This article reports the results of two experiments investigating the combined role of vowel length and length of fricative voicing in the identification, by Brazilians, of minimal pairs such as casa /z/ – caca /s/ produced by speakers of Spanish (L1). In Experiment 1, stimuli were manipulated so that length of voicing in the fricative was tested in two levels (100% or 0% of voicing) and vowel length was tested in four levels (25%, 50%, 75% and 100% of the length of the total vowel). In Experiment 2, voicing length was tested in three levels (25%, 50% and 75% of voicing), combined with the four levels of vowel length (25%, 50%, 75% and 100% of the length of the total vowel). Both experiments were run on TP Software (Rauber et al. 2012), and forty Brazilian listeners with no experience with Spanish took part in both tasks. The results show an interaction between the two cues, especially in the stimuli with no full voicing in the fricative. These findings provide additional evidence to the gradient status of speech in production and perceptual phenomena (Albano 2001; Albano 2012; Perozzo 2017), besides shedding light on the teaching of Brazilian Portuguese as an Additional Language.

聆听巴西葡萄牙语中的重音讲话：关于摩擦音和元音持续时间在识别母语为L1的西班牙语的/ s / – / z /最小对中的作用

本文报告了两个实验的结果，这两个实验研究了元音长度和摩擦音长度在巴西人识别最小的音对（例如讲西班牙语的母语者（ca）/ ca /​​/ caca / s /）中的结合作用。在实验1中，对刺激进行了控制，以便以两个级别（100％或0％的发声）测试摩擦音中的发声长度，并以四个级别（25％，50％，75％和100％的发声率）测试元音长度。元音的总长度）。在实验2中，测试了三个水平的发音长度（分别为25％，50％和75％），并结合了四个水平的元音长度（分别为总长度的25％，50％，75％和100％）元音）。两项实验均在TP Software上运行（Rauber等人，2012年），有40名没有西班牙语经验的巴西听众参与了这两项任务。结果显示两个提示之间的相互作用，特别是在刺激中，摩擦音没有完全发声。这些发现除了为巴西葡萄牙语作为一种额外语言的教学提供了亮点之外，还为语音在生产和感知现象中的梯度状态提供了额外的证据（Albano 2001； Albano 2012； Perozzo 2017）。
