Speech Recognition Research Based On Probabilistic Neural Network of RBF
Automatic speech recognition(ASR) is an important topic to be performed by a computer system. This paper improved the radial basis function(RBF) nerual network,and put forward the radial basis function probabilistic neural network(RBFPNN),which is a combination of RBF and Probabilistic Neural Network (PNN). All of the classifiers use a hybrid Linear Prediction Cepstrum Coefficient(LPCC) and MelFrequency Cepstrum Coefficient(MFCC) as their features for classification. RBFPNN is used for pattern classification and recognition,which improved flexibility and recognition performance. A recognition accurary of 89.7% could be achieved from this experiment. The experiment shows that BRFPNN improves the recognition accurary and speed.
