This article centres on the role of the perceptual recoverability of
economical representations in the evaluation of faithfulness constraints
in the production grammar, focussing on phenomena that have been
traditionally described as OCP effects, while noting that these OCP
effects are special cases of a more general process of sequential
perceptual integration. In passing, we note that a grammar model that
wants to incorporate functional principles into phonology and still
maintain economical representations in the lexicon, has to consist of
three different grammars for production, perception, and recognition.
Summarizing the conclusions of the consecutive chapters, the reasoning
goes as follows:
1. The phonological surface form involved in the evaluation of
faithfulness constraints in an Optimality-Theoretic production grammar is
best modelled as an economical lexical-like representation constructed
from the acoustic signal by a language-dependent process of perception.
2. This perception process maps raw sensory data onto discrete structures.
3. 'Perception grammar' is an appropriate term for this perception
process, because this process submits to grammatical modelling and both of
its tasks (categorization, sequential abstraction) are language-dependent.
4. The perception grammar is best modelled as an Optimality-Theoretic
grammar, because there are conflicts within and between its various tasks
(categorization, sequential abstraction), and because the autosegmental
well-formedness conditions that handle sequential abstraction (OCP and
LCC) must be regarded as violable if they are defined in terms of
5. When combined with a recognition grammar and a production grammar, the
existence of a perception grammar that handles categorization and
sequential abstraction ensures compatibility between lexical economy and
phonetically-based ranking of articulatory and faithfulness constraints.
6. The OCP in the perception grammar turns out to handle the linguistic
data well. Faithfulness comes to replace correspondence, uniformity,
anchoring, and alignment. Moreover, expressing the OCP as a violable
constraint in an Optimality-Theoretic production grammar runs into the
problem that faithfulness constraints can force different phonological
surface representations for phonetically identical forms, whereas
expressing the OCP as a violable constraint in an Optimality-Theoretic
perception grammar does not run into this problem.
These points are evidence for the existence of a perception grammar and
suggest that the natural place for constraints that handle sequential
abstraction, i.e. OCP and LCC, is in this perception grammar.
