Approaches to high quality speech coding using gain-adaptive vector quantization
Albert P. Berg, W.B. Mikheal · 2003
Preliminary results of ongoing research to utilize vector quantization to achieve practical high quality speech coding at 8 kb/s are reported. The basic concepts of speech coding and vector quantization are discussed, followed by a description of the gain adaptive time domain vector quantizer and the gain adaptive transform domain vector quantizer. The quantitative and qualitative performance of the proposed coding systems is presented.>
