國語訊息結構之產生與感知研究

Abstract

本研究同時進行對比訊息與新訊息之產生實驗與感知實驗。主要研究的議題是台灣地區國語受試者是否能感知到對比訊息和新訊息，並探討台灣國語說話者以何種聲學特徵區辨對比訊息、新訊息和已知訊息。感知實驗以對話重建與成對比較方式兩種方式進行。感知實驗結果發現受試者整體而言能夠重建答句中帶新訊息和單一對比訊息之前行問句；亦能經由成對比較判斷對比訊息和新訊息。本研究的產生實驗以看圖問答之自然對話方式獲得語料。結果顯示兩位發音人無共同的聲學表現方式，個別亦無一致表現於四個字調的聲學特徵。

This study does the research on perception and production of contrastive and new informations in Taiwan Mandarin. The aims of the study are to see if people whose mother tongue is Taiwan Mandarin can distinguish contrastive and new informations from given information in perception and in production. The perception experiments adopt two experimental designs--dialogue reconstruction and pairwise comparison. The results of dialogue reconstruction show that the listeners can reconstruct new and single contrastive informations. And the results of pairwise comparison show that the listeners can differ new and contrastive informations from given information. As for the production experiment, a dialogue game was played to obtain acoustic data. The results of the production demonstrate that no common acoustic cues are used by the two subjects. Besides, no common acoustic features are found in the four tones for each subject.
