摘要
讨论在强噪声环境下语音增强的新方法,即将主从结构的自适应滤波算法与级联谱相减算法相结合的方法。计算机仿真结果表明,该方法在大大消除背景噪声的同时,消除了“音乐噪声”,同时保持了较好的语音可懂度。
This paper presents a new method which is used to extract speech signal from strong noise environment.This method is a combination of adaptive noise cancellation algorithm with master-slave structure and repetitive spectral subtraction algorithm.The simulation result shows its excellent performance in the elimination of background noise and'music noise'can-cellation.[
