Articulatory Phonetics

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 air from the chest to the mouth. After passing through the larynx, the air goes through what we call the vocal tract, which ends at the mouth and nostrils; 

🌟 We call the part comprising the mouth "The Oral Cavity".

and 

🌟 The part that leads to the nostrils "The Nasal Cavity" 

Here the air from the lungs escapes into the atmosphere. 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 parts of the vocal tract.  These different parts are called articulators, and the study of them is called articulatory phonetics.
