The purpose of this study is to consider what interaction perspectives can contribute to language research and education. Among other things, the study aims to point out the atmosphere centered on written language, and which has been taken for granted in research and education, to emphasize the need for attention and study on speech and spoken language. It will also argue that attempts are required to reconsider whether the application of the sentence unit is appropriate and to set the intonation and clause as a unit in the research and education for spoken Chinese.
