摘要
Abstract
A new kind of noise-robust speech features is proposed in this paper. The power spectrum of the speech signal is filtered by a bank of band-pass filter and the differences of the filters＇ outputs can be the feature vector.Theoretical analysis and experimental results show that the recognizer using the proposed feature can improve its performance greatly in noisy environments.关键词
