摘　　要：韩语塞音三分为送气塞音、松塞音和紧塞音,是近几年国外语音学研究的热点之一。本研究基于Global Phone语音语料库中的朗读语料,考察韩语塞音VOT的变异性。研究发现:女性和年轻人群的送气音与松音VOT较接近;后接元音为非高元音时,送气音与松音VOT差异较小;语速越快,送气音与松音VOT差异越小。本文从语音演变角度分析了韩语塞音VOT在年龄、性别、后接元音高度和语速方面存在变异性的根源,并对我国韩语塞音教学提出了相关建议。Korean stops show a three-way contrast of aspirated vs.lax vs.tense stops,and the study of Korean stops is a hot topic in phonetic research overseas recently.This study investigates the variability in VOTs of Korean stops,using read speech data in Global Phone speech corpus.The study finds that:1)VOTs of aspirated stops and lax stops are closer for females and young speakers than for males and old speakers;2)when the following vowel is non-high,the differences between VOTs of aspirated stops and lax stops are smaller;3)VOTs of aspirated stops and lax stops are closer in fast speech than in slow speech.From the perspective of sound change,this paper discusses the origins of VOT variability in age,gender,vowel height,and speech rate.Based on the results and discussions,the paper provides some suggestions for teaching Korean stops in China.
