Title: Auditory model for parametrization of speech
Author: H. Hermansky, N. Morgan, and P. Kohn
Group: Patents
Date: September 12, 1995
PDF: [Not available online]
Overview:
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.
