Unit 3. The Classification of English Consonant Phonemes
A consonant
is a sound produced with an obstruction to the air stream. English
consonants are usually classified according to the following principles:
I. According to the type of obstruction and the manner of the production of noise.
II. According to the active speech organ and the place of obstruction.
III. According to the work of the vocal cords and the force of articulation.
IV. According to the position of the soft palate.
According to the type of obstruction English consonants are divided into
occlusive
and
constrictive
.

articulating organs, the air – passage to the mouth cavity is blocked. Occlusive consonants
may be:

Plosive consonants are [p], [b], [t], [d], [k], [
