In phonetics, vowel roundedness refers to the amount of rounding in the lips during the articulation of a vowel. It is labialization of a vowel. When a rounded vowel is pronounced, the lips form a circular opening, and unrounded vowels are pronounced with the lips relaxed.
Why are back vowels rounded?
Rounding and protruding the lips lowers the frequencies of the acoustic resonances of the vocal tract to add to the lowering effect produced by the action of backing the body of the tongue. A rounded back vowel is therefore more clearly distinct from other vowels than an unrounded one (see Stevens 1972).
What are rounded back vowels?
