In this paper, we present an application of spectral subtraction (SS) algorithm in speech enhancement system to extract the pure speech signal as far as possible. In contrast to the existing research, the proposed algorithm improves the voice quality, which reduces speech distortion, eliminates background noise and improves the speech intelligibility. This paper first introduces the research significance of the speech enhancement, then introduces the relevant theories of speech signal processing, and expounds the basic spectral subtraction speech enhancement, through a lot of simulation experiments verify the effect of spectral subtraction. Based on the voice activation detection algorithm is studied and an improved spectrum subtraction(ISS)algorithm was presented. Our simulation results show that the proposed ISS Algorithm is effective with the lower computational complexity in speech enhancement system.
