Abstract(in English) | Speech recognition systems have come to be used widely. When surrounding noises disturb a speech recognition system, considerable reduction in the recognition rate is inevitable. We have to develop noise reduction methods so that any speech recognition system can be used in realistic environments. We propose a novel method for reducing the noise. The reduction is achieved by applying image processing techniques to the corresponding spectrograms. Experiments were conducted on speech sounds contaminated with noises. The performances were evaluated by the cross correlation measure and compared with other methods. The proposed method was much superior to other methods. |
