Dialogue implies a high degree of coordination between the interlocutors, which makes possible the existence of co-constructed turns used by speakers for various purposes. One of the reasons for them to appear is difficulties in articulation experienced by one of the participants and prompting the other participant interested in achieving the communicative goal to increase their own contribution to the dialogue. In conversations with people who stutter, co-constructions are more common than in conversations between people who have no diagnosed speech disorders; among them completions prevail, because one of the interlocutors more often spells out uncompleted constructions. The study of stuttering from a linguistic perspective is of considerable interest, since it provides an opportunity to study dialogue as a process including cooperation between participants. During this collaborative process one interlocutor’s contribution affects the contribution of another and can trigger non-standard turn-taking techniques.
