摘要
提出了一种LPC参数的M-L树形搜索多级矢量量化方案,其谱失真小于或接近1 dB,计算复杂度低,存储量小.计算机模拟表明,采用该方案对线谱对(LSPs)参数进行矢量量化,可提供透明质量的合成语音.
This paper presents a M - L tree - searched multi - stage vector quantization scheme for the LPC parameters which achieves spectral distortion lower than or close to ldB with low complexity and memory requirement. The computer simulation results show that it achieves transparent reconstructed speech when used for the quantization of LSPs parameters.
