Open Vowel

An open vowel is defined as a vowel sound in which the tongue is positioned as far as possible from the roof of the mouth. Open vowels are sometimes also called low vowels in reference to the low position of the tongue. The open vowels identified in the International Phonetic Alphabet are:

  • open front unrounded vowel
  • open front rounded vowel
  • open central unrounded vowel
  • open back unrounded vowel
  • open back rounded vowel

In the context of the phonology of any particular language, a low vowel can be any vowel that is more open than a mid vowel. That is, open-mid vowels, near-open vowels, and open vowels can all be considered low vowels.

Open vowels are used in nearly all spoken languages (one exception is Arapaho).

Famous quotes containing the words open and/or vowel:

    I perceive I have not really understood any thing, not a single
    object, and that no man ever can,
    Nature here in sight of the sea taking advantage of me to dart upon me and sting me,
    Because I have dared to open my mouth to sing at all.
    Walt Whitman (1819–1892)

    Brute animals have the vowel sounds; man only can utter consonants.
    Samuel Taylor Coleridge (1772–1834)
