在 VCV 无意义形式中（例如 /epsilondepsilon/，虽然 CV 过渡和 VC 过渡都可以单独感知，但 CV 过渡主导着塞音的识别。因此，问题出现了，VC 过渡在单词感知中发挥什么作用（如果有的话）？刺激物是双音节英语单词，其中中间辅音要么是塞音，要么是摩擦音（例如， “喂食”和“肉汁”）。每个单词都以三种方式构建：(1) VC 转换在任何位置、发音方式或两者上都与 CV 不兼容； (2)消除了VC转变，并用第一个元音的稳态部分代替了它的位置； (3)原词。特定单词的所有版本在持续时间、音调轮廓和幅度包络方面都是相同的。同时 可懂度测试显示这三种条件之间没有差异，来自配对比较偏好任务和无速度词汇决策任务的数据表明，不兼容的 VC 转换会阻碍单词感知，但缺乏 VC 转换却不会。然而，在单词刺激的快速词汇决策任务中，三个条件之间存在明显差异，但对于以类似方式构建的非单词刺激则没有。我们讨论使用 用于语音质量评估的词汇任务以及听众识别口语单词的可能过程。
In VCV nonsense forms (such as /epsilondepsilon/, while both the CV transition and the VC transition are perceptible in isolation, the CV transition dominates identification of the stop consonant. Thus, the question arises, what role, if any, do VC transitions play in word perception? Stimuli were two-syllable English words in which the medial consonant was either a stop or a fricative (e.g., "feeding" and "gravy"). Each word was constructed in three ways: (1) the VC transition was incompatible with the CV in either place, manner of articulation, or both; (2) the VC transition was eliminated and the steady-state portion of first vowel was substituted in its place; and (3) the original word. All versions of a particular word were identical with respect to duration, pitch contour, and amplitude envelope. While an intelligibility test revealed no differences among the three conditions, data from a paired comparison preference task and an unspeeded lexical decision task indicated that incompatible VC transitions hindered word perception, but lack of VC transitions did not. However, there were clear differences among the three conditions in the speeded lexical decision task for word stimuli, but not for nonword stimuli that were constructed in an analogous fashion. We discuss the use of lexical tasks for speech quality assessment and possible processes by which listeners recognize spoken words.
