At what age do girls start to change their voice?

When women enter puberty, they are already 12-14 years old. This is the puberty of women and also the period of voice change. Many girls have already started to change their voices at this time. Some girls suddenly find that their voices seem different from before, and their speech seems to have changed a lot. Many people are not used to this phenomenon and always feel weird. In fact, it is normal. Everyone has to go through this change. So at what age does the voice change period of girls begin?

A child's voice change period is a critical period for the development of his or her voice. Generally speaking, how a child's voice develops during this period determines the quality of his or her voice throughout his or her life. To understand whether a child has entered the voice change period, one must look at age, second, gender (boys are mostly between 12 and 14 years old, girls mostly start at 12 years old), and third, the voice, which is the key point. If a child is at the age of voice change, his voice is hoarse when speaking, his voice cannot go up when singing, and a check of the vocal cords reveals congestion, this means that the child has entered the voice change period.

From the perspective of the physiological structure of the human larynx, there is not much difference between men and women before they reach maturity at the age of fifteen or sixteen, so there is not much difference in the voices of men and women at this time; when they reach maturity, the physiological morphology of the larynx of men and women becomes significantly different. The male larynx gradually becomes wider, the vocal cords become longer, the Adam's apple becomes more prominent, and the voice gradually becomes heavier and deeper. During this period, women's larynx changes are not so obvious, so the voice does not change much.

During the voice change period, boys' voices are usually about 8 degrees lower than before the voice change, while girls' voices are about 3 degrees lower. During this period, children may also experience symptoms such as hoarseness, dry throat, itchy throat, and foreign body sensation in the throat. Most children enter the voice change period around the age of 15. Girls usually start their voice change period one year earlier than boys. The voice change period lasts an average of one year, with the shortest being three to six months and the longest lasting two to three years. In addition, the length of the voice change period is also related to geography. Children in the south have a shorter voice change period, while children in the north have a longer voice change period.

The voice change period can be roughly divided into three stages: the voice does not change much in the early stage, and the voice is still a child's voice when speaking and singing, but sometimes you may feel that you have lost control of your voice, the voice becomes uncontrollable, it is difficult to produce high notes, the voice cannot be sustained, and sometimes the singing is out of tune or strange sounds appear; in the middle stage, the voice changes more obviously, the speaking tone becomes lower and rougher, and although the voice still has a child's voice, the child's voice component is getting less and less, and the adult voice component is gradually increasing; in the late stage, the voice has completely become an adult's voice, but there is still a period of time when the voice is unstable and difficult to control. Voice change is a necessary stage in human growth and development. It is a normal physiological phenomenon and there is no need to worry.

In order to help children get through this period smoothly, parents should pay attention to the following points:

1. Guide children to learn about the physiological and health knowledge of puberty, and let them understand the changes in voice and a series of physical changes before and after puberty.

2. Keep children mentally and emotionally stable. Studies have shown that emotional stress often causes vocal cord incomplete closure, edema, polyps and other pathological conditions. Therefore, making children feel happy is important for them to safely go through the voice change period.

3. Have adequate nutrition. In clinical practice, we have found that many young people with rough voices have a height that is extremely disproportionate to their age and are physically weak. After investigation, it turned out to be caused by malnutrition during the voice change period. Therefore, during the voice change period, you must eat more meat, eggs, dairy products, and fresh vegetables and fruits. Don't eat spicy or fried foods, and don't smoke or drink.

4. Get enough sleep. This is an important measure to protect your throat. Lack of sleep can lead to impaired blood supply to the brain, disrupt higher nervous activity, and prevent the cerebral cortex nerve cells from effectively regulating and controlling the laryngeal muscles. If waste products such as carbonic acid and lactic acid in the laryngeal muscles are not discharged in time, it will cause vocal cord spasm. In addition, sleep can give the brain and larynx a rest. Therefore, children in the voice change period should have a regular schedule and it is best to get enough sleep for 9 hours a day.

5. Educate your children to control their voice use. Loud arguing, yelling, and singing loudly are most likely to damage the vocal cords, so children should try to avoid them.

6. Ask a laryngologist to check your child’s throat regularly and correct any bad tendencies in a timely manner.

Girls must remember to protect their throats well during the voice change period. Don't underestimate the voice change period, as it will affect your whole life. If you speak loudly or often have hoarseness during the voice change period, then your voice will be like this in the future. So you must pay attention during the voice change period, avoid speaking loudly, eat more light and nutritious food, reduce stimulation, which will greatly protect your throat.
