概要	Multiple case-based conversation analysis applies the fine-grained sequential methods of Conversation Analysis (CA) across two or more distinct cases — settings, groups, or interactions — to identify both case-specific patterns and cross-case regularities in naturally occurring talk. By examining how participants organise turn-taking, repair, and action sequences in multiple contexts, the approach strengthens claims about interactional phenomena beyond what a single-case study can establish.	Comparative Conversation Analysis (comparative CA) applies the rigorous micro-analytic methods of Conversation Analysis across two or more contrasting interactional settings, languages, cultures, or participant groups. It examines how the sequential organisation of talk — turn-taking, repair, adjacency pairs, and action formation — varies or remains stable across contexts, producing cross-contextual evidence about the architecture of human interaction.
