In this paper, the speech enhancement with a linear prediction error filter (LPEF) based on 4th order cumulant is proposed to reduce the non-stationary noise which is suddenly generated by hitting an object. The linear predictor converges such that the output of the linear predictor becomes the component with high kurtosis. The non-stationary noise is non-Gaussian with high kurtosis, on the other hand speech has low kurtosis. Thus, the linear predictor can estimate only the non-stationary noise. However, it is difficult for the LPEF based on a forward linear prediction to reduce the non-stationary noise, because the noise component is not included in the tap inputs when non-stationary noise is generated. Therefore, the backward linear prediction is used as the LPEF. |
