A consonant is a speech sound that's not a vowel. The sound of a consonant is produced by a partial or complete obstruction of the air stream by a constriction of the speech organs. In writing, a consonant is any letter of the alphabet except a, e, i, o, u, and sometimes y.
Stop consonant. In phonetics, a stop, also known as a plosive or oral occlusive, is a consonant in which the vocal tract is blocked so that all airflow ceases. The occlusion may be made with the tongue blade ([t], [d]) or body ([k], [É¡]), lips ([p], [b]), or glottis ([Ê]).
