What  is  in my voice? 

 The spectral analysis of announcers’  speech, performed  by scientists, demonstrated, that the most known of them have the whole  frequency range from 80 up to 2800 Hz, while the average person during conversation uses the range on  average  80 - 500 (maximum 1700) Hz.  The zone of the so-called high formant (from 2000 up to 2800 Hz) is seldom used, namely it reflects such characteristics of speech as confidence, expressiveness and persuasiveness. The more of these qualities are  in the person’s speech , the  higher waves by amplitude are present at this spectral region, the higher  the   mean value of high formant is. These data couldn’t but  interest us, in fact it was a question of  fine and informative technique, applied for identification of  voice of telephone blackmailers, hooligans, terrorists and even prominent politicians. And if  the picture of the voice, "decomposed" to frequencies, gives so much information on its owner, we couldn’t but   assume, that  the spectrum of the voice  of a stuttering person   will also have some characteristics. 

Indeed, the analysis of the stuttering people voices demonstrated a displacement of the speech spectrum (in comparison with not stuttering  people) into the low-frequency field - in the field of 0-10 Hz there are  overtones, "responsible" for occurrence of spasms and stumblings. It turns out, that stuttering provokes and strengthens stuttering. Therefore some experts also speak, that stuttering "can’t be treated".  

However if the person is learnt to speak without these low-frequency overtones, the inclination to spasms will disappear! You can obtain it, having reconstructed the speech spectrum through  all the scale of frequencies, mainly displacing it into the  field of high formant. It is noted, that stuttering stops and becomes impossible at the value of  high formant of the  voice more than 30 %. 

Is it much or  little? Judge: In speech of a stammering person this parameter is equal on  average to 2-7 %, of not stammering people  - it makes approximately 12-15 %, of professional announcers with well "trained" voices keep a high formant  in the range of 30-50 %.   The well-known announcer of the Soviet Union Jury Levitan had 60 % of his voice  spectrum in the field of high formant, and the well-known  Volga bass Feodor Shalyapin - 80 %! Here are the opportunities, which  are hidden in our speech organs! Hence, 30 %-boundary is a quite feasible task, though it   exceeds  in 2-2,5 times a parameter of the average person. It turns out, that a stammering patient for the rescue of his illness should improve the speech data in 6-10 times!!! 

There is a natural question - how  easy You can achieve it? It has appeared, that for achievement of the necessary level of high formant it is only necessary  to know  three small secrets,  which will be defined  in  the following section.
