%0 Journal Article %T Application of Wavelet LPC Excitation Model for Speech Compression %A Armein Z. R. Langi %J ITB Journal of Engineering Science %D 2008 %I Institut Teknologi Bandung %X This paper presents an application of linear predictive coding (LPC) excitation wavelet models for low bit- rate, high-quality speech compression.The compression scheme exploits the model properties, especially magnitude dependent sensitivity, scale dependent sensitivity, and limited frame length. We use the wavelet model in an open-loop dither based codebook scheme. With this approach, the compression yields a signal-to-noise ratio of at least 11 dB at rates of 5 kbit/s. %K speech processing %K speech compression %K LPC %K LPC excitation %K wavelets %K modelling %U http://journal.itb.ac.id/download.php?file=B08064.pdf&id=328&up=9
