Vowel
Definition:
(n.) A vocal, or sometimes a whispered, sound modified by resonance in the oral passage, the peculiar resonance in each case giving to each several vowel its distinctive character or quality as a sound of speech; -- distinguished from a consonant in that the latter, whether made with or without vocality, derives its character in every case from some kind of obstructive action by the mouth organs. Also, a letter or character which represents such a sound. See Guide to Pronunciation, // 5, 146-149.
(a.) Of or pertaining to a vowel; vocal.
Example Sentences:

(3) In addition, they were tested with dichotic listening for correct reports of consonant-vowel syllables.
(4) Test items in each of the 4 groups therefore contained different amounts of information regarding the nature of the following vowel, due to coarticulatory influences of the vowel on the preceding consonants.
(5) Coarticulatory effects of the vowel on the aperiodic portion were found to (1) occur early in the aperiodic portion, (2) vary with consonant and vowel, and (3) vary with vowel feature.
