PHONETICS: Lindblom's theory of Hyper and Hypo-articulation claims that speakers vary articulatory clarity according to
the informational requirements of their listener: speakers hyper-articulate when listeners require maximum acoustic information,
and reduce articulatory effort when listeners can supplement the acoustic input with information from other sources (Lindblom,
1990).
To prevent speakers from over-economising to a point of unintelligibility, hypo-articulation is governed by a constraint of
lexical distinctiveness: speakers hypo-articulate only while listeners are able to distinguish the target from competing lexical
items.
