Abstract

Automatic speech recognition is much more difficult in real world. Speech recognition according to SIR (Signal to Interface Ratio) is difficult in situations in which noise of surrounding environment and multi-speaker exists. Therefore, study on main speaker’s voice extractions a very important field in speech signal processing in binaural sound. In this paper, we used directional filter and harmonic filter among other existing methods to extract the main speaker’s information in binaural sound. The main speaker’s voice was extracted using directional filter, and other remaining speaker’s information was removed using harmonic filter through main speaker’s pitch detection. As a result, voice of the main speaker was enhanced.
