From Scottish Gaelic Grammar Wiki
Phonetics is the study of speech sounds. It is usually separated into three subfields of study:
- articulatory phonetics, which studies what is involved with making the mouth create the sounds of language.
- acoustic phonetics, which studies the physical properties of the stream of air of speech sounds.
- auditory phonetics, which studies the way in which the human ear processes speech sounds.
