High Rate Vector Quantization in Warped Linear Predictive Coding
Anamika Pathak and M. Tiwari
In this paper the analysis of warped linear predictive coding WLPC using high rate vector quantization with mis-matched distortion measures have been presented. The distortion occurred due to vector quantization is simple quadratically weighted error. Log spectral distortion measures have been computed using sensitivity matrices.It is found that high rate vector quantization is well suited for WLPC techniques in speech compression for human auditory system.
