漢語音節由聲母及韻母所構成,聲母一般都是以輔音為主,而韻母則多以元音為主,其中元音部份由於不受口腔內發音器官的節制,於其響度問題上頗有可供研究之空間。雖然前人對此多有討論,但其內容往往未盡精確或模稜兩可,特別在於以前後元音相互比較時,其響度大小之結果究竟孰強孰弱,各家說法迭有不同。於是本文擬借趙元任先生「國際音標讀法」為範本,就其中所收元音部份,利用PC平臺上音訊專用之軟體試加分析,希望借此能夠得到兼具科學與客觀性質的數據資料,並就此份資料中所呈現的若干現象加以探討,同時徵引現今數家載籍中有涉響度之論述,藉以與本文所得結論相驗證,以期對元音響度此問題能有更為深入的瞭解。
Chinese syllable is the finish product combining the initial and the final. The initial mainly focuses on the consonant, and the final often uses compound vowel that does not control by vocal organs. There are still researchable field in the sonority. The field itself was debatable from predecessors; however the content is often equivocally. Especially when making comparison between the front vowel and the rear vowel, the sonority of each presentation brings more controversy. This article use "Zhao Yuan-ren" IPA Pronunciation as reference guide that contains the usage of vowel, using the audio editing software on PC to analyze the data hoping to find a much more rational explanation using scientific method.
