A Speech Recognition Method of Isolated Words Based on Modified LPC Cepstrum

Abstract

The measurement of Mel spectrum distortion is a kind of warped frequency spectrum distortion measure. Using Mel frequency scale can reflect sufficiently the nonlinear perceptive characteristic of human hearings to frequency and amplitude. It can also reflect the frequency analysis and spectrum synthesis characteristics when human hear complex sounds. Aiming… (More)
