How a Voice is Produced The vocal cords, of course are very important in producing a voice. They are positioned at the top of the trachea, or windpipe, and have the ability to open and close.

The vocal cords coming together, however, will not result in a voice. In fact, the vocal cords do not vibrate independently. In order to produce a voice, the vocal cords must come together, while simultaneously, air from the lungs is exhaled through them in a sufficient manner. The flow of air through the closed vocal cords causes vibrations…the sound we hear as a voice! Consider how leaves rustle in the wind. Vocal cords vibrate like leaves in the wind. Without airflow or “wind,” the vocal cords are still, and no sound will be produced. In this sense, you can understand then, how we exhale the air is just as important as the vocal cords in terms of producing a voice. Dysphonia: When Hoarseness Should Be Addressed Dysphonia is a general term referring to an abnormal voice. Dysphonia usually happens to everyone at some point, and typically resolves without intervention. One common example of this is a laryngitis that may occur with a virus. As the virus resolves, the voice usually returns to normal on its own.
There are times, however, when dysphonia does not improve. In those cases, it is good to see your doctor. In general, a dysphonia may not be an indication of a serious health issue, but it may not improve, or may even become worse, without proper diagnosis and care. Although changes in the voice are common and rarely worrisome, there are indications when voice changes should prompt you to see your doctor:
