People are aware of pronunciation, if not phonology and phonetics. Phonetics is the study of the production, transmission and reception of sounds in human speech and is the subject of careful, informed, scientific investigation. Phonology is the study of the usage of speech sounds in language in general and languages in particular and is the subject of careful, informed, linguistic investigation. Pronunciation, on the other hand, is everyone’s activity in spoken communication; that is what we hear and what we produce in talk; it is everyone’s experience and hence is part of everyone’s business.
