Language has many interesting, apparently complicated effects.   Linguists typically explain these by discrete rules on discrete objects, such as “a /stop t/ should be transformed to a /flap t/ when in the middle of an unstressed syllable”.   This is phonetics – operations on discrete entities.    Phonology is the physical implementation of these discrete entities, and is often considered relatively unimportant.    I’ll show in this talk that with a physically reasonable model, the phonetics (I.e. the strategy that the brain uses to control the articulators) can explain much that is normally considered to be phonology.
