影响学习者西班牙语塞音感知的声学特征分析

Acoustic Analysis on Chinese Learners' Perception of Spanish Plosives

在高变化性语音训练实验框架下对学习者西班牙语塞音混淆进行声学分析,结果显示,学习者对西语塞音的混淆与其爆破能量变化速率显著相关。发声特征作为音位区别特征在普通话中的缺失是造成混淆的主要原因。外语语音训练效果的最大化有赖于对学习者进行音位区别特征的明确指导。

A high-variability phonetic training was carried out on native Chinese learners＇ identi- fication of Spanish consonants. Chinese learners＇ identification performance was significantly correlated with its speed of relative energy release during burst. We believe that it was the missing of voicing as a distinctive cue in Chinese led the learners turned to focus on such a non- robust acoustic cue in Spanish plosive identification. To maximize the effect of high-variability training, explicit instruction on major distinctive cues between the contrastive sounds in the target language is necessary.
