不同的（cid：11）语言有时使用不同的（cid：11）声学方式来传输相同类型的语言信息。这一事实让我们很容易假设学习者倾向于以母语而非学习语言的方式传递信息。虽然英语单词重音在语言上与日语单词重音几乎相同，但两种语言之间的单词重音在声学上有所不同(cid:11)。本文旨在自动检测生成的单词重音并评估其生成方式。通过使用上下文相关的 HMM，重读和非重读音节的结构和在单词中的位置被分别建模。结果表明，开放实验中 90% 的重读音节被正确检测。在匹配过程中，从不同（cid：11）参数得出的每个似然得分都乘以其加权因子。检测因素的最佳组合可以被认为反映了（cid：13）每个说话者自己的口音生成方式。日语和母语者之间的准最佳组合的差异（cid：11）主要与之前针对外国学习者的英语教学研究报告的（cid：12）结果一致。
Di(cid:11)erent languages sometimes use di(cid:11)erent acoustic man-ners to transmit the same kind of linguistic information. This fact lets us easily suppose that learners tend to transmit the information in a manner of not a language to learn but their native language. While English word accent is linguistically almost the same as Japanese one, the word accent acoustically di(cid:11)ers between the two languages. This paper aims at automating the detection of the generated word accent and the evaluation of how it is generated. By using context-sensitive HMMs, stressed and unstressed syllables were modeled separately for their structure and for their position in a word. Results showed that 90% of the stressed syllables were correctly detected in open experiments. In the matching process, each of the likelihood scores derived from di(cid:11)erent parameters was multiplied with its weighting factor. The optimal combination of the factors for the detection can be thought to re(cid:13)ect each speaker’s own manner of the accent generation. Di(cid:11)erences of the quasi-optimal combinations between Japanese and native speakers mainly accorded with (cid:12)ndings reported in previous studies on English teaching to foreign learners.
