Coding of speech at 8 kbit s using conjugate - structure algebraic - code - excited linear - predictive cs - acelp 使用共轭结构代数码激励线性预测的8kbit s语音编码
Focused search method is replaced by the pulse replacement procedure to optimize the search method of the algebraic codebook 对代数码本搜索方法的优化同样是通过改变搜索准则完成的。
Both of the optimized methods for lsp parameters and algebraic codebooks can provide the similar performance as the standard method with less search load 对分裂矢量量化码本搜索方式的优化和代数码本搜索方式的优化都在不明显降低合成语音质量的情况下有效地减少了运算量。
It adopts the structure of algebraic codebook and focused search of algebraic codebook to increase agility and randomicity , which decreases the complexity of this algorithm greatly 它是一种改进的码本激励线性预测算法,采用的是代数码本结构及聚焦搜索技术,提高了码本的灵活性和随机性,极大地降低了算法的复杂度。
Tetra - the new digital trunked communication system , specifies algebraic codebook excited linear prediction ( acelp ) , which is improved codebook excited linear prediction ( celp ) , as its speech codec . the bit rate of it is 4 . 567kbit / s 本文首先详细介绍了新一代数字集群通信系统tetra的语音编解码采用的编码速率4 . 567kbit s的代数码本激励线性预测( acelp )算法。
