摘　　要：Based on the results of the acoustic research on Mandarin, two novel algorithms using the spectral information in speech processing of cochlear implants are purposed and certified effectively by the spectral information of tonal language in acoustic simulation experiments. We bring forward novel algorithms conveying the spectral information based on the choices of the frequency bands. These new algorithms can not only improve the speech recognition ability of cochlear implant users in the noisy environments but also reduce the complexity of computing and the memory occupied, and make it more suitable to be carried out in clinical practice.基于关于官员的声学的研究的结果，二个新奇算法用光谱在 cochJegr 的语音处理的信息植入是 purposed 并且有效地证明由光谱在声学的模拟实验的音调的语言的信息。我们带给 fonvard 传送的小说算法光谱信息基于频率乐队的选择。这些新算法不能仅仅改进语音识别能力耳蜗在吵闹的环境植入用户而且减少占据的计算和存储器的复杂性，并且使在临床的实践被执行更合适。
