从噪声的背景中提取语言信息,是在噪声环境下进行语言通讯所迫切需要解决的问题。在DJS-131电子计算机构成的语言信号处理系统中,应用数字信号处理的方法如频谱减方法、自相关方法和线性滤波方法对含噪语言进行处理,取得了一定的效果。频谱减方法是利用快速付里叶变换将含噪语言与噪声的功率谱相减的处理方法,为了改进处理效果又采用了 Extracting language information from the background of noises is an urgent problem that needs to be solved in the language communication under noisy environment. DJS-131 computer language signal processing system, the application of digital signal processing methods such as spectral subtraction method, the autocorrelation method and linear filtering method for noisy speech processing, and achieved some results. Spectral subtraction method is the use of fast Fourier transform to the noisy speech and noise power spectrum subtraction processing method, in order to improve the processing effect has adopted
