Puberphonia treatment idea

How  I got the idea of pharyngeal resonance manipulation training for treating puberphonia in one to three days ?.
  Teachers were more likely to perceive that a voice problem would adversely affect their future career options, had done so in the past, and was limiting their current job performance.I used to teach teachers pharyngeal resonance manipulation training with "breath of fire" training.100% of teachers had never missed any days of work due to a voice problem. These findings suggest that teaching is a high-risk occupation for voice disorders and that this health problem may have significant work-related and economic effects.Similarly puberphonia: is it a high risk problem ?.
