由于声道生理的个体差异，不同的人发出的语音在声学上是不同的。语言中“相同”单词的这种声学变化给语言学家和工程师提出了一个实际问题，也是语音感知研究中的一个理论问题。本章回顾了一些实用的元音规范化方法，并讨论了听众在面对说话者变化时可能用于完成语音识别的感知过程，并概述了说话者规范化和语音感知的皮层组织。本章回顾的证据表明，听觉处理的一些方面有助于消除言语感知过程中的说话者差异-在听觉频谱编码中;相反，在听觉参考框架中的编码似乎适用于词汇处理开始之前。
Speech produced by different people varies acoustically because of individual differences in vocal tract physiology. This acoustic variation in the “same” words of language presents a practical problem for linguists and engineers, as well as a theoretical problem in the study of speech perception. This chapter reviews some practical vowel‐normalization methods and discusses the perceptual processes that listeners may use to accomplish speech recognition in the face of talker variation, with a general overview of cortical organization for talker normalization and speech perception. The chapter reviews evidence that there are aspects of auditory processing that help remove talker differences during speech perception ‐ in auditory spectral encoding; and in contrast coding in an auditory frame of reference that seems to apply before lexical processing begins.
