The key for improving the naturalness of the synthetic speech is to build a perfect prosodic model. 提高汉语合成语音的自然度的关键是要建立一个完善的汉语韵律模型。
Experimental results indicate that the approach is perceptually superior to the conventional SOLA method, thus improving the efficiency in low rate speech coding. 实验证明本方法对低采样率合成语音质量有显著改善，在低码率语音编码中可以有效提高编码效率。
