论文摘要
本文研究了不同语音质量的激发中发生的差异。它的目标是两个方面。首先，分析了同一扬声器说出的三种语音质量（模态，柔软和响亮）的大型语料库，并观察到从激发中提取的特征上的显着差异。其次，从分析得出的修改规则用于构建一种语音质量转换系统，该系统应用于基于HMM的语音综合的后处理。该系统被证明可以有效地实现转换，同时保持交付的质量。
This paper investigates the differences occuring in the excitation for different voice qualities. Its goal is two-fold. First a large corpus containing three voice qualities (modal, soft and loud) uttered by the same speaker is analyzed and significant differences in characteristics extracted from the excitation are observed. Secondly rules of modification derived from the analysis are used to build a voice quality transformation system applied as a post-process to HMM-based speech synthesis. The system is shown to effectively achieve the transformations while maintaining the delivered quality.
