Human voice consists of sound made by a person using the vocal folds for talking, singing, laughing, screaming or crying. The vocal folds in combination with the teeth, the tongue, and the lips, are capable of producing highly intricate arrays of sound, and vast differences in meaning can often be achieved through highly subtle manipulation of the sounds produced (especially in the expression of language). These differences can be in the individual noises produced, or in the overall tone in which they are uttered.

Not studying the human voice, I am assuming that tone and pitched are produced strictly by the manipulation of the vocal cords. Right?
