摘要
针对汉语焦点的特性,设计了接近自然语流风格的实验语料。通过对语料的分析,运用CART技术,建立了焦点的韵律模型。在语音合成阶段,使用韵律模型生成语音的韵律参数,结合Straight算法,实现了语音焦点的合成。对合成效果的评测表明,该方法能够合成自然度很高的语音焦点。
Experimental speech materials close to nature speech situations is designed according to the features of focus in Mandarin Chinese. After analysis of those speech materials, a prosodic model of focus is built using CART technology. During speech synthesis,the focused speech is synthesized to meet the prosody features predicted by this model using straight algorithm. The result of evaluation shows that this method can produce high-quality focused speech.
