How long does it take for a boy to change his voice?

Puberty is an important period for boys and girls, because during this period, their bodies will undergo major changes, and their minds will gradually mature. The biggest change for girls is the gradual development of their breasts, while the biggest change for boys is the gradual growth of their Adam's apples and the gradual change of their voices. Every boy has to go through a period of voice change, and the voices of boys who have gone through a voice change will become more mature. How long does the voice change period for boys generally last?

First, the time of voice change

Generally speaking, boys begin to enter the voice change period at the age of 13, and have fully entered the voice change period at the age of 15. At this time, the voice of adolescent boys is relatively low and hoarse, changing the previous childish voice characteristics. Boys after the age of 19 have prominent Adam's apples and their voices become coarser. During the voice change period, the physiological changes of adolescent boys vary. Some boys change their voices so strongly that their voices become slightly coarse with cracks and hoarseness, and they make false voices - "broken throats". Of course, these are only temporary and normal physiological phenomena. Fathers and adolescent boys don't have to worry. The length of the voice change period varies from person to person, and the shortest is 4 to 6 months, and the longest can be up to about a year. The length of the voice change period is also closely related to geographical location. The length of the voice change period for boys in the south is relatively shorter, at about 4.7 months, while the length of the voice change period for boys in the north is longer, at about 6 to 12 months.

Second, the role of vocal cords

The quality of voice is determined by the vocal cords. The vocal cords are a pair of elastic mucosal folds located on both sides of the laryngeal cavity, and their length, thickness and thickness vary from person to person. The vocal cords are an important factor in determining the timbre. When boys enter the puberty period, the main manifestations are hoarseness, local congestion and edema of the larynx, and the pitch and timbre will also gradually change. The reason why adult men have rough and low voices, and the volume is wide and thick, is because the length, width and thickness of their vocal cords are greater than those of minors. During the puberty period, if the boy's throat is exposed to adverse external stimuli, it is easy to cause permanent damage to the vocal cords, which will greatly affect the voice in adulthood.

In short, human voice is mainly produced by the vibration of the vocal cords, which is the organ of voice production in the body. The vibration of the vocal cords is related to the development of the larynx. The reason why adolescent boys have rumbling voice is that the larynx begins to develop rapidly in front and back, up and down, and left and right. In particular, the forward protrusion of the thyroid cartilage makes the Adam's apple thicker and larger, and then the voice changes accordingly. The voice change period is just an episode of puberty. Both fathers and adolescent boys do not need to worry. It is just a short process.
