Abstract

To solve the problem that recognition rates of speech recognition systems decrease in the noisy environment presently, a novel wavelet-RBF network model is presented in this paper. The model combines the time-frequency localization characteristic of wavelet and RBF neural network with the best classification capacity and ability of identification. A speech recognition system is mapped through wavelet-RBF network, which helps to overcome the defects of ANN such as the difficulty of rationally determining the network structure and the existence of partial optimal points. The experimental results show that the wavelet-RBF network is better than RBF network in SNRs and recognition rates.
