摘　　要：将经典语音多带激励(MBE)算法应用于量子领域,提出经典信息与量子信息的对应关系,并给出相应的信息测度方法.对量子语音MBE的编解码算法用C语言进行仿真实验,结果证明,语音分解与合成前后的波形相近,用PESQ软件客观测试语音,MOS分数为3.337.Multi-band excitation （MBE） algorithm in classical communication is applied to quantum communication. The corresponding relation between classical information and quantum information is proposed, and the quantum measure-ment of information is presented. Simulations of quantum MBE algorithm by C language programming demonstrate that the wave of synthesized speech is similar to the original one. An MOS score of 3.337 is obtained from the Perceptual Evaluation of Speech Quality software.
