Over the years, I have attended to quite a few people with various voice disorders, speaking and singing.
Interestingly enough, in the case of stuttering, in particular, singing could actually help to cure, or significantly minimize, this very annoying and unpleasant for the person and for the listener, disorder.
In fact, watching the recent American Idol episodes, you could see a young, quite good-looking, contestant singing perfectly, but stumbling upon (stuttering), each and every word.
It is quite a phenomenon, people might think.
In reality, it is not.
The Vocal Science ™ method, which I discovered, suggests that the speaking and singing sound should be placed and should come out off of the upper vocal chambers, (facial cavities) and not the vocal cords, at least, after the initial first syllable of the word is initiated.
The contestant in American Idol does it intuitively and experientially, but not knowing the science behind it. Therefore, it works for him when he is singing, but not when he is speaking, as for speaking, he is using the regular parts of his vocal box, ie, vocal cords, larynx, etc.
Vocal Science ™ method promotes the mechanism, which consists of 3 simultaneously working, breathing components and the facial muscles, which are working in full conjunction and coordination with the abdominal muscles, (for breathing support), so then the vocal box itself is engaged only in the minimal capacity.
So, if using the same method, the person with light stutter will apply the same mechanism components, which ultimately allow the voice to work in it’s fullest capacity possible and without excessive use of the lower vocal anatomy, the stutter will be greatly minimized and, could be even completely eliminated.
