摘要
讨论了在强噪声环境下将自适应滤波算法与非线性谱相减算法相结合的语音增强方法。仿真结果表明,在大大消除背景噪声的同时,该方法还有效地抑制了“音乐噪声”,运算量小,适用于强噪声环下的有声/无声检测。
this paper presents a new algorithm which can be used to extract weak speech signal from strong noise environment.It is a combination algorithm of LMS algorithm with a nonlinear spectral subtraction algo-rithm.The simulation result shows its excellent performance in background noise and“music noise”cancellation.[
