英语齿间辅音的变体发展与优选论分析

通过词汇朗读、文章朗读、复述故事和访谈四项口语任务,从控制和随意语体两方面考察英语齿间辅音的变体发展模式.结果发现,低水平组对所处单词内部语音环境比口语任务和语体更敏感;中等水平组的发音在不同语音环境和语体中均有较大差异;高水平组不受语音环境影响,但仍然受到语体的制约.通过运用优选论对实验结果进行分析,认为在英语齿间辅音的习得过程中,涉及语音信息处理的语体为更高级别的制约条件.

Variable Development of English Interdental Consonant and Optimality Theoretic Account

This paper examines the variable development of English interdental consonant through four speech tasks,i.e.word list,passage reading,retelling and interview,in controlled and spontaneous speech.The findings show that the low-level group seems more sensitive to the phonetic environment within word than the speech task and style;there is a marked difference in both the phonetic environment and the style for the middle-level group.The high-level group is free from the influence of phonetic environment while still constrained by the style.An optimality theoretic study of the experimental results indicates that the style involving information procession is the higher ranking constraint in the acquisition of English interdental consonant.
