Spoken language comprehension requires the coordination of different subprocesses in time. After the initial acoustic analysis the system has to extract segmental information such as phonemes, syntactic elements and lexical-semantic elements as well as suprasegmental information such as accentuation and intonational phrases, i.e., prosody. According to the dynamic dual pathway model of auditory language comprehension syntactic and semantic information are primarily processed in a left hemispheric temporo-frontal pathway including separate circuits for syntactic and semantic information whereas sentence level prosody is processed in a right hemispheric temporo-frontal pathway. The relative lateralization of these functions occurs as a result of stimulus properties and processing demands. The observed interaction between syntactic and prosodic information during auditory sentence comprehension is attributed to dynamic interactions between the two hemispheres.
口语理解需要不同子过程在时间上的协调。在初始声学分析之后，系统必须提取诸如音素、句法元素和词汇语义元素等片段信息，以及诸如重音和语调短语等超片段信息，即韵律。根据听觉语言理解的动态双通路模型，句法和语义信息主要在左半球颞额通路中处理，该通路包括用于句法和语义信息的独立回路，而句子层面的韵律则在右半球颞额通路中处理。这些功能的相对偏侧化是由刺激特性和处理需求导致的。在听觉句子理解过程中观察到的句法和韵律信息之间的相互作用归因于两个半球之间的动态相互作用。
