Abstract :
Based upon the theoretical development of a recent paper on scalar parameter quantization of speech reflection coefficients, an experimental comparison study of two quantization methods was undertaken. Quantitative results and subjective evaluation by an experienced listener indicated that as much as 8-10 bits/frame could be eliminated for the same degree of distortion by using the minimum deviation method which embeds parameter probability density information into the quantization process.
