在已知的对分段感知起作用的语境因素中，有演讲产生的速度和项目的词汇状态，也就是说，它是否是语言中有意义的单词。在一系列关于单词首字母/b/ - /p/发音区分的实验中，我们研究了这些因素在语音处理过程中的作用条件。结果表明，在快速反应的指导下，在一些试验中，听者可以忽略单词中稍后出现的一些指定频率和词汇状态的上下文信息。然而，重要的是，他们不能完全忽略说话速度。虽然他们只能根据单词的开头部分做出决定，但当他们这样做时，他们会把这个单词当作一个物理上很短的单词——也就是说，好像没有后来发生的信息说明一个较慢的速度。这表明听者在识别辅音的发声值时总是会考虑语速，但准确地说，在单词中使用哪些信息来指定语速可能会因任务需求而异。
Among the contextual factors known to play a role in segmental perception are the rate at which the speech was produced and the lexical status of the item, that is, whether it is a meaningful word of the language. In a series of experiments on the word-initial/b/—/p/voicing distinction, we investigated the conditions under which these factors operate during speech processing. The results indicated that under instructions of speeded responding, listeners could, on some trials, ignore some later occurring contextual information within the word that specified rate and lexical status. Importantly, however, they could not ignore speaking rate entirely. Although they could base their decision on only the early portion of the word, when doing so they treated the word as if it were physically short—that is to say, as if there were no later occurring information specifying a slower rate. This suggests that listeners always take account of rate when identifying the voicing value of a consonant, but precisely which information within the word is used to specify rate can vary with task demands.
