Abstract
Adaptive speech recognition is improved by extracting an estimate of the background noise during unknown speech input, and using the noise estimate to modify the noiseless prestored reference speech signals for comparison with the input. Averaged values of autocorrelation coefficient and Toeplitz matrix elements representative of noise frames and prestored reference frames are used to calculate the LPC predictor signals.
