基于汉语节律特征描述的语音合成模型

A Study of Machine Speech Synthesis Based on Chinese Rhythms

汉语节律的合理使用能使合成语音表现出语篇的正确内涵和感情色彩。本文介绍了一种基于汉语节律特征描述的语音合成模型。本文首先介绍了汉语节律的停延、词重音、句重音、变调、调模等节律特征的分析和提取,详细描述了节律特征的各类情形,并阐述了基于汉语节律的语音合成算法模型,包括切词、标注、分析、定模、修正、输出的处理流程和合成语音声学参数序列{(h,l,s)}的生成。最后,给出了语音合成模型的实验结果与分析。

This paper analyzes and concludes the characteristics of Chinese rhythms, including the pauses, the accents of the words, the accents of the sentences, the inflections, the melody＇s modes of the Mandarin discourse. It describes the proposed arithmetic model of machine speech synthesis based on Chinese rhythms in detail The experiment shows that speech has perfect intention and emotion color in the proposed arithmetic model,and the speech synthesis quality is improved a lot.
