How old does a boy's voice start to change

Boys generally begin to change their voice at 12-14 years of age, but the exact age varies.

As boys enter puberty, their bodies undergo a series of changes, including the appearance of sexual characteristics and voice changes. During this stage, the throat gradually develops and the vocal cords become longer and thicker, resulting in a lower voice.

During puberty, the secretion of androgens increases, which plays an important role in the development of the throat. These hormones promote changes in the structure of the throat, causing significant changes in voice.

Although voice changes generally begin at 12-14 years of age, the exact timing may vary for each boy. Some may begin earlier, around 11 years of age; others may delay until 15 years or later. This individual variation is influenced by many factors, including genetics, nutritional status, and living environment.
