中国学生韩语初声发音偏误声学评价标准研究

A Study of the Acoustic Evaluation Standards for Korean Onset Pronunciation Errors of Chinese Learners

本文旨在针对中国学生的韩语初声发音偏误提出一套声学评价标准,以弥补实际发音矫正教育中客观有效的评价标准缺失这一空白。文中把中国学生的韩语初声发音偏误分为松音和送气音的混淆、松音和紧音的混淆、?发音偏误、?发音偏误、?发音偏误等五个类型。对各个偏误类型分别提出与语音的发音语音学特征相对应的声学指标,如VOT值、F0值、发音时长、强度曲线凹度、Formant值等。

This study is aimed to present a set of systematic evaluation standards for the Korean onset pronunciation errors of Chinese Learners so as to establish a pratical set of evaluation standards in the area of correcting training of Korean pronunciation. The pronunciation errors of Chinese learners are divided into ifve types：confusing lenis and aspirates, confusing lenis and fortis,？pronunciation error, ？pronunciation error, and？pronunciation error. The study proposes such acoustic indexes that are related to the articulatory phonetic features as VOT value, F0 value, length, relative concavity of the intensity curve and formant value.
