The classification of Speech sounds The organs of speech are capable of making many different kinds of speech sounds. From the practical standpoint, speech sounds are generally divided into Vowels and Consonants
a Vowels are sounds produced without obstruction of the air stream in the mouth in producing them there is vibration of the vocal cords, so all vowels are voiced In English there are twenty vowels in all a Consonants are sounds produced by some form of obstruction of the air passage and be either voiced or voiceless There are twenty-eight consonants in English

Vowels General Remarks on the vowels The English vowels are divided into two large groups Monophthongs(pure vowels) Diphthongs
Vowels General Remarks on the Vowels The English vowels are divided into two large groups: ◼ Monophthongs (pure vowels) ◼ Diphthongs
Monophthongs There are twelve monophthongs. They may be classified according to the following principles 1The height of the raised part of the tongue: we distinguish open vowels, half-open vowels, half-close vowels and close vowels 2)The part of the tongue raised we distinguish front, back and central vowels 3The length of the vowel: we distinguish long vowels and short ones 4The position (or shape) of the lips: we distinguish rounded vowels and unrounded ones 5The degree of tenseness: we distinguish tense vowels and lax vowels
