This document discusses various approaches to discourse analysis, including:
1) Speech act theory which views language as performing actions and analyzes utterances based on illocutionary force.
2) Interactional sociolinguistics which examines how context influences production and interpretation of discourse through cues like intonation.
3) Ethnography of communication which analyzes speech events within their social and cultural contexts using Hymes' SPEAKING framework.
4) Conversation analysis which identifies turn-taking and adjacency pairs as fundamental units and examines how conversation is achieved interactively.
