| 摘 要： | 飞机、坦克和船舶等封闭座舱内部产生的强机械噪声严重地影响了语音通信系统,为此,提出了自适应噪声抵消与谱相减结合的单通道语音消噪算法,其基本原理是:先进行基于相关检测的自适应消噪处理,其后采用谱相减算法消除残留噪声。仿真结果表明:该算法对引擎噪声的消噪效果明显,并能有效地保持语音清晰度,可应用于机械噪声很强的语音通信系统。

| Abstract: | The strong mechanical noise produced in the closed cockpit of tanks,planes,and ships has greatly influenced voice communication system. Aiming at the problem,the single-channel speech noise elimination algorithm combining adaptive noise canceling with spectral subtraction is proposed in the paper. The basic principle of the algorithm is making adaptive noise cancelling based on correlation detection at first,and then using spectral subtraction algorithm to eliminate the residual noise. The simulation result... |
