Yes, girls absolutely have a voice box, which is medically known as the larynx. The larynx is an essential part of the human anatomy, present in everyone, regardless of gender. It plays a crucial role in breathing, preventing food from entering the windpipe, and most importantly, in producing sound, allowing us to speak, sing, and express ourselves vocally.
Understanding the Larynx
The larynx is a complex organ made of cartilage, muscles, and ligaments, located in the neck, at the top of the windpipe (trachea). Inside the larynx are two bands of muscle tissue known as vocal cords (or vocal folds). When air passes through the vocal cords during exhalation, they vibrate, creating the sounds we hear as speech and song.
Voice Changes During Puberty
While both boys and girls have a voice box, its development and the resulting vocal changes during puberty differ significantly, leading to common misconceptions.
During puberty, hormonal changes cause the larynx to grow larger and thicker in both boys and girls. However, the extent of this growth and its impact on vocal pitch are far more pronounced in males.
- For girls, the voice box does grow, and their vocal cords lengthen and thicken, which causes their voice to deepen slightly. This change is typically subtle, usually deepening by only a couple of tones, and is often barely noticeable to others.
- For boys, the larynx grows considerably larger, leading to a much more significant lengthening and thickening of the vocal cords. This results in a noticeable and often dramatic deepening of the voice, sometimes referred to as a "voice crack" or "voice break," as it transitions to a lower pitch. This growth is also why boys often develop a prominent Adam's apple, which is the cartilage of the larynx protruding from the neck.
The table below highlights the key differences in voice changes experienced by girls and boys during adolescence:
| Feature | Girls | Boys |
|---|---|---|
| Larynx (Voice Box) Growth | Yes, grows larger and thicker | Yes, grows larger and thicker, more significantly |
| Vocal Cord Changes | Lengthen and thicken | Lengthen and thicken considerably |
| Voice Deepening | Slight; typically a couple of tones | Significant; voice gets much deeper |
| Noticeability of Change | Barely noticeable | Very noticeable; often includes "voice cracks" |
| Adam's Apple Prominence | Typically not prominent or visible | Often becomes prominent and visible due to larynx growth |
The Role of Vocal Cords
The size and tension of the vocal cords within the larynx directly influence the pitch of a person's voice.
- Thicker, longer vocal cords tend to vibrate slower, producing lower-pitched sounds.
- Thinner, shorter vocal cords vibrate faster, producing higher-pitched sounds.
This fundamental principle explains why men generally have lower voices than women, as their vocal cords are typically longer and thicker after puberty.

In summary, the voice box is a universal component of human anatomy, present and functional in girls, boys, and all individuals. Its development during puberty simply manifests differently between sexes.
