Four experiments investigated acoustic-phonetic similarity in the mapping process between the speech signal and lexical representations (vertical similarity). Auditory stimuli were used where ambiguous initial phonemes rendered a phoneme sequence lexically ambiguous (perceptual-lexical ambiguities). A cross-modal priming paradigm (Experiments 1, 2, and 3) showed facilitation for targets related to both interpretations of the ambiguities, indicating multiple activation. Experiment 4 investigated individual differences and the role of sentence context in vertical similarity mapping. The results support a model where spoken word recognition proceeds via goodness-of-fit mapping between speech and lexical representations that is not influenced by sentence context.
四项实验研究了语音信号与词汇表征之间映射过程中的声学语音相似性（纵向相似性）。使用了听觉刺激，其中模糊的初始音素使音素序列在词汇上具有歧义（感知-词汇歧义）。一种跨模态启动范式（实验1、2和3）显示，与歧义的两种解释相关的目标都得到了促进，这表明存在多重激活。实验4研究了个体差异以及句子语境在纵向相似性映射中的作用。结果支持了一种模型，即口语单词识别是通过语音与词汇表征之间的拟合度映射进行的，且不受句子语境的影响。
