Wow you seem very knowledgable in stuttering so I guess you may be an SLP or neurologist? May I ask what is 'smooth speech technique"? The technique that I need to prolongate my pronouncing instead of 'bursting out' letters/words? Actually if you would like to check my last posts out, you can see I am achieving a speech therapy conducted by an SLP named Zhen Chen and he is indeed introducing me this technique.
