2015
2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Preserved Fulltext
Performance was evaluated in the framework of hybrid neural network -hidden Markov model (NN-HMM) system on TIMIT phoneme sequence recognition task. ...
The best accuracy was obtained by high-level combination of two dimensional cochleogram-spectrogram features using CNN, achieved up to 8.2% relative phoneme error rate (PER) reduction from CNN single features ...
Then, we construct hybrid DNN-HMM and CNN-HMM systems for phoneme sequence recognition task. Here the HMM tied triphone states are used as the neural network target class. ...
