    目前2.4kbps的混合激励线性预测 (MELP) 语音编码方法已经被确定为美国新的联邦语音编码标准.本文提出了一种改进的MELP语音编码方法,利用滤波器相似度和基于LPC系数分类的矢量量化技术,可以把MELP的码率降到1.7kbps以下,仍有较好的合成语音质量.(An Improved MELP Speech Coder)

    科大讯飞语音转文字源码是一个基于科大讯飞的语音转文字的例子源码,小编测试一下表示被着准确率惊呆了,之前小编用过其他的语音搜索类的工具,但是准确率总是不那么满意,用这个例子我试着读了杂志上的一段话,语速还略微快了一些,但是转换出来的文字只有两个字跟原文不一样,但是还是同音字。(IFLYTEK speech text source is a turn based on iFLYTEK speech text examples of the source code, test bit representation of the being accurate rate was shocked, before Xiaobian used other voice search tool, but the accuracy is always not so satisfactory, for this example I try to read a passage in the magazine, speed is slightly faster, but convert text only two words with the original text is not the same, but still homophones.)
