Corpus-Based speech synthesis approach has been applied in many state-of-art speech synthesis systems because it can produce synthetic voice of high naturalness .

基于大语料库的语音合成方法，由于能够产生高自然度的 合成 语音，成为目前应用较多的语音合成方法。

In verification stage the synthesis results are simulated by using MATLAB software . The simulation results show that synthetic voice greatly represent the amplitude-frequency characteristics of voice samples and obtained high quality . And the algorithm complexity analysis also proves that the improved algorithm meets requirements .

利用MATLAB软件对合成结果进行仿真，结果表明， 合成 语音很好地体现了语音样本的幅频特性，具有较高的 合成质量；通过算法复杂度分析，证明本文所采用的改进算法是符合要求的。

The synthetic application of three tests can estimate the hoarseness more correctly . Before and after the treatment voice sample were collected and analyzed with USSA ( Univeral Signal Spectrum Analys ) and quality was measured objectively .

三者的 综合应用，能更好地评价嗓音质量。应用 嗓音分析系统对治疗前后的 声样作声学分析，获取有关声谱图，并对嗓音质量作客观评估。

Address this issue we have proposed a three vector quantization method . The rate of MELP can be dropped to around 2.1 kbps and there are still good quality of synthetic voice .

针对于这一问题，我们提出了三级矢量量化的方法，从而可以把MELP的码率降到2.1kbps左右，仍有较好的 合成 语音质量。

By using these coding technologies the algorithm at the 900 bit / s rate has a relatively satisfied synthetic voice and is realized in MATLAB .

通过采用上述编码技术，该算法在900bit/s的速率上获得了比较满意的 合成 语音，并在MATLAB中得到实现。
