我们描述了一个语音感知模型[基于视觉单词感知的交互激活模型（参见McClelland and Rumelhart， in press; Rumelhart and McClelland, in press）]，其中语音特征、音素和单词节点之间的兴奋性和抑制性相互作用用于解释语音感知中自下而上和自上而下过程相互作用的各个方面。给出了该模型的计算机仿真结果。输入到程序的是随着时间的推移而展开的不同语言特征的规范。激活与输入相一致的特征、音素、单词，填补缺失的规范，纠正细微的错误，使模拟形成的“感知”呈现出音位恢复和相关感知效应等现象。[NSF支持的工作。]
We describe a model of speech perception [based on the Interactive Activation Model of Visual Word Perception (cf. McClelland and Rumelhart, in press; Rumelhart and McClelland, in press)] in which excitatory and inhibitory interactions among nodes for phonetic features, phonemes, and words are used to account for aspects of the interaction of bottom‐up and top‐down processes in perception of speech. Results from a working computer simulation of this model are presented. Input to the program consists of specifications of distinctive features of speech as they unfold in time. Features, phonemes, and words consistent with the input are activated, missing specifications may be filled in, and slight errors may be corrected so that the “percept” formed by the simulation exhibits such phenomena as phonemic restoration and related perceptual effects.
