%0 Journal Article %T Switched Scalar Quantization with Adaptation Performed on both the Power and the Distribution of Speech Signal %A G. M. Petkovi£¿ %A Z. H. Peri£¿ %A L. V. Stoimenov %J Telfor Journal %D 2011 %I Telecommunications Society, Academic Mind %X This paper analyzes the models for switching scalar quantization of a source with the Laplacian and Gaussian distribution. We have analyzed the results of real telephone speech and proposed a model of switching scalar quantization, which, in addition to adaptation on the power of speech, includes the adaptation on the distribution of signals (Gaussian and Laplacian ), which resulted in a better quality of voice signal pronounced with Signal-to-Quantization-Noise Ratio. %K Quantization algorithms %K speech signal processing %K switched scalar quantization %U http://journal.telfor.rs/Published/Vol3No2/Vol3No2_A5.pdf
