Puberphonia

Puberphonia is the functional, habitual use of high-pitched voice post puberty after the vocal folds have reached typical adult size.

This condition is seen in males more often than in women.
Puberphonia is also more noticeable in men than women because men are expected to speak much lower than women, and less noticeable in women because women typically speak much higher than men.
Homoeopathy is the most popular holistic system of medicine able to cure permanently and in minimum dose itself as is seen in my experience.
