Dear R34skyline,

Eventually, yes! At puberty, the hormone testosterone causes a guy's larynx, or voice box, to increase in size. The larynx often grows bigger so rapidly that it causes a guy's voice to "break," crack, and squeak. As the vocal cords in the larynx get thicker and longer, the tone of the voice deepens. When the larynx finishes growing, a guy will end up with a voice that's consistently lower than it used to be. The same thing happens as girls mature into women, but it usually doesn't happen as rapidly for them — or as much.

Remember, puberty doesn't happen all at once — it happens in stages. So a girl or boy may show some signs of puberty at an early age (like breasts beginning to grow or a voice that's starting to crack), but may not show other signs of puberty until she or he is much older (like getting a period or growing facial hair). Believe it or not, it can take up to 20 years of age for all changes to take place.

Hope this information helps!

Take care,
