Abstract: Aim of speech enhancement is to improve the intelligibility and quality of the speech. By recording the speech signal in the noisy environment, clean speech signals are degraded. Speech enhancement reduces the noise without distorting the original (clean) signal. In this concept, Multi-Band Spectral Subtraction (MBSS) method is used to enhance the noisy speech signal. This approach, takes into account the fact that colored noise affects the speech spectrum differently at various frequencies. Then the properties of this method are derived in terms of input and output SNR.
