在随意的言语中，单词可以有多种发音方式。对这些发音变体出现频率的语料库分析（例如，）表明，通常，一种发音变体往往占主导地位；这就提出了一个问题：变异识别是否与暴露频率一致。我们在包含四种语音上下文之一的单词中探讨了这个问题，每种语音上下文都有利于单词中间/t/的四种表面实现之一：[t]、[ʔ]、[ɾ]或删除的变体。针对生产实验中的一组单词，估计了所有四种上下文中四种实现的频率。然后在词汇决策实验中测量对所有发音变体的识别。总体而言，数据表明听众对变体频率很敏感：单词分类率与生产频率密切相关。例外的是[t]实现（即单词的规范发音），这一发现证实了文献中的其他结果，并表明除了暴露频率之外的因素也会影响单词识别。
Words can be pronounced in multiple ways in casual speech. Corpus analyses of the frequency with which these pronunciation variants occur (e.g.,) show that typically, one pronunciation variant tends to predominate; this raises the question of whether variant recognition is aligned with exposure frequency. We explored this issue in words containing one of four phonological contexts, each of which favors one of four surface realizations of word-medial /t/: [t], [ʔ], [ɾ], or a deleted variant. The frequencies of the four realizations in all four contexts were estimated for a set of words in a production experiment. Recognition of all pronunciation variants was then measured in a lexical decision experiment. Overall, the data suggest that listeners are sensitive to variant frequency: Word classification rates closely paralleled production frequency. The exceptions to this were [t] realizations (i.e., canonical pronunciations of the words), a finding which confirms other results in the literature and indicates that factors other than exposure frequency affect word recognition.
