| 摘 要： | 人耳对于声音信号的分辨率是非线性的,而仿生小波变换正是由非线性的耳蜗听觉模型发展而来。文章提出一种基于仿生小波变换的语音信号去噪方法,同时针对软硬阈值函数的不足,采用一种修正的硬阈值函数进行处理。仿真结果表明,该方法具有较好的增强效果。 |
| 关 键 词： | 仿生小波变换 语音增强 阈值函数 |

| Abstract: | The frequency resolution of human ear has non-linear characteristics,while BWT(Bionic Wavelet Transform)derives from a nonlinear auditory model of the cochlea.In this paper,a algorithm is proposed for speech de-noising using Bionic Wavelet Transform, some modification is given to hard threshold approach for its drawback.Simulation results indicate that this new method has improved the effect of denoising. |
| Keywords: | bionic wavelet Transform speech enhancement threshold function |
