AUDITORY MODEL FOR PARAMETRIZATION OF SPEECH

摘要

USW 0111 PUS AUDITORY MODEL FOR PARAMETRIZATION OF SPEECH A method and system are provided for alleviating the harmful effects of convolutional distortions of speech, such as the effect of a telecommunication channel, on the performance of an automatic speech recognizer (ASR). The technique is based on the filtering of time trajectories of an auditory-like spectrum derived from the Perceptual Linear Predictive (PLP) method of speech parameter estimation.
