Voice changes during puberty are caused by hormones making your vocal cords grow, here’s what’s happening and what to expect.
Hormones Trigger Growth
Testosterone (which everyone has in varying amounts) causes your larynx (voice box) to grow larger and your vocal cords to get longer and thicker.
Thicker Cords Mean Deeper Voice
Thicker, longer vocal cords vibrate more slowly, creating deeper sounds. That’s why your voice is getting lower or richer than it was as a child.
The Change Is Gradual
Voice change typically takes 2-3 years. It doesn’t happen overnight, your voice deepens in stages as your larynx continues growing.
Everyone’s Timeline Differs
Some people’s voices drop dramatically, others change more subtly. Some change early, others late in puberty. All patterns are normal.
The Adam’s Apple Grows Too
The visible bump on your throat (laryngeal prominence) becomes more noticeable as your larynx grows. This is a normal part of development.
Your Voice Will Settle
Once growth completes, your voice stabilizes. The adult voice you end up with will be your voice, cracking and uncertainty are just the transition phase.
Amount of Change Varies
Some people’s voices drop significantly, others less so. How much your voice changes is mostly genetic, everyone’s final voice is unique.
It’s a Sign of Healthy Development
Voice change is one marker that puberty is progressing normally. It’s not something to be embarrassed about, it’s your body maturing.
