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。
It reduces the "music noise" using the human auditory characteristics, and enhances the hearing quality using the speech spectrum distribution characteristics in the time-frequency dimension.
