研究了说话者声音在口语单词识别中的一次又一次的变化对知觉的影响。一系列使用知觉识别和命名任务的实验结果表明，当试验保持不变时，知觉表现会下降。此外，说话者变异性对词汇识别的影响比词频和词汇结构的影响更强，对任务的依赖性更小。可能的假设有关的性质的过程引起这些影响进行了讨论，特别注意的想法，即处理有关的讲话者的声音的信息是密切相关的早期感知过程中提取的语音信号的声学语音信息。
The perceptual consequences of trial-to-trial changes in the voice of the talker on spoken word recognition were examined. The results from a series of experiments using perceptual identification and naming tasks demonstrated that perceptual performance decreases when the trial remains the same. In addition, the effects of talker variability on word recognition appeared to be more robust and less dependent on task than the effects of word frequency and lexical structure. Possible hypotheses regarding the nature of the processes giving rise to these effects are discussed, with particular attention to the idea that the processing of information about the talker''s voice is intimately related to early perceptual processes that extract acoustic-phonetic information from the speech signal.
