摘要
基本谱减法在在低信噪比下滤波性能不佳,会有大量的噪声残留,本文提出一种基于能量阈值的自适应谱减滤波算法,并进一步引入基于Teager能量算子的语音端点检测,实现低信噪比下的语音降噪。
The basic spectral subtraction method has poor filtering performance at low SNR,resulting in a large amount of residual noise.This paper proposes an adaptive spectral subtraction filtering algorithm based on energy threshold.the speech endpoint detection based on Teager energy operator is further introduced to realize speech noise reduction under low SNR.
