以前的研究表明，单词的开头部分会激活发音相似的单词，这些单词会竞争识别能力。其他研究表明，被激活的发音相似的单词的数量会影响识别的速度和准确性。邻居较少的单词比邻居较多的单词处理得更快、更准确。在一项跟踪任务和一项词汇判断任务中，考察了单词开头部分的词汇竞争者数量的影响。较少邻居共享声母音素的目标单词比具有许多邻居共享声母音素的目标单词的反应更快。讨论了起始密度效应对口语识别模型的影响。
Previous research has suggested that the initial portion of a word activates similar sounding words that compete for recognition. Other research has shown that the number of similar sounding words that are activated influences the speed and accuracy of recognition. Words with few neighbors are processed more quickly and accurately than words with many neighbors. The influences of the number of lexical competitors in the initial part of the word were examined in a shadowing and a lexical-decision task. Target words with few neighbors that share the initial phoneme were responded to more quickly than target words with many neighbors that share the initial phoneme. The implications of onset-density effects for models of spoken-word recognition are discussed.
