The relationships between text or talk and the context are among the basic fields of pragmatic research and an insight into their nature may contribute to a better understanding of language use. In this article, we use the results of an analysis of discourse marker use in two different conversational genres (telephone conversation and television interviews) in an attempt to examine the impact of context on the use of discourse markers, generalized for each analysed genre. In the first stage of the analysis, we observe important differences between the two genres: discourse markers are far more frequently used in telephone conversations than in television interviews. In the second stage of the analysis, we identify several contextual factors which contribute to the differences in the use of discourse markers. In this way, we obtain insight into this particular aspect of genre context-talk relationships, and identify some of the characteristics of the genres in question.
