Abstract
In almost all the acoustic environments, noise is always considered as a ubiquitous one. The quality of the signal gets degraded and also contaminated because of the infection, which was caused by various sources when one speaks through the microphone. Here there is a possibility, where there may be a harm caused when human to machine communication happens. The digital filtering problem is considered in this paper, which is the estimation of the clean speech from Noise detection as well as Noise reduction. The estimation is done through linear filtering of noise in the speech signal. In this paper, the author has reviewed different and various speech signal processing techniques, where the noise gets affected and also how the noise gets removed.
