Elongation is so important tool in world of controling stuttering, it kills the difficult letters, you can elongate with 3 second or exaggerate and stretch the letter 5 seconds, its aim is to kill the fear of the difficult letter that we used to avoid in the past, and also killed his difficulty pronouncing. It does not have any negative effects. Do not rely on it alone, as there are stutterers who like elongation more than hitting the first letter because it is easy and does not need to resist the pressure of time when you use it. Therefore, my advice is to use all the four techniques, but focus on hitting the first letter and elongation, because they are the two techniques that show our true personality (we are people who stutter). ​ **Exhaling remaining air** is so important, we want to get the word flowing with air. If we leave air in the chest and take another air above the previous air, contractions will occur at the level of the diaphragm that cause us to stutter.Therefore, it is important to make sure that our chest is empty of air, then we take full breath into the chest and say the word or sentence directly without leaving a gap between the inhalation and exhalation (the perfect timing) (because this gap causes stuttering).And when saying the phrase consisting of 5 letters, no more, we devour the remaining air directly (return to the standby position) *Speech is air, so if we control the breath, we control speech* At the beginning of the journey towards controlling stuttering, it is important for the trainee not to exceed 5 words in the breath (try as much as possible).Because he will fall into problems such as wording problems before speaking and the problems of not respecting the resistance of time pressure, stuttering in the midst of a long sentence and more problems...Therefore, it is important for him to maintain a certain pattern, such as formulating a simple sentence, then saying it without stuttering (with techniques), then resting for 3 seconds, in which he formulates a new sentence and says it, and so on.With time, his wording will become strong and he will be able to speak and formulate a large number of sentences at the same time and say them without stopping.
