Traditional speech recognition model based on deep neural network (DNN) and hidden Markov model (HMM) is a complex and multi-module system.In other words,optimization goals may differ between modules in traditional model.Besides,additional language resources are required,such as pronunciation dictionary and language model.To eliminate the drawbacks of traditional model,we hereby propose an end-to-end speech recognition method,where connectionist temporal classification (CTC) and attention are integrated for decoding.In our model,the complex modules are replaced by a single deep network.Our model mainly consists of encoder and decoder.The encoder is constructed by bidirectional long short-term memory (BLSTM) with a triangular structure for feature extraction.The decoder based on CTC-attention decoding utilizes advanced features extracted by shared encoder for training and decoding.The experimental results on the VoxForge dataset indicate that end-to-end method is superior to basic CTC and attention-based encoder-decoder decoding,and the character error rate (CER) is reduced to 12.9％ without using any language model.
