Indrayani P. Suryawanshi, Chandraprabha A. Manjare · 2016
A Speech enhancement which is the growth of communication system enhancement means improvement in value of quality of something. This paper explains harmonic noise model (HNM) and MMSE algorithm based speech improvement. There are many types of advantages like provides high quality speech synthesis, speech coding for flexible and effective decomposition of speech. So we use this method for speech enhancement in our project. The analysis results show that the planned methodology exhibits higher noise suppression ability over typical approaches while not obvious degradation of speech quality. The main scope of this method is to remove noise that is introduced by typical strategies suppression in low signal-to-noise environments to get effective suppression.
