Abstract

In Speech communication, Degradation of speech due to background noise is very big problem. This paper presents two
noise reduction techniques like Spectral Subtraction and Wiener Filter and presents our simulation results of these noise reduction
techniques. It is shown that system is removed the background noise almost completely from noisy speech and gives the best SNR
values.
