초록

By conducting a production experiment, this study aimed at examining focus prosody in English and Korean to identify the similarities and differences between the two languages. Six native speakers of each language participated in the production experiment and produced target sentences that contained either broad focus and discourse-new focus constituents. The two focus types (that is, broad vs. discourse-new) were directly compared for acoustic analysis. A series of random forests analysis was also conducted to determine which acoustic cue was most important in distinguishing discourse-new focus from broad focus in each language and to spot the most important cue contributing to the differences between English and Korean focus prosody. The results revealed that discourse-new focus realized with sufficient prominence was clearly distinguished from broad focus in each language, supporting the claim that a focused element is maximally prominent within a sentence (Truckenbrodt 1995). However, the findings of the random forests analysis demonstrated that different cues behaved differently in the focus prosody of each language. This study, therefore, argues that the way to realize focus prosody is not uniform across languages, mainly because of languages’ different prosodic structures.

Abstract

By conducting a production experiment, this study aimed at examining focus prosody in English and Korean to identify the similarities and differences between the two languages. Six native speakers of each language participated in the production experiment and produced target sentences that contained either broad focus and discourse-new focus constituents. The two focus types (that is, broad vs. discourse-new) were directly compared for acoustic analysis. A series of random forests analysis was also conducted to determine which acoustic cue was most important in distinguishing discourse-new focus from broad focus in each language and to spot the most important cue contributing to the differences between English and Korean focus prosody. The results revealed that discourse-new focus realized with sufficient prominence was clearly distinguished from broad focus in each language, supporting the claim that a focused element is maximally prominent within a sentence (Truckenbrodt 1995). However, the findings of the random forests analysis demonstrated that different cues behaved differently in the focus prosody of each language. This study, therefore, argues that the way to realize focus prosody is not uniform across languages, mainly because of languages’ different prosodic structures.
