Authors propose a method for sudden noise reduction. This method first detects noisy part of the input signal, contaminated with sudden noise, using a nonlinear digital filter, named as a stationary-nonstationary separating filter, and then applies time-frequency domain masking only to the noisy parts in order to reduce the noise with minimum distortion. The voice model and the noise model are required to realize the time-frequency domain masking. The voice model is generated from both of training speech data and the part of the input signal, judged as a clean part without noise by the stationary-nonstationary separating filter. The noise model is generated from training noise data. These two models are used to calculate masking function. Computer simulations verify the high performance of the proposed method. |
