The Conception of Complexity in Second Language Speech Production

The purpose of this paper is to reconsider the concept of second language acquisition. Studies on speech production will be taken up and discussed in terms of three language dimensions: accuracy, fluency, and complexity. The notion of complexity is not clarified yet, compared with the others. It is suggested that the complexity of speech should be made clarified by observing how dialogues are collaboratively constructed in language classrooms. We expect that it will lead to a reframing of our understanding for the idea of second language acquisition and give us a new perspective on second language learning
