Accuracy of streaming rnn transducer

A computer program product for model training, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:

• training a second end-to-end neural speech recognition model that has a bidirectional encoder to output same symbols from an output probability lattice of the second end-to-end neural speech recognition model as from an output probability lattice of a trained first end-to-end neural speech recognition model having a unidirectional encoder;
• and
• building a third end-to-end neural speech recognition model configured to stream output data and comprising a unidirectional encoder by training the third end-to-end speech recognition model as a student using the trained second end-to-end neural speech recognition model as a teacher in a knowledge distillation method, with output data being provided offline.
