香港说广州话的学生习得普通话咝音声母的研究

Acquisition of the Mandarin Sibilant Consonants by Cantonese-speaking Students in Hong Kong

本文从发音和听辨两方面去分析八位说广州话的香港学生对普通话三组咝音声母[s ts ts^h]、[ʂtʂtʂ^h]、[ɕtɕtɕ^h]的习得。经声学分析取得咝音噪音的LPC能量峰值,发现这些广州话母语者的三组普通话咝音的发音跟普通话母语者的发音有差异,尤其是[s ts ts^h]和[ɕtɕtɕ^h]的发音是接近广州话的[s ts ts^h],显示母语对二语发音的干扰。此外,根据十位普通话母语者的听辨评估,发现八位广州话母语者对三组普通话咝音的发音有混淆,降低了整体的发音正确率。不过在听辨方面,八位广州话母语者基本上都能区分三组普通话咝音,显示香港学生在二语学习的发音和听辨能力不同。研究结果让我们对广州话母语者习得普通话的咝音声母有新的认识。

This study investigates the production and perception of the Mandarin sibilant consonants[s ts ts^h],[ʂtʂtʂ^h]and[ɕtɕtɕ^h]by eight Cantonese-speaking students in Hong Kong.Results of acoustic analysis of the noise energy of the sibiliants show that both the Mandarin sibilants[s ts ts^h]and[ɕtɕtɕ^h]uttered by Cantonese speakers are similar to the Cantonese sibilants[s ts ts^h].The finding indicates the first language's interference in the pronunciation of the second language.Furthermore,the perceptual assessment performed by ten native Mandarin speakers shows that there is confusion among the pronunciations of the three sets of Mandarin sibilants in the speech of Cantonese speakers,resulting in the lowering of the rate of correct pronunciation.In perception,the Cantonese speakers are able to distinguish the three sets of Mandarin sibilants,an indication that there is a difference in the abilities of production and perception in second language acquisition.The findings in this study provide some fresh implications for the acquisition of the Mandarin sibilants by Cantonese speakers.
