语音处理的功能神经解剖学一直很难表征。进展的一个主要障碍是在映射语音相关处理系统时未能考虑任务效果。我们总结了一种解决这种情况的语音处理双流模型。在该模型中，腹侧流处理语音信号以供理解，背侧流将声学语音信号映射到顶叶和额叶发音网络。该模型假设腹侧流主要是双边组织的，尽管左半球和右半球系统之间存在重要的计算差异，而背侧流则强烈地由左半球主导。
The functional neuroanatomy of speech processing has been difficult to characterize. One major impediment to progress has been the failure to consider task effects when mapping speech-related processing systems. We summarize a dual-stream model of speech processing that addresses this situation. In this model, a ventral stream processes speech signals for comprehension, and a dorsal stream maps acoustic speech signals to parietal and frontal-lobe articulatory networks. The model assumes that the ventral stream is largely bilaterally organized, although there are important computational differences between the left- and right-hemisphere systems, whereas the dorsal stream is strongly left-hemisphere-dominant.
