Speech perception requires the decoding of complex acoustic patterns. According to most cognitive models of spoken word recognition, this complexity is dealt with before lexical access via a process of abstraction from the acoustic signal to pre-lexical categories. It is currently unclear how these categories are implemented in the auditory cortex. Recent advances in animal neurophysiology and human functional imaging have made it possible to investigate the processing of speech in terms of probabilistic cortical maps rather than simple cognitive subtraction, which will enable us to relate neurometric data more directly to behavioural studies. We suggest that integration of insights from cognitive science, neurophysiology and functional imaging is necessary for furthering our understanding of pre-lexical abstraction in the cortex.
语音感知需要对复杂的声学模式进行解码。根据大多数口语单词识别的认知模型，这种复杂性在词汇通达之前通过从声学信号到词汇前类别进行抽象的过程来处理。目前尚不清楚这些类别在听觉皮层中是如何实现的。动物神经生理学和人类功能成像的最新进展使得从概率性皮层图谱而非简单的认知减法角度来研究语音处理成为可能，这将使我们能够将神经测量数据更直接地与行为研究联系起来。我们认为，整合认知科学、神经生理学和功能成像的见解对于深化我们对皮层中词汇前抽象的理解是必要的。
