@TECHREPORT{AICPub490:1990, AUTHOR={Bear, John}, TITLE={Backwards Phonology}, ADDRESS={333 Ravenswood Ave., Menlo Park, CA 94025}, INSTITUTION={AI Center, SRI International}, MONTH={Apr}, NUMBER={482}, YEAR={1990}, KEYWORDS={Phonology!Backwards, Natural Language!Phonology}, ABSTRACT={This paper constitutes an investigation into the generative capabilities of two-level phonology with respect to unilevel generative phonological rules. Proponents of two-level phonology have claimed, but not demonstrated, that two-level rules and grammars of two-level rules are reversible and that grammars of unilevel rules are not. This paper makes ``reversibility’’ explicit and demonstrates by means of examples from Tunica and Klamath that two-level phonology does have certain desirable capabilities that are not found in grammars of unilevel rules.} }
