ORGANS OF SPEECH
All the sounds we make when we speak are the result of muscles contracting. The muscles in the chest that we use for breathing produce the flow of air that is needed for almost all speech sounds; muscles in the larynx produce many different modifications in the flow of the air from the chest to the mouth. After passing through the larynx, the air goes through what we call the vocal track, which ends at the mouth and nostrils (oral cavity and nasal cavity); here the air from the lungs escapes into the atmosphere.

ORGANS OF SPEECH (VISUAL)
We have a large and complex set of muscles that can produce changes in the shape of the vocal tract, and in order to learn how the sounds of speech are produced it is necessary to become familiar with the different part of the vocal tract.
