多年来，人们一直认为，早期的语言经验对识别和辨别塞音的感知能力产生了深刻而持久的影响。它也已得出结论，选择性修改的感知塞辅音不能在实验室中完成简单的歧视培训技术容易和快速。在这篇文章中，我们报告的三个实验的结果，探讨了一个三路语音对比的看法天真的单语英语发言者。实验室训练程序是用一台小型计算机在实时环境中进行的，以检查在语音起始时间上不同的浊音、不送气和不送气塞音的感知。三个感知类别后，大多数受试者只有几分钟的曝光，以新颖的对比。随后的知觉测试显示，可靠的和一致的标签和类的歧视功能的所有三个发声类别，即使其中一个对比是不是在英语中的语音独特的。本研究的结果表明，成年人在塞音分类中使用的感知机制可以在短时间内通过简单的实验室技术容易地进行修改。
For many years there has been a consensus that early linguistic experience exerts a profound and often permanent effect on the perceptual abilities underlying the identification and discrimination of stop consonants. It has also been concluded that selective modification of the perception of stop consonants cannot be accomplished easily and quickly in the laboratory with simple discrimination training techniques. In the present article we report the results of three experiments that examined the perception of a three-way voicing contrast by naive monolingual speakers of English. Laboratory training procedures were implemented with a small computer in a real-time environment to examine the perception of voiced, voiceless unaspirated, and voiceless aspirated stops differing in voice onset time. Three perceptual categories were present for most subjects after only a few minutes of exposure to the novel contrast. Subsequent perceptual tests revealed reliable and consistent labeling and categorical-like discrimination functions for all three voicing categories, even though one of the contrasts is not phonologically distinctive in English. The present results demonstrate that the perceptual mechanisms used by adults in categorizing stop consonants can be modified easily with simple laboratory techniques in a short period of time.
