In this study, we apply BNF for Vietnamese speech recognition with five layers MLP network of different sizes for the first hidden layer. Input features to extract BNF feature are Perceptual Linear Prediction(PLP) and Mel Frequency Cepstral Coeffcient(MFCC). The experiments are carried out on a data set of VOV(Voice of Vietnam).The results show that using BNF for Vietnamese speech recognition, a… Show more
