Mid-term 1 in English Phonetics and Phonology
Articulatory phonetics the study of how the vocal tract produces the sounds of
language.
Phonology maybe used by actors, teachers, computer engineers etc.
Phonology the description of the systems and patterns of speech sounds in a
language.
It studies:
the abstract or mental aspect of the sounds in a language
the actual physical articulation of speech sounds
The phoneme.
Phoneme is a meaning distinguishing sound in a language; it functions
contrastively/ the smallest contrastive unit in the sound system of a language.
When there is a contrast in identical environment we must be dealing with separate
phonemes - when we replace one sound with another, we get another word with
another meaning, therefore that sound must be a phoneme.
There are small shades of sounds that don't distinguish meaning phones. The
different phones that are the realisations of the same phoneme are called allophones.
