在[Levelt，W.J.M.，Roelofs，A.，Meyer，A.S.(1999)]提出的言语产生模型中。言语产生中的词汇通达理论。行为和脑科学，22，第1-75页]，音节在语音和语音编码的界面上起着至关重要的作用。在这个界面上，抽象的音节被翻译成音节。这一翻译过程被认为是由一个所谓的心理音节来调节的。不是在线构建每个音节的运动程序，而是假设心理音程表为发音者提供预先汇编的手势分数。为了找到这样一个储存库的证据，我们研究了音节频率效应：如果心理音节由与音节对应的可提取表征组成，那么提取过程应该对频率差异敏感。在使用符号位置联想学习任务的一系列实验中，我们测试了高频音节是否比低频音节提取和产生得更快。我们发现单音节假词和双音节假词存在显著的音节频率效应，其中第一个音节进行频率操纵，而第二个音节没有影响。讨论了这些结果对语音编码和语音编码交界处的词形编码理论的启示，特别是关于Levelt等人的言语产生模型中心理音节的通达机制。(C)2005 Elsevier B.V.保留所有权利。
In the speech production model proposed by [Levelt, W. J. M., Roelofs, A., Meyer, A. S. (1999). A theory of lexical access in speech production. Behavioral and Brain Sciences, 22, pp. 1-75.], syllables play a crucial role at the interface of phonological and phonetic encoding. At this interface, abstract phonological syllables are translated into phonetic syllables. It is assumed that this translation process is mediated by a so-called Mental Syllabary. Rather than constructing, the motor programs for each syllable on-line, the mental syllabary is hypothesized to provide pre-compiled gestural scores for the articulators. In order to find evidence for such a repository, we investigated syllable-frequency effects: If the mental syllabary consists of retrievable representations corresponding to syllables, then the retrieval process should be sensitive to frequency differences. In a series of experiments using a symbol-position association learning task, we tested whether high-frequency syllables are retrieved and produced faster compared to low-frequency syllables. We found significant syllable frequency effects with monosyllabic pseudo-words and disyllabic pseudo-words in which the first syllable bore the frequency manipulation; no effect was found when the frequency manipulation was on the second syllable. The implications of these results for the theory of word form encoding at the interface of phonological and phonetic encoding; especially with respect to the access mechanisms to the mental syllabary in the speech production model by (Levelt et aL) are discussed.
