Why are male voices lower than female?
Male and female voices
Men's voices are generally deeper because the surge of testosterone released during puberty causes their vocal cords to elongate and thicken. Like the strings of a cello, thicker, longer vocal cords produce a deeper sound.
Why do boys have low voices?
At puberty, guys' bodies begin producing a lot of the hormone testosterone (pronounced: tes-TOSS-tuh-rone), which causes changes in several parts of the body, including the voice. For starters, a guy's larynx (pronounced: LAIR-inks), also known as the voice box, grows bigger.
Why do females have a higher voice than males?
The vocal cords' vibration makes sound, just like a strummed guitar does. And like guitar strings, smaller cords create a higher sound. Girls' vocal cords are usually shorter and thinner than most boys', which is why their voices sound higher. This difference in pitch is even more noticeable in grown-up men and women.

The Changing Larynx
As the body goes through puberty, the larynx grows larger and thicker. It happens in both boys and girls, but the change is more evident in boys. Girls' voices only deepen by a couple of tones and the change is barely noticeable. Boys' voices, however, start to get significantly deeper.
