Front vowel

A front vowel is a class of vowel sounds used in some spoken languages, its defining characteristic being that the highest point of the tongue is positioned as far forward as possible in the mouth without creating a constriction that would otherwise make it a consonant. Front vowels are sometimes also called bright vowels because they are perceived as sounding brighter than the back vowels.

Near-front vowels are essentially a type of front vowel; no language is known to contrast front and near-front vowels based on backness alone.

Rounded front vowels are typically centralized, that is, near-front in their articulation. This is one reason they are written to the right of unrounded front vowels in the IPA vowel chart.
