Adaptive β-order Generalized Spectral Subtraction for Speech Enhancement
スポンサーリンク
概要
- 論文の詳細を見る
While spectral subtraction has widely been used for speech enhancement, the spectral order set in spectral subtraction is generally fixed to some constants, resulting in the performance limitation to a certain degree. In this paper, we first investigate the effect of the spectral order β on the performance of the generalized spectral subtraction that was derived previously [7]. We then propose an adaptive β-order generalized spectral subtraction in which the spectral order is adaptively updated according to the signal-to-noise ratio (SNR) in each critical band frame by frame. Experimental results in various noise conditions are finally presented to illustrate the effectiveness and superiority of the proposed method with regard to the traditional spectral subtraction methods.
