The voice of teenage boy becomes deeper due to growth of larynx
Explanation:
Before a boy reaches puberty, his larynx is pretty small and his vocal cords are kind of small and thin. That's why his voice is higher than an adult's. But as he goes through puberty, the larynx gets bigger and the vocal cords lengthen and thicken, so his voice gets deeper.
Several changes that occur in teenage boys cause their voices to deepen. The cartilage in the voice box is very sensitive to testosterone. As this cartilage receives testosterone, sent from the testicles, it grows larger and thicker. At the same time, the vocal cords grow 60% longer and become thicker.
