Simultaneously Trained NN-based Acoustic Model and NN-based Feature Extractor
Original language description
This paper demonstrates how standard feature extraction methods such as PLP can be successfully replaced by a neural network and methods such as mean normalization, variance normalization and delta coefficients can be simultaneously utilized in a neural-network-based acoustic model. Our experiments show that this replacement is significantly beneficial. Moreover, in our experiments, also a neural-networkbased voice activity detector was employed and trained simultaneously with a neural-network-based feature extraction and a neural-networkbased acoustic model. The system performance was evaluated on the British English speech corpus WSJCAM0.
