在本研究中，西班牙-英语双语者的浊音和不浊音停顿（a /b/-/p/连续体，包括前置浊音、不浊音和不浊音送气标记）的感知界限被受试者是否“被引导相信”他们正在分类西班牙语或英语发音而调节。在实验1中，西班牙语-英语双语者和初级第二语言西班牙语学习者在两个实验阶段（西班牙语模式和英语模式）中标记相同的声学连续体，发现两组都表现出语言特定的感知边界（或会话效应）。在实验二中，不同熟练程度的早期双语者和晚期第二语言学习者参加了一个单独的会话，在这个会话中，他们以随机的顺序标记旨在启动西班牙语或英语语言模式的非单词。早期双语者和相对熟练的第二语言学习者，而不是不熟练的学习者，即使在快速、随机的模式切换条件下，也表现出特定模式的知觉归一化标准。与类似的实验一样，这里报告的实验表明，双语者在处理语音时能够利用语言特定的感知过程（或规范），这需要在他们的声音系统之间进行一定程度的分离。
In the present study, Spanish-English bilinguals’ perceptual boundaries between voiced and voiceless stops (a /b/-/p/ continuum including pre-voiced, voiceless unaspirated, and voiceless aspirated tokens) are shown to be modulated by whether participants are “led to believe” they are classifying Spanish or English sounds. In Experiment 1, simultaneous Spanish-English bilinguals and beginner second-language learners of Spanish labeled the same acoustic continuum in two experimental sessions (Spanish mode, English mode), and both groups were found to display language-specific perceptual boundaries (or session effects). In Experiment 2, early bilinguals and late second-language learners of various levels of proficiency participated in a single session in which, in random order, they labeled nonwords that were designed to prime either Spanish or English language modes. Early bilinguals and relatively proficient second-language learners, but not less proficient learners, displayed mode-specific perceptual normalization criteria even in conditions of rapid, random mode switching. Along with similar ones, the experiments reported here demonstrate that bilinguals are able to exploit language-specific perceptual processes (or norms) when processing speech sounds, which entails some degree of separation between their sound systems.
