摘要
韵律结构的预测 ,主要包括短语的自动切分和重音的等级分布两个大的方面。本文在概述汉语韵律结构的基础上 ,根据从自然话语中获得的韵律结构与句法结构和词性的关系 ,用一种新的方法 ,通过文本分析 ,全面地预测韵律边界的位置分布及其等级差异 ,并进一步预测重音的位置分布及其等级差异。
It is especially necessary to generate prosody automatically in a Chinese TTS system. The main task is to segment the Chinese character sequence into proper speech units and organize them as a prosodic hierarchy. This goal can be satisfied by inserting different strength of breaks and assigning certain degree of stresses within a sentence. This paper will discuss how to predict the location and strength of break and stress based on syntactic and lexical information extracted from text analysis. Our attention will be paid to following aspects: (1)a brief description on Chinese prosody; (2)text analysis; (3)predictive-tree building; (4)break index prediction; (5)stress index prediction.
