Abstract
A speech recognition method that combines HMMs and vector quantization to model the speech signal and adds spectral derivative information in the speech parameters. Each state of a HMM is modeled by two different VQ-codebooks. One is trained by using the spectral parameters and the second is trained by using the spectral derivative parameters.
