Answer 2

Explanation:

Although some people might sound quite a bit alike, no two voices are ever exactly alike. 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 sound of each individual's voice is entirely unique not only because of the actual shape and size of an individual's vocal cords but also due to the size and shape of the rest of that person's body, especially the vocal tract, and the manner in which the speech sounds are habitually formed and articulated.
