摘要
近年来的语音编码算法研究集中在参数编码以及混合编码方式,参数编码和混合编码是基于语音产生模型的编码方法,而线性预测分析技术则是这2种编码算法的基础。讨论LPC线性预测分析技术,主要分析了LPC 10算法的编解码过程,并且通过Matlab仿真,实现了一个简化的LPC 10声码器模型,通过对比重建语音和原始语音研究分析该算法的优缺点。
In recent years,the research of the speech coding has been focussing on the speech parameter coding and mixed coding, the two coding methods are based on the Speech Generation Model. The linear predictive analysis is the basic of these two coding algorithm. This paper discusses the LPC technology, mainly analyzes the coding and decoding process of the LPC- 10. We utilize the Matlab software simulating technology to realize a simple LPC - 10 Vocoder model, analyzed the advantage and drawback of LPC- 10 according to the contrast of the rebuilding voice and original voice.
