You have 2 queries 1. Why all stutter in a similar Situation 2. How stuttering is different from person to person Let me try my best to answer in simple words but this is a bit complicated for explanation Answer 1 : all stuttering people stutter in similar situations is not true. To understand this, you should define the concept "situation" here. In general, the situation is a condition or environment or state happening. If all stuttering people from the entire world participate in presentation/stage speaking competition then chances are all will stutter BUT CONDITION OR STATE WILL BE DIFFERENT FOR EACH PERSON Examples - few will stutter at the beginning & few in the middle or combination. Few will stutter due to first time experience & few will stutter due to anxiety or combination. You need to identify the state/condition behind stuttering in perticular situation. If you focus only on stuttering, then a so-called fluent person also stutters sometimes under extreme pressure. Considering all stutter in similar situations is not clarity. You need to define sub situations inside the main situation & there is a difference. Handling those macro situations inside the situation is a real game changer for stuttering people. I know it is a complicated topic, but in conclusion to this answer - identifying real root causes behind stuttering in those situations makes your stuttering different from others. Answer 2 - stuttering is an output or representation of your current state of mind +breathing+other factors. People who speak fluently are also an output of their current state of mind & other factors. Even I can claim this - the person who Stutter has 2 personalities inside it & it changes based on situations like sometimes Stutter & sometimes fluent. Stuttering is just a result & if you observe other people who Stutter then everyone stutters differently. Best example to understand this is - take 10 people who Stutter & ask them to introduce themselves using same format like - name, age, address, profession, story behind Stuttering. Everyone will stutter differently. IF YOU JUST SEE STUTTERING THEN YOU DON'T FIND ANY DIFFERENCE BUT WHEN YOU CHECK THEIR STATE, WORDS, SPEED, STATE OF MIND, ETC You WILL SEE DIFFERENCE. SO TECHNIQUE WHICH WORKS ON SOMEONE DOESNT MEAN IT IS A UNIVERSAL SOLUTION. in conclusion for this answer - understanding the trigger behind stuttering can easily differentiate stuttering among others. I know it is complicated to understand. But once you understand this, you will find a solution. Hope I tried my best to answer your questions
