vi 中文摘要 中文摘要 中文摘要 中文摘要 本研究旨在探討英語學習者對比重音應用鷹架於自動語音分 析系統，訓練方式、
學生的英文程度及對比重音類型，被視為三個 可能影響對比重音應用的自變數。研究對象為四十三位台灣中部一 所大學 的英語系大一學生，他們是三班英語會話課程的學生，依據 他們的英語會話成績分為高低兩個程度，因此共有二十二位高 程度 及二十一位低程度學生。 對比重音應用的訓練為期六週，每兩週涵蓋一個對比重音類 型，每個類型訓練前後分別實 施前測及後測。訓練方式有三種:教 師教學加上 ASAS 練習、ASAS 練習、教師教學及紙本練習。對比重 音的三種類型則 為: 雙物件、單物件、不完全雙物件。學生前測及 後測的發音及音調成績利用二因子共變數分析、二因子變異數分 析、成 對樣本 t 檢定進行分析，問卷資料則採用適合度考驗探知學 生對於 ASAS 的觀點。主要發現如下: 一、 自動語音分析系統 有改善學生對比重音應用的潛力，尤其 在發音的糾正上。 二、 內容較複雜的對比重音對學生造成較高的學習困難。 三、
高程度的學生透過自動語音分析系統學習對比重音進步比 低程度學生顯著，但對於音調的學習，所有學生需要老師的 講 解更甚於使用自動語音分析系統練習。 四、 大部分學生對自動語音分析系統持正面態度，也願意推薦他 人使用。 本研究 的資料分析結果顯示自動語音分析系統有助於提升學 生的學習動機及口語能力，但老師的教學仍為不可或缺的一部分，
尤其是在學生遇到困難及涉及高層次認知的教學內容時。針對較困 難的對比重音應用，教師的講解並配合自動語音分析系 統的協助， 更能提升學習效益。
關鍵詞 : 自動語音分析系統、自動語音辨識系統、對比重音 目錄
