Title
ROBUST SPECTRUM QUANTIZATION FOR LP PARAMETER ENHANCEMENT
Abstract
In this paper, we investigate the denoising properties of ro- bust vector quantization of the speech spectrum parameters in combination with a Kalman lter . The underlying assump- tion is that the high-energy speech regions can be used to re- construct the low-energy regions destroyed by noise. This can be achieved through vector quantization with a properly weighted distortion measure. The performance of the pro- posed system, Kalman ltering with prior vector quantiza- tion, is compared with existing schemes for parameter esti- mation used in Kalman ltering. The results indicate signif- icant improvement over the reference systems in both objec- tive and subjective tests.
