The prosodic analysis of Korean dialogue speech-through a comparative study with read speech

The paper describes the prosodic features of Korean dialogue speech. With 25 sentences for scheduling, one speaker uttered in two manners, viz. `read´ and `dialogue´. The main discriminating features would be some aspects in speech rate and boundary signal. The authors discriminated each prosodic phrase in a sentence to investigate pre-boundary, boundary, and post-boundary features. The durational aspect in dialogue speech shows much more drastic characteristics than that in read. They can see that the boundary syllables of dialogue seem to be 2.3 times longer than that in preboundary syllable. The final syllables are about 1.7 times longer than prefinal syllables. Pitch analysis shows that dialogues are pronounced 14.3% higher than read. The emotional factor of dialogue seems to raise the average pitch. It was interesting that the minimum pitch values are about 72% of sentential mean for both similarly. In dialogue, there was great difference between the pitch of prefinal and that of final syllable, i.e., the final syllables are almost 15 % higher. The results confirms our general ideas that 1) the duration is more dynamic in dialogue than in read speech, 2) pitch contour fluctuation is larger in dialogue than in read speech, 3) dialogue is usually uttered in higher tone, 4) and sentential final part may play an decisive role in speech style determination
