摘要

在本文中，我们提出了一种频域降噪方法用于语音增强。该方法利用运行谱滤波(RSF)抑制语音信号中的加性噪声。RSF是频域的数字滤波。使用RSF的降噪方法不需要估计噪声谱。我们提出了一种利用RSF来降低语音降噪产生的音乐噪声的方法。实验结果表明，RSF可以有效地降低音乐噪声。

The effect of the musical noise suppression in speech noise reduction using RSF

In this report, we propose a noise reduction method in the frequency domain for speech enhancement. Additive noise in a speech signal is suppressed by this method using running spectrum filtering (RSF). RSF is digital filtering in the frequency domain. The noise reduction method using RSF does not need estimated noise spectra. We propose a method of reducing the musical noise generated by speech noise reduction which uses RSF. Our experimental results show that musical noise is reduced using RSF.
