Abstract
In this paper, a new and quick method is introduced for speech enhancement. The base or basic of this method is due to filtering the singular value which is obtained from SVD. The efficiency of the proposed methods is its strong capability and the speed of in reduction the noise effect and also does not have the typical “musical tone”, which is usually present in other noise reduction methods. The signals to be experimented are combined with an additive white Gaussian noise for a variety of Signal to Noise Ratio (SNR). These methods will be evaluated in SNR optimization and mean opinion score, which led to remarkable results.
