Vowel deletion is a phonological process in which an unstressed /inverted e/ (schwa) vowel is deleted during pronunciation. In Experiment 1, vowel-deleted and vowel-reduced versions of two- and three-syllable words rated for pronunciation acceptability showed reduced acceptability for deleted vowel versions with a greater decrement for two-syllable words. Experiments 2 and 3 used vowel-intact and vowel-deleted productions preceded by themselves (repetition prime), their alternative production (variant prime), or a control (unrelated) prime. Lexical decisions to three-syllable vowel-intact and vowel-deleted targets, as well as to two-syllable vowel-intact targets, showed greater priming in the repetition conditions than in the variant conditions. Two-syllable vowel-deleted targets, however, showed comparable repetition and variant priming. The results are discussed in terms of lexical activation and representation of phonological variants. A model is offered in which activation based on similarity triggers utilization of phonological inferences only when required for successful recognition.
元音删除是一种音系过程，即在发音过程中，一个不重读的 /ə/（弱读音）元音被删除。在实验1中，对发音可接受性进行评级的双音节和三音节单词的元音删除版和元音弱化版显示，删除元音的版本可接受性降低，双音节单词的降幅更大。实验2和实验3使用了在自身（重复启动）、其替代发音（变体启动）或对照（无关）启动之前的元音完整和元音删除的发音。对三音节元音完整和元音删除目标以及双音节元音完整目标的词汇判断显示，重复条件下的启动效应比变体条件下更大。然而，双音节元音删除目标在重复和变体启动方面表现相当。从词汇激活和音系变体的表征方面对结果进行了讨论。提出了一个模型，其中基于相似性的激活仅在成功识别需要时触发音系推理的运用。
