Nucleus Survey in Some Syntactic Phrases Based on Optimality Theory; A Case Study of a Deaf Student's Speech

In recent years, a constraint-based framework adapted from Optimality Theory to describe and [1]analyses Speech language disordes. This article describes the syntactic structure of student “A” who is a persian male deaf student, based on violation nucleus constraints in the syntactic phrases. In this paper, we first briefly discuss about of Optimality Theory and then, some of sentences that has been obtained from this student by Speech Language pathologist analyses and describes. We find that, we could described and analysed syntactic disorders by Optimality Theory. Analasys and explaining the student’s sentences give us depper understanding of his syntactic structure. By this presuposition, we must supress markedness constraints by working on the faithfulness constrains. The faithfulness constraints education, the mentioned syntactic structure will closer and closer to a natural person. It is suggested that in order to fulfill this important point, in the subject of education, the nuclei of each phrase should be taught to the student first, and in the next step, complement should be gradually added to the nuclei.
