This study explores Korean phonotactic grammars, focusing on laryngeal co-occurrence restrictions. This paper is composed of two main parts. In the first part, using a Maximum Entropy Model of Phonotactic Learning (Hayes and Wilson 2008), I ran a learning simulation for Native and Sino-Korean lexicons. Based on the statistical patterns of each lexicon, phonotactic constraints were created with their own weights, the magnitude of which reflects their gradient strength. Especially, the constraints of laryngeal marked features were learned. The resulting native grammars include laryngeal co-occurrence restrictions. On the other hand, Sino-Korean grammars include constraints with the tense feature. The latter part of this study concerns the psychological validity of laryngeal co-occurrence restrictions. A well-formedness judgment test was conducted with native speakers of Korean. The test results suggest that Korean speakers are aware of most laryngeal co-occurrence restrictions and the constraints with the tense feature which are part of the learned grammars. It is also shown that native and Sino-Korean grammars make independent contributions to explaining speakers’ judgments found in the present experiment. In sum, this research shows that Korean phonotactic grammars can be learned from the lexicons of Korean, and that at least some important parts of the learned grammars are psychologically real.
