Many men are distressed by their “girly” speaking voice, which not only affects their normal life, but also makes them feel inferior psychologically. In fact, “sissy” is a kind of functional dysphonia, which has a normal vocal cord mechanism in terms of anatomy or function, but is induced by excessive misuse and abuse of voice or incorrect laryngeal complementary action. Unlike other voice conditions, the vocal cords of boys who speak “girlishly” usually do not have a problem in themselves, but rather the way they are used. Usually, the problem is that after puberty, the boy’s voice changes suddenly, and he will deliberately make high notes to keep his voice from getting too low, and over time, this voice condition becomes a habit, so he will feel that he is closer to women, or he will have aversion to growing up and becoming an adult. Functional vocal disorders are usually divided into 6 types: 1. transformational aphonia; 2. habitual hoarseness; 3. inappropriate falsetto; 4. voice abuse, useless syndrome; 5. post-surgical dysphonia; 6. recurrent aphonia. Examination report of patients with functional dysphonia Normally, the voice frequency is 100-150 HZ for men and 200-250 HZ for women, and the data in the report shows that the patient’s voice frequency is 244.66 HZ. This shows that the voice frequency of patients with functional dysphonia is very high, which is why such patients speak “motherf This is the reason why these patients speak “girlishly”. Our behavior is done through the brain, which gives instructions to the relevant organs. Boys who speak “girlishly” have a problem with the brain’s communication of instructions and have unconsciously formed a habit. Most of them are triggered by mental problems. This functional vocal disorder, although not a direct problem of the vocal cords, can be “corrected” by injecting drugs. This correction can be done very quickly and can be adjusted in a few months if the symptoms are not very severe. The principle of injection is to artificially reduce the pitch of the external laryngeal muscles, which is related to the increase of the pitch, and then to restore the correct pronunciation habit by correcting the pronunciation pattern through electromyography. This method can shorten the treatment period and restore the normal voice in the shortest possible time.
