【摘要】：本文以汉英元音的相似度为基础,考察美国学习者对汉语元音的习得情况。通过计算学习者和母语者的元音距离分析学习者汉语元音的准确性,通过学习者与母语者元音范畴对比,分析学习者的元音偏误。跨语言语音相似度与二语习得的关系表现为,两种语言间语音的感知相似度决定了母语对二语发音的影响程度,相似度越高影响越大,相似度越低影响越小。对于感知相似度较高的音段来说,当声学相似度与感知相似度的结果差距较大时,母语的影响会相应减小。语言间的相似度也会影响二语发音的准确度,两种语言中完全一致的音段和相似度较低的音段其发音准确度较高,而两种语言中存在一定相似性的音段的发音准确性较低。对于这些相似的音段来说声学相似度决定其发音的准确度,声学相似度越小,发音准确度也越低。
[Abstract]:Based on the similarity of Chinese and English vowels, this paper investigates the acquisition of Chinese vowels by American learners. The accuracy of Chinese vowels is analyzed by calculating the distance between learners and native speakers, and the vowel errors of learners are analyzed by comparing the categories of vowels between learners and native speakers. The relationship between cross-language phonetic similarity and second language acquisition is that the perceived similarity between the two languages determines the influence of mother tongue on second language pronunciation. The higher the similarity is, the greater the influence is, and the lower the similarity is, the less the influence is. For segments with high perceptual similarity, the influence of mother tongue will be reduced when the result gap between acoustic similarity and perceived similarity is large. The accuracy of pronunciation is also affected by the similarity between two languages. The accuracy of pronunciation is higher when the two languages are completely identical and those with lower similarity, but the pronunciation accuracy is lower when there is a certain similarity between the two languages. For these similar segments, acoustic similarity determines the accuracy of pronunciation, and the smaller the acoustic similarity, the lower the pronunciation accuracy.
