vowel
Definition -
(1) A spoken sound in which the vocal tract is opened so that air pressure doesn't build up above the glottis, e.g. the [ei] in the word bait (pronounced /beit/). This is in contrast to consonants where the vocal tract is constricted.
(2) The written symbols used to indicate English vowel sounds (e.g. a, e, i, o, u, and sometimes y).

Quotation -
"A vowel may be defined as voice (voiced breath) modified by some definite configuration of the super-glottal passages, but without audible friction (which would make it into a consonant)."
