Can native listeners rapidly adapt to suprasegmental mispronunciations in foreign-accented speech? To address this question, an exposure-test paradigm was used to test whether Dutch listeners can improve their understanding of non-canonical lexical stress in Hungarian-accented Dutch. During exposure, one group of listeners heard a Dutch story with only initially stressed words, whereas another group also heard 28 words with canonical second-syllable stress (e.g., EEKhorn, "squirrel" was replaced by koNIJN "rabbit"; capitals indicate stress). The 28 words, however, were non-canonically marked by the Hungarian speaker with high pitch and amplitude on the initial syllable, both of which are stress cues in Dutch. After exposure, listeners' eye movements were tracked to Dutch target-competitor pairs with segmental overlap but different stress patterns, while they listened to new words from the same Hungarian speaker (e.g., HERsens, herSTEL, "brain," "recovery"). Listeners who had previously heard non-canonically produced words distinguished target-competitor pairs better than listeners who had only been exposed to Hungarian accent with canonical forms of lexical stress. Even a short exposure thus allows listeners to tune into speaker-specific realizations of words' suprasegmental make-up, and use this information for word recognition.
母语为荷兰语的人能否快速适应带有外国口音的语音中超音段的发音错误？为了回答这个问题，我们使用了一种暴露测试范式来检验荷兰人是否能够提高对带匈牙利口音的荷兰语中非典型词重音的理解。在暴露阶段，一组听众只听重音在词首的荷兰语故事，而另一组听众还听了 28 个重音在第二音节的词（如，EEKhorn，“松鼠”变成了 koNIJN“兔子”；大写表示重音）。然而，这些词被匈牙利语说话者用高的音高和幅度标记为非典型重音，这两种音高和幅度都是荷兰语中的重音线索。暴露阶段结束后，听众在听同一个匈牙利语说话者的新单词（如，HERsens，herSTEL，“大脑”，“恢复”）时，眼睛追踪到带有音段重叠但重音模式不同的荷兰语目标竞争词对。与只接触过带有典型词重音的匈牙利口音的听众相比，之前听过非典型发音词的听众能更好地区分目标竞争词对。即使是短暂的暴露，也能让听众调整到说话者特定的超音段组成的实现方式，并将这些信息用于单词识别。
