On the Noise Estimation in Wideband Speech by LPC Prediction Error and Spectral Ratio

Abstract

For wideband speech signal, if traditional noise cancelation algorithms are adjusted, it can be operated wrong way since unvoiced speech is similar as white Gaussian noise and high frequency on voiced speech that is over than MVF is also similar as noise in the presence of noise circumstance. So when speech signal is damaged by these reasons, it cannot be… (More)
