Mr. Zhang is already a year old, but especially afraid to answer the phone. For no other reason, when he finished “Hello”, the other party will come back to a “Miss Hello, please help me find ……” Mr. Zhang was at a loss for words, and this situation has plagued Mr. Zhang for many years. He often envies the kind of baritone men, but also for their own pointed tone of voice feel inferior. This condition is often referred to as male voice female tone. The incidence of male voice with female tone is not high, but it seems to occur among our men if at all. What are the main causes? The voice of both men and women is high pitched during childhood, but after puberty, the pitch of the voice starts to drop, less for women and more for men. As adults, the pitch of men’s voices is significantly lower than women’s. However, some men’s laryngeal structure changes during the voice change period, but the memory of children’s high-pitched voices affects them implicitly, causing them to involuntarily raise the pitch of their voices when they open their mouths. This high pitch does not reach the high pitch of childhood, but falls right in the range of the adult female pitch, which sounds like female pronunciation. And the habit of pronunciation is very difficult to correct, just like hunchback, it needs hard practice to correct. In most cases, regular voice training can correct this habit, but in a few cases, we need to use injection therapy or surgery to achieve the goal. Except for surgery, voice training and injection therapy are the easiest and simplest ways. Finally, Mr. Zhang finally changed his voice to a masculine alto voice through hard training. Mr. Zhang was lucky to have someone to train him and the training was effective. However, some people need to use injectable drugs to achieve the training effect. There are also some people who cannot achieve their goal even after training. These people often have structural developmental problems of the vocal folds, such as short vocal folds and vocal fold grooves in males, and this is when surgery is needed.
