| 摘 要： | 依据航空噪声的频谱特性，提出将自适应滤波算法与改进的谱减法相级联的方法来增强语音。在强航空噪声背景下，处理后的语音不仅信噪比得到了很大提高，而且在有效抑制背景噪声和音乐噪声的同时，其清晰度和可懂度也得到了很大的改善。

| Abstract: | Based on analysis of the characteristics of the power spectrum of aviation noise, this paper proposes a method to enhance speech by a cascaded connection of LMS algorithm with improved spectral subtraction algorithm. Experimental results show that the new method can suppress background noise and music noise under strong aviation noise, and both SNR and articulation are improved dramatically. |
