HAVE you ever thought about how interesting it is that you can instantly identify the voice of your favorite singer? What would life be like if everyone had the same voice? When your parents wake you up in the morning by calling out your name, wouldn’t it be strange if you couldn’t tell who it was calling your name?

We each have a unique voice because so many factors work together to produce that voice. Your voice starts down in your lungs, where air is exhaled to create an airstream in the trachea and across the larynx, which is often called the voice box.

Stretched horizontally across your larynx are vocal folds, which are also known as vocal cords. As air passes over them, the vocal cords vibrate very quickly to produce sounds. The
higher the rate of vibration, called frequency, the higher the pitch will be. The pitch of your voice is largely determined by the length and tension of your vocal cords.

By themselves, the vocal cords produce just a buzzing sound. The parts of your body between the vocal cords and the outside world, such as the throat, nose, and mouth, act as a resonating chamber to turn those buzzing sounds into your unique human voice.

As you can see, there are many different parts of the body involved in producing your voice. Each of those parts is unique in each person, which is what gives each person a unique voice.
