Historically, auditory research has focused predominately upon how relatively simple acoustic signals are represented in the neuronal responses of the auditory periphery. However, in order to understand the neurophysiology underlying speech perception, the ultimate objective is to discover how speech sounds are represented in the central auditory system and to relate that representation to the perception of speech as a meaningful acoustic signal. This paper reviews three areas that pertain to the central auditory representation of speech: (1) the differences in neural representation of speech sounds at different levels of the auditory system; (2) the relation between the representation of sound in the auditory pathway and the perception/misperception of speech, and (3) the training-related plasticity of speech sound neural representation and speech perception.
从历史上看，听觉研究主要集中在相对简单的声学信号如何在听觉外周的神经元反应中得到表征。然而，为了理解语音感知背后的神经生理学，最终目标是发现语音在中枢听觉系统中是如何被表征的，并将这种表征与作为有意义声学信号的语音感知联系起来。本文综述了与语音中枢听觉表征相关的三个领域：（1）听觉系统不同层次上语音的神经表征差异；（2）听觉通路中声音表征与语音感知/误感知之间的关系；以及（3）与训练相关的语音神经表征和语音感知的可塑性。
