but this could be misread as a diphthong.
Paired vowels are: unrounded • rounded
Note: 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 is no official diacritic for compression in the IPA, the centering diacritic is used with the front rounded vowel [y], which is normally compressed. Other possible transcriptions are ⟨ɨ͡β̞⟩ (simultaneous [ɨ] and labial compression) and ⟨ɨᵝ⟩ ([ɨ] modified with labial compression).
This vowel is typically transcribed in IPA with ⟨ʉ⟩. It occurs in some dialects of Swedish, but see also close front compressed vowel. The close back vowels of Norwegian and Swedish are also compressed. See close back compressed vowel. Medumba has a compressed central vowel [ɨᵝ] where the corners of the mouth are not drawn together.
