| Abstract(in English) | Spectral subtraction method, requiring about the same computation as high-speed convolution, suppresses stationary noise from speech by subtracting the spectral noise bias calculated during nonspeech activity. In this paper, in order to reduce the computational complexity and over estimatimation of noise, speech enhancement method using spectral subtraction and sub-band decomposition is proposed. |
