第二言語学習者における発話行為の産出に関する研究

―分析の着眼点を中心に―

抄録

Based on an analysis and summary of recent research, its achievements and shortcomings regarding the production of speech by second language learners are examined. Because several factors influence the production of speech, it is necessary to analyze the overall situation of the production from various viewpoints. Until now, most publications on speech production have focused mainly on three issues: the content of language expression, language fluency, and the cognitive processes involved. Although the types of speech acts that have been studied are extensive, and the research has varied in approach, most studies have focused on the content of language expression. Besides, language fluency and cognitive processes received much less attention than the content of language expression. However, research on language fluency and cognitive processes is very useful for improving the efficiency of learners' knowledge processing abilities, which constitute an important aspect of learners' speech production. Finally, research trends on the production of speech by second language learners are discussed based on the analysis of the results and shortcomings of current research.
