The disease or habit which we term as stammering is in fact a habit of speaking with pauses. This is not a physical disorder by birth but because of shortened breath in the childhood due to some of the following reasons:

Due to short breath, a person starts speaking with pauses and interruptions (as speech develops from breath). He does not want to speak with pauses. But since he is not aware of the actual cause of these pauses, he tries to speak out more words in that short breath. This results in the abnormal increase in the speed of speech. Speaking more in short breath causes stammering and it becomes a habit. This is “Stammering”

Psychology:    If a person regularly stammers from childhood, it casts an impression in his mind also. While speaking, a thought occurs in his mind that he speaks with pauses. This fear further aggravates his problem. This is  “Psychology”.

Some persons give more attention to this problem. Some words, which are frequently used, cause more problems to them due to high speed. They consider these words as problematic.

A stammerer will always try to speak fluently. While speaking, he has two options either to speak out these problematic words with pauses or substitute these with some other words. For example, if a person has selected “P” as a problematic alphabet and he is to speak out “P-P-P-Pani” (Water), he will substitute it with “Jal” (Water). This act increases the psychology in his mind and so the depth of stammering. He keeps on stammering through out his life.

Stammering is of one kind but its depth varies from person to person. A person, who gives more thought and attention to this problem, will have more depth, whereas, a person who does not care much about the problem will have less depth.
