The perception of stress is highly influenced by listeners' native language. In this research, the authors examined the effect of intonation and talker variability (here: phonetic variability) in the discrimination of Spanish lexical stress contrasts by native Spanish (N = 17), German (N = 21), and French (N = 27) listeners. Participants listened to 216 trials containing three Spanish disyllabic words, where one word carried a different lexical stress to the others. The listeners' task was to identify the deviant word in each trial (Odd-One-Out task). The words in the trials were produced by either the same talker or by two different talkers, and carried the same or varying intonation patterns. The German listeners' performance was lower compared to the Spanish listeners but higher than that of the French listeners. French listeners performed above chance level with and without talker variability, and performed at chance level when intonation variability was introduced. Results are discussed in the context of the stress "deafness" hypothesis.
压力的感知受到听众母语的极大影响。在这项研究中，作者通过母语为西班牙语（N=17）、德语（N=21）和法语（N=27）的听众，考察了语调以及说话人变异性（此处：语音变异性）对西班牙语重音对比的辨别效果。参与者聆听了包含三个西班牙语双音节词的 216 个试验，其中一个词与其他词的重音不同。参与者的任务是在每个试验中识别出异常的单词（One-Out 任务）。试验中的单词由同一个说话人或两个不同的说话人说出，并带有相同或不同的语调模式。与西班牙语听众相比，德语听众的表现较差，但优于法语听众。法语听众在有和没有说话人变异性的情况下表现都高于随机水平，而在引入语调变异性时则表现为随机水平。结果在重音“失聪”假说的背景下进行了讨论。
