| 摘 要： | 提出了一种基于传统谱相减语音增强算法的改进方法,加强了其滤除噪声的功效,提高了强噪声背景下语音信号的信噪比和可懂度。实验表明,该算法能够很好地滤除强噪声,增强语音,甚至对于滤除与语音频段几乎重叠的噪声信号,效果也十分显著。最后与传统减谱法相比较,分析了该算法的优缺点。

| Abstract: | In order to enhance the effect of noise reduction,and to improve the SNR and comprehension of speech, we put forward a speech enhancement method based on the traditional spectrum subtraction method.The results of experiment show that using the method noise can be perfectly wiped off,and the speech is enhanced.Even for the noise whose spectrum is almost the same as that of the speech,it works well.Finally,comparing the method with traditional spectrum subtraction method,its merits and defects are summarized. |
