摘要
介绍了一种根据传统的谱减改进后的增强算法:根据每帧的功率谱来动态调整谱减系数,然后采用多种方法抑制音乐噪声。使谱减效果既保持了较高的信噪比,又使音乐噪声得到了抑制。算法在VC6.0下编程实现,实验证明语音增强效果明显。
A new improved spectral subtraction algorithm is presented. This method gives different estimate values based on the signal power to improve the spectral subtraction. The experiment by means of the C language shows that this method improves the speech-sound quality effectively and reduces the musical noise.
