首先探讨了信号特性和非信号信息在语音感知中的相对作用。证据有力地表明，语音感知从来不是原始信号的无知识记录。这一结论不仅适用于“更高”层次的语言处理，也被认为适用于对基本语音刺激的感知。对有关生产的广泛事实的回顾突出了语音生产是自适应组织的事实。这种情况表明，该信号不编码发音或声学/听觉不变量，而是对听者语音处理系统中已有的多模态信息起到补充作用。因此，有人提出，语音信号不是包裹在“噪音”中的不变量，而是听者依赖的适应的产物，这种适应以原则和可解释的方式改变了语音模式。听者是否通过中间发音表征形成言语知觉？似乎有强有力的理论和方法上的理由来怀疑它们的存在。(C) 1996美国声学学会。
The relative roles played by signal properties and nonsignal information in speech perception are first examined. The evidence strongly suggests that phonetic percepts are never knowledge-innocent records of the raw signal. That conclusion is drawn not only about "higher" levels of language processing, but is seen to apply also to the perception of elementary phonetic stimuli. A review of a broad range of facts about production highlights the fact that speech production is adaptively organized. That circumstance suggests that the signal does not encode articulatory or acoustic/auditory invariants, but plays the role of supplementing the multimodal information already in place in the listener's speech processing system. It is accordingly proposed that phonetic signals are not invariants wrapped in "noise," but are products of listener-dependent adaptations that transform speech patterns in principled and, therefore, interpretable ways. Do listeners form speech percepts by way of intermediate articulatory representations? There seem to be strong both theoretical and methodological reasons to doubt that they do.
