汉语文语转换系统地址映射算法的设计与实现

Design and Implementation of Mapping Address Algorithm in Chinese Text-to-Speech System

针对多样本文语转换系统中的语音合成实时性问题,提出了对合成系统语音库的改进策略和语音单元之间相似度的计算方法,在此基础上设计并实现了查找语音单元的地址映射算法.实验表明,地址映射算法和音库的重新组织有效地提高了合成系统的实时性.

In order to solve the real-time synthesis problem in a multi-sample text-to-speech system, the strategy of improving the structure of speech database is discussed and a method of calculating the similarities between two speech units is put forth. On the basis of these, a mapping address algorithm to locate the address of speech unit is brought up. The experimental results show that mapping address algorithm and reconstruction of speech database improve the real-time performance of text-to-speech system.
