Mutation or "breaking" of the voice in adolescents is due to serious changes in hormonal levels. Boys are primarily susceptible to voice breakage, but in some cases, girls also have certain problems with their voice during this period.
How does the voice break?
Voice mutation occurs during puberty. Testosterone enters the boy's blood in large quantities, this sex hormone causes the glottis to expand, as a result, the voice acquires a hoarseness and a lower frequency characteristic of men.
Before the start of withdrawal, the structure of the vocal apparatus in girls and boys is identical. Until a certain age, it is impossible to determine the gender of a child by his voice. From about ten years old, boys experience their first voice changes, they begin to speak in a lower tone than girls. This is due to the fact that in boys the ligaments and glottis grow a little faster; such changes are associated with the physiological characteristics of growing up. At the age of ten to twelve, the boy's glottis is on average only one and a half millimeters larger than the girl's glottis, and the difference in the tonality of the sound is already very noticeable.
Age-related voice mutations are normal. They begin at the same time as the hair growth of the pubis, armpits and the first emission. Most often, in parallel with the breaking of the voice, hair begins to grow on the face.
Voice changes can occur between eleven and eighteen years of age. A later mutation most often indicates certain problems with the hormonal background and male health of the adolescent. Breaking the voice usually takes no more than two months; during this time period, the voice completely changes the tonality and timbre, which then remain unchanged throughout life. Only burns, injuries to the larynx, or abuse of bad habits can change them.
Changes in progress
In the process of breaking, the vocal cords thicken significantly, and the glottis expands. In addition, boys undergo very noticeable anatomical changes in the skeleton of the larynx. The thyroid and other laryngeal cartilages rapidly increase in size, with the front edge of the larynx protruding forward, forming the Adam's apple.
In order for the breaking of the voice to go away faster, the vocal cords need to be loaded as little as possible, since due to overstrain, nodules can appear on the vocal cords, which cause very noticeable hoarseness. If the load on the speech apparatus decreases, some of the nodules can dissolve on their own, but sometimes you have to resort to surgical intervention.
It should be borne in mind that a variety of colds can tighten the voice mutation. However, reddening of the throat in a teenager during the period of "breaking" of the voice may not be caused by a respiratory infection, but directly by the growth of the larynx, since active growth increases blood circulation in this area.
