— Surrounding noise and interference will effects the quality of speech during communication. To remove this effect and to improve the quality of speech signal, speech enhancement is one of the most used branches of signal processing. For reduction of noise in speech signals, spectral subtraction can be used and it also requires Voice Activity Detection (VAD) to detect the speech components for a given particular instinct of time. This paper deals with real-time implementation of Spectral Subtraction using Weighted OverLap Add (WOLA) filter bank to suppress noise. From the results, it can be analyzed that the noise is efficiently suppressed using spectral subtraction method and Power spectral density (PSD) of noise suppressed signal obtained from MATLAB and Digital Signal Processor (DSP) kit are studied and compared. |
