Experimental Research on the Modal function of Two Adverbs Dao and Que

摘要

While voice information processing is moving from static and physical research towards dynamic and functional research, experimental research on mood has become a necessity. Based on experiment on the modal function of the two adverbs Dao and Que, this thesis proposes the following points: 1. Both Dao and Que can effectively express mood, which is supported by the change of F0 and volume increase of the phonological words before and after Dao and Que in the experimental sentences; 2. In normal cases, Que is more effective than Dao in expressing a strong mood, which is proved by how each of them affect the F0(including pitch range) of a sentence, the duration of a whole sentence and the pause between clauses. 3. The different performances of the two words in regard to their modal function are represented by F0, intense, duration etc.
