摘　　要：为了进一步提高汉语语音合成的自然度,通过对汉语语音合成技术的分析与对比,确定了以汉语音节作为拼接的合成基元,采用韵律匹配代价和韵律拼接代价的方法,进行合成基元的优化选取,实现了汉语语音合成的韵律建模及其韵律控制.采用直接拼接、过渡拼接和拟拼接,实现合成基元之间的拼接与平滑过渡.实验结果表明了汉语语音合成及其韵律控制方法的有效性.For further improving naturalness of Chinese speech synthesis, through analyzing and comparing on Chinese speech synthesis technology, a Chinese syllable has been determined as the concatenated and selected unit. Methods of prosodic matched cost and prosodic concatenated cost are applied for optimal selection of selected units from speech database, so Chinese prosodic model has been constituted for better Chinese prosodic control. Meanwhile, the direct concatenation, transition concatenation and imitating concatenation have been used to realize concatenation and smoothness transition between selected units. The experimental results show Chinese TTS and the proposed prosodic control algorithm to be available.
