迄今为止，韵律因素（尤其是语调）对外国口音感知的贡献很少成为第二语言习得研究的主题。在感知测试中，使用低通滤波刺激，这项研究表明，相当数量的听众能够区分美国英语和德语在讲话30秒或更长的时间。听众在直接的配对比较中更成功，表明美国英语和德语的韵律特征是截然不同的，足以促成一个明显的语言特异性差异。相同的测试重复使用低通滤波的刺激与单调的语调。在这种情况下，所有结果都明显更差。因此可以说，语调显然是感知外国口音的最重要的韵律因素。语调的相关性也验证了在外国口音评级任务和直接对比较使用原来的外国口音的美国英语的话语由母语为德国和F0生成和重新合成的版本中，语调错误得到纠正。最后，本研究还试图通过比较完全合成的版本的扬声器的原始话语（没有段外国口音，但语调外国口音）和F0生成的，“改进”的版本（没有语调，但段外国口音）的评级，给人的印象的相应份额的分段和语调方面。结果表明，音段体对外国口音的感知有较大的影响。
As of yet the contribution of prosodic factors, particularly intonation, to the perception of foreign accent has seldom been the subject of studies in second language acquisition. In perception tests using low-pass filtered stimuli this study shows that a significant number of listeners is able to discriminate American English and German in stretches of speech 30 seconds or longer. The listeners are even more successful in direct pair comparisons, showing that the prosodic characteristics of American English and German are distinct enough to contribute to an obvious language-specific difference. The same tests are repeated using low-pass filtered stimuli with monotonous intonation. In this case all results are significantly worse. It can thus be claimed that intonation is clearly the most important prosodic factor in the perception of foreign accent. The relevance of intonation is also validated in a foreign accent rating task and a direct pair comparison using original foreign-accented American English utterances by native speakers of German and F0-generated and resynthesized versions in which the intonational errors are corrected. Finally, the study also attempts to give an impression of the respective shares of segmental and intonational aspects of foreign accent by comparing the ratings of fully synthesized versions of the speakers’ original utterances (no segmental foreign accent, but intonational foreign accent) and of F0-generated, “improved” versions (no intonational, but segmental foreign accent). It is shown that segmental aspects have a bigger influence on the perception of foreign accent.
