Three traditional branches are generally recognized:
1) articulatory phonetics is the study of the way speech sounds are made by vocal organs;
2) acoustic phonetics studies the physical properties of speech sound, as transmitted between mouth and ear;
3) auditory phonetics studies the perceptual response to speech sounds, as mediated by ear, auditory nerve and brain.
The fourth branch - ''functional phonetics'' - is concerned with the range and function f sounds in specific languages. It is typically referred to as phonology.(c) Professor Paraschuk
