| 摘 要： | 针对目前在噪音环境下语音识别系统性能较差的问题，利用小波神经网络融合了小波变换良好的时频局域化性质和RBF神经网络具有最佳分类能力和辨识能力等特性。构建了一个用小波基替代RBF网络中激活函数的小波-RBF神经网络结构，并采用全监督训练算法，实现了基于小波-RBF网络的抗噪语音识别系统。实验结果表明该系统比RBF网络具有更好的识别效果，尤其在噪声环境下，具有更强的鲁棒性。

| Abstract: | To solve the problem that recognition rates of speech recognition systems decrease in the noisy environment presently, uses character possessing wavelet neural network which integrates the good time-field local property of wavelet transform,uses character possessing RBF neural network,which have best classification ability and recognize ability etc.This paper constructes a wavelet -RBF neural network structure using Morlet mother -wavelet as wavelet basis stead of activate function in the RBF network,adopts... |
