How Puberty Affects the Voice

Your voice is produced when air passes through your throat and makes your vocal cords vibrate. Your vocal cords are two thin strips of tissue that stretch across your larynx, or voice box. The size and shape of your larynx and vocal cords determine the pitch and tone of your voice. The longer and thicker your vocal cords are, the lower your voice sounds.

The Role of the Larynx and Vocal Cords

Before puberty, boys and girls have similar-sized larynxes and vocal cords. They also have similar vocal pitches, which are usually high. However, during puberty, boys experience a rapid growth spurt in their larynxes and vocal cords. Their larynxes become larger and more prominent, which is why some boys develop an "Adam's apple". Their vocal cords also become longer and thicker, which lowers their voice pitch.

As your body adjusts to these changes, your voice may crack or break. This is because your vocal cords are still learning how to work with your new equipment. Sometimes they may stretch too tight or too loose, causing your voice to squeak or croak. This process usually lasts only a few months until your vocal cords settle into their new position.

The Role of Testosterone

What causes your larynx and vocal cords to grow so much during puberty? The main culprit is testosterone, a hormone that is responsible for many male characteristics. Testosterone is produced by your testicles and released into your bloodstream. It travels to different parts of your body, including your larynx and vocal cords, and stimulates their growth.

Testosterone also affects the quality or "color" of your voice, which is called timbre. Timbre is influenced by the shape and size of your vocal tract, which includes your nose, mouth, throat, and sinuses. As your larynx grows, your vocal tract becomes wider and longer, allowing your voice to resonate better. This gives your voice a richer and fuller sound.

The Role of Genetics and Environment

While testosterone plays a major role in voice changes during puberty, it is not the only factor. Your genes and your environment can also affect how your voice develops. For example, some boys may inherit a tendency to have a larger or smaller larynx, or to produce more or less testosterone. These factors can influence when and how much your voice changes.

Your environment can also affect your voice. For instance, if you are exposed to loud noises, smoke, dust, or allergens, you may irritate your vocal cords and cause them to swell or become inflamed. This can make your voice sound hoarse or raspy. If you have a cold, a sore throat, or an infection, you may also experience temporary voice changes. These conditions usually resolve on their own or with proper treatment.

When to Expect Voice Changes

Now that you know how puberty affects your voice, you may wonder when to expect these changes to happen. The answer is not so simple, because every boy is different. Voice changes can happen at different times and at different rates for different boys. However, there are some general guidelines that can help you estimate when and how long your voice will change.

The Tanner Stages

One way to predict when your voice will change is to look at the Tanner stages of puberty. The Tanner stages are a scale that describes the physical development of boys and girls during puberty. They range from stage 1 (pre-puberty) to stage 5 (full maturity). Your doctor can assess your Tanner stage by examining your genitals, pubic hair, and other body changes.

Voice changes usually happen when boys are between Tanner stages 3 and 4. At this point, you may notice that your testicles and penis have grown larger, your pubic hair has become thicker and darker, and your body has become more muscular. You may also experience growth spurts in height and weight.

The Age Range of Voice Changes

Another way to estimate when your voice will change is to look at the average age range for voice changes. Most boys start to experience voice changes between the ages of 12 and 13. The changes are mostly complete by the ages of 15 to 18. However, this is only an average, and some boys may start earlier or later than others.

The age at which you start to experience voice changes depends on several factors, such as genetics, nutrition, health, and ethnicity. Some boys may inherit a tendency to start puberty earlier or later than others. Some boys may have better nutrition or health conditions that support their growth. Some ethnic groups may have different patterns of puberty than others.

The Duration of Voice Changes

A final way to estimate how long your voice will change is to look at the average duration of voice changes. Most boys go through voice changes for about six months to two years. However, this is also an average, and some boys may go through them faster or slower than others.

The duration of your voice changes depends on how quickly or slowly your larynx and vocal cords grow and adjust. Some boys may have a sudden growth spurt in their larynx and vocal cords, which causes their voice to change quickly. Some boys may have a gradual growth spurt in their larynx and vocal cords, which causes their voice to change slowly.

Coping With Voice Changes

Voice changes during puberty can be challenging for many boys. You may feel embarrassed or self-conscious about your voice cracking or sounding different. You may worry that others will tease you or judge you for your voice. You may also feel frustrated or confused about how to deal with your voice changes.

The good news is that there are ways to cope with voice changes during puberty. Here are some tips for dealing with voice cracking, taking care of your voice, and embracing your new voice.
