Declarative Phonology
The YorkTalk/IPOX research draws from and contributes to the field of Declarative Phonology
(Bird 1991).
Goals:
- formalize non-linear (metrical and auto-segmental) phonology
- add phonology to declarative, constraint-based theories of language (e.g. HPSG)
- formulate a maximally restrictive theory of phonological well-formedness
Properties:
- non-derivational
- mono-stratal (no levels of representation)
- non-destructive (no deletion rules)
- no extrinsic rule ordering
- surface-based
Differences with Optimality Theory
(Prince and Smolensky 1992):
- conflicts between constraints are not allowed (but see Ellison 1994)
- emphasis on computational implementation
