| 摘要: |
| 对被污染的语音信号的去噪进行了讨论与分析, 应用异于DJ硬、软门限的新门限法对语音信号进行了去噪的仿真计算, 结果确实优于DJ软、硬门限的去噪法。 |

| Abstract: |
| A new method for speech denoising is presented which uses a new threshold different from DJ's thresholds. Preliminary computer simulations were performed on speech signals and resulted in better performance than that by using DJ's thresholds. |
| Keywords: denoise, wavelet, speech signal |
