Abstract
Reverberation is acoustical distortion which degrades the fidelity and intelligibility of speech signal in a speech recognition system. This paper presents a speech enhancement algorithm using an one-microphone for automatic speech recognition system. The proposed algorithm is based on a simple spectral subtraction. To further improve system performance, we employ a method of Voice Activity Detection (VAD) using spectral entropy.
