It also describes several models that have been developed for analyzing different types of spoken discourse, such as the Sinclair and Coulthard model for teacher-student interactions. The document notes that discourse analysis examines both spoken interactions and the organization of written texts, seeking to understand how language forms are interpreted based on participants' roles and the social setting.
