The main purpose of this study is to provide an explicit analysis of speech errors in cross-linguistic transfer by using Recursive Constraint Demotion algorithm (Tesar & Smolensky 1998, 2000, Tesar 1998, Prince 2002) within the framework of Optimality theory (Prince & Smolensky 1993, McCarthy & Prince 1995). This study focuses on the examples that cause speech error where Korean phonological grammar, especially with regard to nasalization and lateralization, affects English pronunciation. Language learning simply means knowing the constraint hierarchy, since constraints are basically universal and language variation results from different rankings of constraints, according to the basic concept of OT. Therefore, this study pursues how Korean learners of English erroneously use native grammar (nasalization and lateralization), and confirms what happens when Korean grammar is applied to English pronunciation. In addition, variational speech error in Korean-English transfer (either mis-applied nasalization or laterlization to English) is also explained. This study shows that variational speech error results from speakers different usage of morphological structure for a given word.
