1)The Height of the Tongue:
This parameter gives us the categories of close, half close half open and open vowel sounds, Tongue position is described using two criteria: the height (how high is the tongue)_ and the part of the tongue is involved in the production of sound.
2)Position of lip
The parameter gives us the categories of spread and rounded vowel sounds.
3)General area of the mouth
This parameter gives us the categories of spread and rounded vowel sound
A)Description of Monothongs (Single Vowel sounds)
In the description of pure vowel sound al the areas of mouth namely front central and back are used. here we shall describe pure vowel sounds in three of mouth.
1)Front Vowel Sound
in the front area English has four vowel sounds. All are made with spread lips.
i. Close Front Spread Vowel:
First of all there close frond spread vowel. It is found in words such as "beat" or "feast". This word "feast" is translated as / fi:st /
ii. Lowered and centralized close spread vowel:
this is the more open and more central close front vowel .it id found in such words bit which is translates as /bIt/
iii. Mid front Spread vowel:
English has no vowel as precisely either the half close and the half open position, but one mid way between the two. This is usually described mid frond spread vowel. it is found in words such as bet, lest etc. it is symbolized by /e/ which is the international phonetic alphabet symbol for a half close front spread vowel.
iv. Open Front Spread vowel:

iv. Open back rounded vowel:
Open back rounded vowel is one of the two vowel sounds, which are found in the open back area of mouth. This open back rounded vowel is not completely open but somewhere between half and open.it is found like hot and got.
