两项研究调查了日语和美国英语（AE）元音的声学和感知相似性。在研究1中，研究人员使用F1、F2和音长作为输入参数，对日语和AE元音进行了一系列判别分析，以确定它们在声学上的相似性。在研究2中，在感知同化任务中，将日语元音呈现给本土声发射听众，听众将每个日语元音标记归类为与声发射类别最相似的，并将其作为所选声发射类别的范例进行评分。结果表明，大多数AE听者将所有日语元音都吸收到长AE类别中，明显忽略了1- mora和2-mora日语元音的时间差异。此外，并非所有的感知同化模式都反映了由判别分析建立的特定情境的光谱相似模式。据推测，这种声学相似性和感知相似性之间的不一致可能是由于影响听者感知判断的本地和非本地元音类别分布特征的差异。(C) 2008美国声学学会。
Acoustic and perceptual similarities between Japanese and American English (AE) vowels were investigated in two studies. In study 1, a series of discriminant analyses were performed to determine acoustic similarities between Japanese and AE vowels, each spoken by four native male speakers using F1, F2, and vocalic duration as input parameters. In study 2, the Japanese vowels were presented to native AE listeners in a perceptual assimilation task, in which the listeners categorized each Japanese vowel token as most similar to an AE category and rated its goodness as an exemplar of the chosen AE category. Results showed that the majority of AE listeners assimilated all Japanese vowels into long AE categories, apparently ignoring temporal differences between 1- and 2-mora Japanese vowels. In addition, not all perceptual assimilation patterns reflected context-specific spectral similarity patterns established by discriminant analysis. It was hypothesized that this incongruity between acoustic and perceptual similarity may be due to differences in distributional characteristics of native and non-native vowel categories that affect the listeners' perceptual judgments.
