The cross modal repetition priming paradigm was used to investigate how potential lexically ambiguous no-release variants are processed. In particular we focus on segmental regularities that affect the variant's frequency of occurrence (voicing of the critical segment) and phonological context in which the variant occurs (status of the following word-initial segment). Primes consisted of carrier words ending in a segment likely (voiced; e.g., BAND) or unlikely (voiceless; PLANT) to be produced in no-release form followed by a consonant or vowel onset context word. Each carrier word had an embedded lexical competitor (embedded word) formed by the segments prior to its final consonant (e.g., plan in plant). Productions of these embedded words (true embedded word) were also used as primes. Both true embedded words (Experiments Ia-Ic) and carrier words (Experiments 2a-2c) were used as visual targets.The results are discussed in terms of the contribution of probabilistic speech events to theories of spoken word recognition and lexical competition.
采用跨模态重复启动范式来研究潜在的词汇歧义性无释放变体是如何被处理的。具体而言，我们关注影响变体出现频率（关键音段的浊音化）的音段规律，以及变体出现的语音语境（后续单词首音段的状态）。启动刺激由以可能（浊音；如BAND）或不太可能（清音；PLANT）以无释放形式产生的音段结尾的载体词组成，后面跟着一个辅音或元音起始的语境词。每个载体词都有一个由其最后一个辅音之前的音段形成的嵌入式词汇竞争者（嵌入式词）（如plant中的plan）。这些嵌入式词（真正的嵌入式词）的发音也被用作启动刺激。真正的嵌入式词（实验Ia - Ic）和载体词（实验2a - 2c）都被用作视觉目标。根据概率性言语事件对口语单词识别理论和词汇竞争的贡献来讨论结果。
