如何识别口语单词的发音变体（中心->“senna”或“sennah”）的一种解释是，亚词汇过程使用关于相同语音环境中的变化的信息来恢复预期的片段[Gaskell，G.，& Marslen-Wilson，W. D.（1998年）。言语知觉中的音系推理机制。Journal of Experimental Psychology：Human Perception and Performance，24，380-396.本研究测试的限制，这音韵推理帐户检查如何听众的过程中，第一次一个新学到的单词的发音变体。这种变体的识别应该发生，只要它拥有合法化的变化的语音结构。实验1和2确定了一个语音环境，满足必要的条件，语音推理机制是可操作的。使用单词学习的范例，实验3至5表明，推理本身是不够的，但可以促进它的泛化，而导致泛化的一个条件是有意义的暴露在一个无意中听到的对话中的变体，表明词汇处理是必要的变体识别。
One account of how pronunciation variants of spoken words (center-> “senner” or “sennah”) are recognized is that sublexical processes use information about variation in the same phonological environments to recover the intended segments [Gaskell, G., & Marslen-Wilson, W. D. (1998). Mechanisms of phonological inference in speech perception. Journal of Experimental Psychology: Human Perception and Performance, 24, 380–396]. The present study tests the limits of this phonological inference account by examining how listeners process for the first time a pronunciation variant of a newly learned word. Recognition of such a variant should occur as long as it possesses the phonological structure that legitimizes the variation. Experiments 1 and 2 identify a phonological environment that satisfies the conditions necessary for a phonological inference mechanism to be operational. Using a word-learning paradigm, Experiments 3 through 5 show that inference alone is not sufficient for generalization but could facilitate it, and that one condition that leads to generalization is meaningful exposure to the variant in an overheard conversation, demonstrating that lexical processing is necessary for variant recognition.
