在人类的语言交流中，语言事件，如各个音段，声调，韵律边界等都是信息传递的载体，所有的这些语言事件都为人类的语言交流起着不可或缺的作用。一直以来，语言学家通过听觉感知等一些方法来研究各个语言事件在交流中所起到的作用，而在本文我们提出了用互信息的功能负载的方法来度量每个语言事件所包含的信息量。这篇文章主要以韵律的层级结构为研究对象，深入分析了不同韵律层级的作用，并与以前音位的信息量作了初步的对比，结果表明边界信息在语言交流中所起到的作用远大于各个独立音段，在韵律边界层级结构中，层级越高，边界所起的作用越明显，如韵律短语边界所含的信息量大于韵律词语边界所含的信息量。本文的研究结果在语音科学，语音识别，语音合成等领域具有一定的指导意义。 -In the human language exchange, language events, such as various sound, tone, rhythm boundaries are the carrier of the transmission of information, all of these language events are human verbal communication plays an indispensable role. , Linguists auditory perception, such as some of the ways to study the role played by each language event in the exchange, in this paper, we propose a with functional load mutual information method to measure each language event information contained in amount. This article is mainly rhythm hierarchy for the study, in-depth analysis of the role of different levels of rhythm and made a preliminary comparison with the previous phoneme amount of information, the results show that the role played by the boundary information in the verbal communication ambitious individual sound segments in the the prosodic boundary layer stage structure, the higher the level, the role played by the boundaries of the more obvious, such as the amount of information contained
