Phonetics

1. Articulators Above the Larynx

this image represents the parts of the vocal tract

All the sounds we make when we speak are the result of muscles contracting. 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 nose; we call the part comprising the mouth the oral cavity and the part that leads to the nose 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.
