Abstract
A computer-implemented method is provided for training a Recurrent Neural Network Transducer (RNN-T). The method includes training, by inputting a set of audio data, a first RNN-T which includes a common encoder, a forward prediction network, and a first joint network combining outputs of both the common encoder and the forward prediction network. The forward prediction network predicts label sequences forward. The method further includes training, by inputting the set of audio data, a second RNN-T which includes the common encoder, a backward prediction network, and a second joint network combining outputs of both the common encoder and the backward prediction network. The backward prediction network predicts label sequences backward. The trained first RNN-T is used for inference.
