Prefix tree based n-best list re-scoring for recurrent neural network language model used in speech recognition system

Recurrent Neural Network Language Model (RNNLM) has recently been shown to outperform N-gram Language Models (LM) as well as many other competing advanced LM techniques. However, the training and testing of RNNLM are very time-consuming, so in real-time recognition systems, RNNLM is usually used for re-scoring a limited size of n-best list. In this paper… CONTINUE READING
