Abstract

This paper presents a review of LPC methodsfor enhancement of speech signals.The purposeof all method of speech enhancement is to improve quality of speech signal by minimizing the background noise. This paper especiallycomments on Power Spectral Subtraction, Multiband Spectral Subtraction, Non-Linear Spectral Subtraction Method, MMSE Spectral Subtraction Method and Spectral Subtraction based on perceptual properties.As the spectral subtraction produces the Residual noise, Musical noise, Linear Predictive Analysis method is used to enhance the Speech.
