  • Abstract
    In this paper, we have focused on finding an error resilient method for discontinuity-less transmission of speech signals in the Internet. Our proposed method creates artificial correlation between speech samples that pre-distorts the speech signal. The receiver uses this correlation to reconstruct the lost speech packets. A discrete Fourier transform (DFT)-based speech enhancement technique is designed for the reduction of the processing error in the recovered speech caused by the speech codecs. The SegSNR results show the superiority of our proposed method over a proposed speech enhancement technique.
