This article discusses the verbal and embodied resources used by participants in turn-taking practices in two contexts of public interaction in Colombia: a radio broadcast and a public discussion on feminism. The general format of the interaction is an interview. In the radio broadcast, five participants are interviewers and one is interviewee; in the public discussion, three are interviewees and one is interviewer. An animator is present in every interaction to allocate turn. We analyze the video-taped corpus focusing on multimodal practices mobilized by speakers for other-selecting and self-selecting speaker in both contexts, observing participants' orientation and action according to their roles, notably animator, interviewer, and interviewee.
