There are many parts of the body involved in the speech mechanism - these include the palate, tongue, voice box (larynyx), respiratory system, and brain. Different parts of the body work together (or in tandem) to produce sound and refine it into human speech that is distinct and recognizable. Sometimes, when these parts of the speech mechanism do not work properly, a person may develop speech problems, including stammering or (in a young child) late development of speech. Occasionally, psychological issues may influence the development of certain speech disorders - for example, stuttering, or stammering, is believed to have a psychological element.

• Parts Of The Speech Mechanism

Respiratory System - In order to process sound, there must be air; in the human body, air enters through the mouth, and oxygen is used to pump the heart and process sound. Without a properly functioning respiratory system (including the lungs), a person may have difficulty with their speech mechanism. One example of a speech mechanism difficulty related to respiratory problems is emphysema, which may cause laboured speech, or wheezing.

Voice Box - The voice box, or larynx, is vital to a proper human speech mechanism; this body part controls the pitch and level of sound. When the larynx is diseased, it may need to be removed via a tracheotomy - unfortunately, this can make regular speech impossible after the operation. In some cases, an electronic voice box can be implanted to produce some degree of sound; however, this will not restore the particular pitch and volume of a person's voice. Diseases that may affect the health of the larynx include cancers of the throat, or opportunistic infections.

The body has many complex processes and systems that work to produce audible and intelligible sound. The speech mechanism of a human being allows men, women, children and infants to express themselves (and their needs) through talking, screaming, whispering, and singing.
