汉语文语转换系统的语音规则和声学参数

利用瑞典皇家理工学院（KTH）语言通讯和音乐声学系Carlson和Granstrom设计的多语种文语转换系统,进行了汉语文语转换研究。对汉语文语转换用的基本语音规则和声学参数做了分析、设计和调试,特别对轻声、儿化和变调进行了研究。

Acoustic parameters and phonological rules of a text-to-speech system for Chinese

A multi-language text-to-speech system developed by Carlson and Granstrom was used to do text-to-speech conversion for Chinese. Both phonological rules and scoustic parameters are refined. The light tone and tone modification rules and er-coloured final rules are introduced. It is shown that to shorten duration is the most important feature for light tone syllables, and the principle of that the main vowel in the final should be pronounced with retroflex vowel /er/ simultaneously can be used for synthesizing er-coloured finals.
