摘　　要：在多媒体视频会议系统中,语音处理是关键环节,而解决多路混音后的溢出噪声问题是语音处理的核心。现有的混音算法存在音量突变的问题,通过对其分析,找出了最主要的原因。在此基础上,提出了一种改进的算法——自对齐减谱法,经仿真结果表明:该算法消除噪声效果更明显,可用于多媒体视频会议系统中。Audio processing is very important in the multimedia conference system. How to solve the problem of overflow after audio mixing is the core of audio processing. Now, the existing algorithms have a problem which is volume change. A self-aligning spectral method is proposed in this paper by analyzing the existing problems in the audio mixing algorithms. The experimental results show that this algorithm has more obvious denoising effects, and it can be used in the multimedia conference system.

关 键 词：语音处理 混音算法 溢出 自对齐减谱法
