Focus and Prosodic Structure

The effects of focus on prosodic phrasing, F0, and duration are investigated paying attention not only to the target of focus but also to the constituents that are outside the domain of focus in Korean. We find that the constituents preceding and following the focused word tend to be dephrased. Dephrasing does not always cover up to the Intonation Phrase boundary contrary to Jun's (1993) claim. Dephrasing caused by focus determines F0 and durational difference between focused and neutral sentences. Syntactic constituency is also shown to playa role in prosodic phrasing.
