谱减法是利用噪声的统计平稳性以及加性噪声与语音不相关的特点而提出来的。即让有语音期间噪声幅度谱的期望值与无语音间隙噪声的幅度谱的期望值相等。(Spectral subtraction method is the use of stationary noise statistics and the additive noise and speech characteristics not related to the initiative. During that speech so that the expected value of noise amplitude spectrum and noise-free audio gap equal to the expected amplitude spectrum.)
