In this study we investigate produced and perceived pauses in relation to thematic units of Greek radio news, defined by both listeners and readers. The results indicate: (1) perceived pauses are more than both produced pauses and thematic units; (2) the number of thematic units by listeners and readers does not differ substantially; (3) an agreement of ≥ 80% among listeners and readers results in a substantial drop of thematic units; (a) neither short and long pause nor hypertheme and hypotheme categories are adequately perceived.
