My goal is to speak fluently like a person who does not stutter. I already said that language exercises can be good for knowing how to breathe, modulate the voice, the volume, but that has nothing to do with what happens in the brain. If the word does not come out of the mouth it is because there is a blockage, and I have already said that everything happens through what we have already heard, broca's area, basal ganglia, dopamine receptors, etc.
