    Abstract: 近年時間數列的分類與群集分析,早已經是資料庫/資料採礦社群中極有興趣研究的主題之一。但大多數的分類與群集方法中都需要計算兩不同時間數列的不相似性量數,但當兩時間數列變動的形狀相似但時間軸並不相同時,歐氏距離等量數對時間軸的扭曲是非常敏感的。使用歐氏距離等量數在分類與群集分析中,雖然計算容易,但不可否認的是會面臨錯誤率較高的現象。
    而時間軸偏差的問題可以用動態時軸校正(DTW)法解決,此法可以有效地校正時間軸的偏差,本研究將採用最近鄰居分類法則,來區別與分類多個人說中文”芝麻開門”的語音。由於必須計算出每個
    In recent years, classification and clustering of time series data have become one of the topic of great interest within the database/data mining community. Most method in classification and clustering are needed to calculate the distance measure between
