This technique is compared with conventional denoising methods such as those based on Discrete Wavelet Packet Transform (DWPT) using spectral entropy and spectral subtraction. This comparison is based on signal to noise ratio, SNR and listening tests. In experimental part, the speech signals are corrupted with several types of noises such as White and car ones with different values of SNR. The performance of the bionic wavelet transform has been shown by the obtained results. ER -
