A 'central vowel' is a type of
vowel sound used in some spoken
languages. The defining characteristic of a central vowel is that the tongue is positioned halfway between a
front vowel and a
back vowel. The central vowels identified by the
International Phonetic Alphabet are:
★
close central unrounded vowel
★
close central rounded vowel
★
close-mid central unrounded vowel
★
close-mid central rounded vowel
★
mid central vowel
★
open-mid central unrounded vowel
★
open-mid central rounded vowel
★
near-open central vowel
★
open central unrounded vowel (unofficial but most frequent usage)
Occasionally, the ''ad hoc'' symbols for near-close central vowels will be seen.
