Consonants
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract. Examples are and pronounced with the lips; and pronounced with the front of the tongue; and pronounced with the back of the tongue; , pronounced in the throat; , and , pronounced by forcing air through a narrow channel (fricatives); and and , which have air flowing through the nose ( nasals). Contrasting with consonants are vowels. Since the number of speech sounds in the world's languages is much greater than the number of letters in any one alphabet, linguists have devised systems such as the International Phonetic Alphabet (IPA) to assign a unique and unambiguous symbol to each attested consonant. The English alphabet has fewer consonant letters than the English language has consonant sounds, so digraphs like , , , and are used to extend the alphabet, though some letters and digraphs represent more than one consonant.

Vowel
A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and stress. The word ''vowel'' comes from the Latin word , meaning "vocal" (i.e. relating to the voice). In English, the word ''vowel'' is commonly used to refer both to vowel sounds and to the written symbols that represent them (a, e, i, o, u, and sometimes y). Definition There are two complementary definitions of vowel, one phonetic and the other phonological. *In the phonetic definition, a vowel is a sound, such as the English "ah" or "oh" , produced with an open vocal tract; it is median (the air escapes along the middle of the tongue), oral (at least some of the airflow must escape through the mouth), frictionless and continuant ...
