The Human Voice

Human voice can express difficult ideas through a variety of arrangements of consonant and vowel sounds. It can be also be used for singing. It can combine speech with music, and sing words. With his highly developed voice, man has developed elaborate languages. These allow us to tell each other the most exact details of our thoughts and actions.

The vocal cords are the main sound producers in man. These two small bands of tissue stretch across the Larynx( voice box). One band stretches on each side of the windpipe opening. Muscles in the Larynx stretch and relax the vocal cords.

When we breath, we relax our vocal cords so they form a V-shaped opening that lets air through. When we speak, we pull the vocal cords by the attached muscles, narrowing the opening, Then, as we drive air from the lungs through the Larynx, the air vibrates the tightened vocal cords and sound results.
