Vowels
There are forty-four sound segments in English comprising twenty vowels and twenty-four consonants and in English Alphabets there are twenty six letters five are vowels while twenty one are consonants.
There are five letters, a, e, i, o, u which are letters broken into twenty sounds segments. The production of these takes place as the air stream flows from the lings to the mouth without any obstruction, when the speech sound is produced the mouth is open and the tongue does not touch the top of the mouth and teeth, when a vowel is produced there is no obstruction of the air stream. For example if your produce /e/ you will notice that air flows out freely from the lungs. Although the long is raised when the vowel is produced, it does not make any contact with any other articulator as to obstruct the free flow of the air stream. Unlike the consonant when produced there is always some kind of interruption of the air stream from the lungs e.g. /m/ when produced, you notice the flow of air is obstructed.
