本研究考察了母语为英语和西班牙语的人在语音输入和英语单词的语音表征之间的假设不匹配的影响。英语测试词，这是由NE扬声器和NS扬声器产生的，在词频和邻域密度正交变化，并呈现给NE听众和NS听众谁在英语发音水平不同。据推测，语音表征和语音输入之间的不匹配会损害单词识别，特别是对于来自密集词汇社区的项目，这些项目在语音上与许多其他单词相似，需要更精细的声音辨别。此外，本研究假设二语语音表征会随着二语水平的提高而改变。结果表明，预期的不匹配效应，只有从密集的社区的话。对于西班牙口音的刺激，NS组认识到更多的话，从密集的社区比NE组。对于本机产生的刺激，低熟练NS组识别的单词比其他两组少。高水平NS参与者的表现一样好，NE组的单词从稀疏的社区，但不是从密集的社区的话。这些结果进行了讨论，在有关的发展的语音表示的L2单词。(200话）。(C)2005年美国声学学会。
This study examined the effect of presumed mismatches between speech input and the phonological representations of English words by native speakers of English (NE) and Spanish (NS). The English test words, which were produced by a NE speaker and a NS speaker, varied orthogonally in lexical frequency and neighborhood density and were presented to NE listeners and to NS listeners who differed in English pronunciation proficiency. It was hypothesized that mismatches between phonological representations and speech input would impair word recognition, especially for items from dense lexical neighborhoods which are phonologically similar to many other words and require finer sound discrimination. Further, it was assumed that L2 phonological representations would change with L2 proficiency. The results showed the expected mismatch effect only for words from dense neighborhoods. For Spanish-accented stimuli, the NS groups recognized more words from dense neighborhoods than the NE group did. For native-produced stimuli, the low-proficiency NS group recognized fewer words than the other two groups. The-high proficiency NS participants' performance was as good as the NE group's for words from sparse neighborhoods, but not for words from dense neighborhoods. These results are discussed in relation to the development of phonological representations of L2 words. (200 words). (C) 2005 Acoustical Society of America.
