Little research has focused on extended concurrent speech, unexpected floor taking, or topic switching, since it has been deemed rare (Schegloff 2000. "Overlapping talk and the organization of turn-taking for conversation." "Language in Society" 29(1). 1-63.) or inappropriate (Goldberg 1990." Interrupting the discourse on interruptions: An analysis in terms of relationally neutral, power- and rapport-oriented acts." "Journal of Pragmatics" 14(6). 883-903; Giora 1998. "Discourse coherence is an independent notion: A reply to Deirdre Wilson." "Journal of Pragmatics" 29(1). 75-86). This study integrated Spencer-Oatey's (2008. Face, (im)politeness and rapport. In Helen Spencer-Oatey (ed.), "Culturally speaking: Culture, communication and politeness theory", 11-47. London: Continuum) rapport management model with the community of practice model (Wenger 1998. "Communities of practice: Learning, meaning, and identity". Cambridge: Cambridge University Press) to investigate extended concurrent speech for floor taking or topic switching. Data were derived from approximately 49 hours of conversations at the English-Corner community of practice and follow-up interviews with ten of the participants. Interactional sociolinguistic methods were employed. Extended concurrent speech for floor taking or topic switching was found to be used as a resource for rapport management. Most of the instances appeared to be face-maintaining and rapport-maintaining; some were face-enhancing and rapport-enhancing. The few potentially face-threatening instances turned out to be rapport-maintaining. These might result from the participants' interactional goals, rights preservation, or identity revelation/negotiation, and the informality of the context. The ten interviewees provided insights that corroborated the analysis.
