This document discusses key concepts in conversation analysis. It explains that conversation analysis looks at everyday spoken discourse to understand how people manage interactions and develop social relations. Conversation analysis involves transcribing recordings of conversations, where the transcription itself is part of the analysis process. Transcription conventions are used to systematically represent speech. Aspects of conversational structure that are examined include openings, closings, turn-taking, sequences of related utterances known as adjacency pairs, and preferences for certain responses.
