Non-Intrusive Noise Reduction in GSM Voice Signal Using Non-Parametric Modeling Technique.

Abstract

Noise degrades the quality and intelligibility of speech. It impedes speech clarity, coding, recognition and speaker identification. To mitigate noise effect and improve speech quality, we propose a Non-parametric modeling technique along with a Non-intrusive signal denoising system based on short-time Fourier transforms. This paper aims to establish only the idea behind our proposed algorithm, however, we present an argument to justify that our results will reduce an end-to-end acoustic background noise; improve the quality of speech for both the speaker and the listener, and eventually increase throughput. Ultimately, users’ will be able to call and receive calls in a noisy environment while enjoying clarity of voice.
