This study investigated how two different kinds of prominence-induced prosodic strengthening, identificational focus and contrastive focus, are phonetically realized in Seoul Korean. In the experiment, 16 native speakers produced target sentences presented in three different prosodic conditions: default reading, NP1-contrast, and NP2-contrast. The production data presented three crucial characteristics in the phonetic manifestations of prominence-induced prosodic strengthening in Seoul Korean. First, identificational focus gave rise to temporal expansion and pitch enhancement over the constructions under the focus. Second, contrastive focus brought about modification of temporal, pitch, and prosodic structures as well as pre- and post-focus compression. Finally, the two different types of prominence marking interacted with each other; the prosodic realization of contrastive focus overrode the prosodic realization of identificational focus, which was in line with the formal (syntactic) distinction of the two types of focus. To conclude, the current study demonstrates the interplay of information structure and discourse contexts in prosodic strengthening effects induced by prominence, especially in Seoul Korean, which lacks lexical stress and pitch accent.
