Languages may have a
mid central rounded vowel (a rounded ), 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 the symbol for the
close-mid central rounded vowel is generally used instead. If precision is desired, the lowering diacritic can be used, , or the
more rounded diacritic with the schwa symbol, , or the
raising diacritic with the
open-mid central rounded vowel symbol, , although it is rare to use such precision. Some of the vowels listed in the table below may phonetically be more front than typical central vowels, as
near-front vowels. If precision is required, this may instead be called a
mid near-front rounded vowel. For those which are more back than typical central vowels, see
mid near-back rounded vowel.
