反復ウェーブレット雑音除去を用いた音声強調 <Abstract> This paper presents a wavelet denoising. In the proposed method, we use the output signal of wavelet denoising as the input signal again. This process is iterated a few times. From the investigation of segmental SNR and Itakura-Saito distortion measure, we show the speech enhancement using the proposed method reduces both musical noise and speech distortion. |
