Original Abstract

The human speech arises when the air stream flows through the glottis (the space between vocal cords situated near the larynx entrance), throat cavity, oral cavity and nasal cavity. Both the nose and lips radiate speech out of the body to free space. The vocal cords are elastic muscles and human beings can stretch them variably and in this manner the speed of their own vibration can determined. The frequency of the vocal cords vibration determines the fundamental period of the speech signal (the basic parameter of the human speech). The high pressure of the air stream (which flows from the lungs) works on the closed vocal cords and they become open. The pressure of the air stream decreases after that and the vocal cords became closed. The situation is repeated. Various amounts of the air stream flows through the glottis in various time points. The relation between amount of the air stream and time corresponds with the glottal pulses for the voiced speech.
