This study investigated (1) whether Korean learners of English use discourse-level prosody in L2 production as nativespeakers of English do, and (2) whether discourse-level prosody is also found in the Korean language, as is evident in theprosody of native speakers of English. The study compared the production of the same 15 sentences in two types of readingmaterials, sentence-level and discourse-level. This study analyzed the onset pitch, sentence mean pitch and pause length toexamine the paratone (intonational paragraph) realization in discourse-level speech. The results showed that in L2discourse-level prosody, the Korean speakers were limited in displaying paratone and did not made significant differencebetween sentence-level and discourse-level prosody. On the other hand, in L1 discourse-level text, both English and Koreanparticipants demonstrated paratone using pitch. However, there were differences in using prosodic cues between two groups. In using pauses, the ES group paused longer before both the orthographically marked and not marked topic sentences. TheKS group paused longer only before the orthographically marked topic sentence in both L1 and L2 text reading. In thecomparison of sentence-level and discourse-level prosody, the topic sentences were marked by different prosodic cues. Englishparticipants used higher sentence mean pitch, and the Korean participants used higher onset pitch.
