VOICE

The human voice consists of sound made by a human using the vocal folds for talking, singing, laughing, crying and screaming. The vocal folds, in combination with the lips, the tongue, the lower jaw, and the palate, are capable of producing highly intricate arrays of sound.

The tone of voice may be modulated to suggest emotions such as anger, surprise, or happiness.

Singers use the human voice as an instrument for creating music.
