汉语内部方言众多,不同的方言具有特定的语音系统和发音规律,方言区英语学习者的发音受汉语方音(Chinese dialectal pronunciation)的影响,会不自觉地将方言(母语)中的语音规则,套用到英语发音中,往往造成发音偏误,偏误的类型因方言差异而不同。为解决中国英语学习者面临的语音问题,研究提出构建大规模方言区英语学习者语音库AESOP-CASS,语音库方言点涵盖中国十大方言区,语料内容包括英语语料,方言语料和方言普通话语料,基于语料库可以对方言区英语学习者语音进行系统研究,将语音学中的参数VOT、共振峰、语调音系模式等特征用于英语学习者偏误分析,可针对不同方言区学习者提出不同的矫正方法。
There are many dialects in Chinese, and different dialects have specific phonetic system and pronunciation rules. The pronunciation of English learners in dialects is influenced by Chinese dialectal pronunciation, and unconsciously uses the pronunciation rules in dialects (mother tongue) When applied to English pronunciation, it often causes the pronunciation error, and the type of the error is different due to the dialect differences. In order to solve the problem of Chinese EFL learners, AESOP-CASS, a large-scale dialect-based English learner speech library, is proposed. The dialect contains seven Chinese dialects. The corpus includes English corpus, dialect corpus and dialect Mandarin Corpus, based on the corpus, can systematically study the pronunciation of English learners in dialect area. The characteristics of phonetics such as VOT, Formant, Phonetic Phonetic Pattern can be used in English learner’s error analysis. It can be proposed for learners in different dialects Different methods of correction.
