Boys' voices get deeper during puberty because of the growth of the larynx and lengthening of the vocal cords. This process is driven by increased levels of testosterone. As the vocal cords grow larger and thicker, they vibrate at a lower frequency, resulting in a deeper voice. This change usually occurs between the ages of 12 and 16 but can vary for each individual.
