This paper studies the speech enhancement technology, and proposes an improved spectral subtraction method based on the auditory characteristics and the speech spectrum characteristics.

主要以谱减法为基础，结合人耳的听觉特性从而减少残留“音乐噪声”的影响；结合语音的语谱在时-频域分布特性从而提高增强后语音的听觉质量。

An array crosstalk resistant adaptive noise cancellation method is therefore presented. And then an improved spectral subtraction algorithm is further cascaded to obtain better enhancement results.

为此给出一种阵列抗串扰自适应噪声抵消方法，并将其与改进的谱相减技术相结合。
