Abstract

In this paper, we proposed a new method for SPEECH ENHANCEMENT. The method is based on wavelet SPECTRAL SUBTRACTION. We use linear predictive coding (LPC) for NOISE estimation and extraction. The proposed method was compared with the wavelet SPECTRAL SUBTRACTION method. The new method increased signal to NOISE ratio of the NOISE contaminated speech signal more than wavelet SPECTRAL SUBTRACTION method. Also, good results have been achieved in auditory test (Mean Opinion Score).
