Phonetics is a branch of linguistics that comprises the study of the sounds of human speech. It is concerned with the physical properties of speech sounds (phones): their physiological production, acoustic properties, auditory perception, and neurophysiologic status. Phonology, on the other hand, is concerned with abstract, grammatical characterization of systems of sounds.
The study of phonetics is a multiple layered subject of linguistics that focuses on speech. In this field of research there are three basic areas of study.
- Articulatory phonetics- the study of the production of speech by the articulatory and vocal tract by the speaker
- Acoustic phonetics- the study of the transmission of speech from the speaker to the listener
- Auditory Phonetics- the study of phonetics of the reception and perception of speech by the listener
- All parts of phonetics are inter-connected because the process of human communication is both a system of auditory mechanisms which correspond to each other and are mediated by wavelength, pitch, and the other physical properties of sound.
