The near-close central unrounded vowel, or near-high central unrounded vowel, is a type of vowel sound, used in some spoken languages. The International Phonetic Alphabet can represent this sound in a number of ways (see the box on the right), but the most common symbols are 〈ɪ̈〉 (centralized[ɪ]) and 〈ɨ̞〉 (lowered[ɨ]). In many British dictionaries, this vowel has been transcribed 〈ɪ〉, which captures its height; in the American tradition it is more often 〈ɨ〉, which captures its centrality, or 〈ᵻ〉, which captures both. The third edition of the OED adopted 〈ᵻ〉 as a conflation of 〈ɪ〉 and 〈ɨ〉 to represent either [ɪ̈] or a vowel that varies between [ɪ] and [ə].
The IPA prefers terms "close" and "open" for vowels, and the name of the article follows this. However, a large number of linguists, perhaps a majority in the USA, prefer the terms "high" and "low".
