Abstract(in English) | In the mobile communication, the speech encoding performance in the environment for instance, with the background noise in the car etc.is paid to attention. In this paper the speech is encoded by the vector quantization by the use of the neural network. First of all, this method reduces the noise by the spectral subtraction method. At this time, ″musical noise″is generated and suppressed by using the identity mapping ability of the neural network and the expressed sound source. It was confirmed that the noise was suppressed to the speech of SNR 0dB by a preliminary listening experiment. |
