INTRODUCTION

Every sound belongs to one or other of two main classes known as vowels and consonants. Vowels are classified by lack of obstruction to the air stream, defused muscular tension, weak air stream. Consonantarticulatory obstruction to the air steam, muscular tension concentrated in the place of obstruction, strong air stream. The particular quality of a consonants depend on the work of the vocal cords, the position of the soft palate and the kind of noise that results when the tongue or the lips obstruct the air passage. An articulatory obstruction may be complete (is formed when the organs of speech come in contact with each other and the air passage through the mouth is blocked) or incomplete (an articulatory organ is held close to a point of articulation without blocking the air passage).

Classification of English consonants according to the manner of articulation. Mistakes typical of Russian learners of English and way of correcting them. The manner of articulation of consonants is determined by the type of obstruction. The obstructions may be complete, in-complete and momentary. When the obstruction is complete the organs of speech are in contact and the air stream meets a clo-sure in the mouth or nasal cavities as in the production of the English [p, b, t, d, k, g, tf, dj, m , n, n] .
