語氣詞在華語母語者的對話當中，扮演了重要的角色。而語言因為時間和空間的遷移，也會產生不同的變化。因此本文針對兩個華語使用區域─台灣和馬來西亞的華語語氣詞使用異同。 本文採用情境構擬的方式對30位受試者採集貼近真實的語料。情境構擬實驗以齊滬揚(2002)提出的六大語氣分類為本，加上感嘆、或然及提醒類的情境，設計出九種類型語氣的題目進行實驗。本文更依據情境構擬語料結果中找出台灣地區常用的六種語氣詞，與中央平衡語料庫的語料進行對比，進一步確認語氣詞功能是否一致。 台馬兩地常用的語氣詞，其中相同的語氣詞有：「啊、吧、嗎、了、誒」，台灣獨有的「哦」及馬來西亞常用的「咧」。其中，「了」雖然兩地皆用，但發音不同，台灣發為「lɤ2」，而馬來西亞發為「liau3」。本文找出的常用語氣詞和過去學者統整的有相同和相異之處，判斷原因有三個：一、資料來源不同；二、語言變化(時間和空間的影響)；三、區域性差異。 / Modal particles are very important in Mandarin Chinese. By just adding one modal particle to a sentence, speakers are able to express their various feelings, moods or attitude. Language always changes because of differences in time and space. This study focuses on two areas of Mandarin usage, Taiwan and Malaysia, to discover the differences in use of modal particles between them. In this study, we attained authentic materials by situational conversations with 30 subjects. The situational conversation based on Qi (2002) mentions 6 kinds of traditional modals plus 3 types (sigh, contingent and reminder) which are used to design a modal particle experiment. This study not only focuses on authentic materials, but also uses Sinica Corpus to verify the functions of the modal particles. The common modal particles used in Taiwan and Malaysia are “a, ba, lɤ, e”. One that is only used in Taiwan is “O”, and in Malaysia is “le”. Although these two countries actually use “le”, the pronunciation is different.
