Most current theories and models of second language speech perception are grounded in the notion that learners acquire speech sound categories in their target language. In this paper, this classic idea in speech perception is revisited, given that clear evidence for formation of such categories is lacking in previous research. To understand the debate on the nature of speech sound representations in a second language, an operational definition of "category" is presented, and the issues of categorical perception and current theories of second language learning are reviewed. Following this, behavioral and neuroimaging evidence for and against acquisition of categorical representations is described. Finally, recommendations for future work are discussed. The paper concludes with a recommendation for integration of behavioral and neuroimaging work and theory in this area.
目前大多数关于第二语言语音感知的理论和模型都是基于这样一种观念，即学习者在目标语中习得语音类别。在本文中，重新审视了这一在语音感知方面的经典观点，因为之前的研究中缺乏形成这种类别的明确证据。为了理解关于第二语言中语音表示的本质的争论，本文提出了“类别”的操作性定义，并回顾了范畴感知和第二语言学习的现有理论。接下来，描述了支持和反对获得范畴性表示的行为和神经影像学证据。最后，讨论了未来工作的建议。本文最后建议在这一领域整合行为和神经影像学工作和理论。
