Abstract :
We apply the relative entropy functional to sets of line-spectrum pairs (LSPs) and transform-based generalized spectral pmfs of Gibson et al. (1993) and present experimental results for sequence segmentation and vector quantization which show that the relative entropy of these quantities is a useful indicator for variable-rate speech coding
