Claim 10:
11. A computer program product for customizing a recurrent neural network transducer (RNN-T), the computer program product comprising one or more computer readable storage media, and program in: collectively stored on the one or more computer readable storage media; the program instructions executable by a computer, to cause the computer to:
synthesize first domain audio data from first domain text data from a first domain;
feed the synthesized first domain audio data into a trained encoder of the recurrent neural network transducer (RN) having an initial condition, and updating the encoder by inputting both the synthesized first domain audio data and the first domain text data;
synthesize second domain audio data from second domain text data from a second domain;
feed the synthesized second domain audio data into the updated encoder of the recurrent neural network transducer (RNN-T), and updating a corresponding predictor by inputting both the synthesized second domain audio data and the second domain text data;
encode a sequence of labels from the first and second domain text data into a text embedding a using the predictor, and combine outputs of the encoder and the predictor with the synthesized first and second domain audio data using a joiner, and
reset the updated encoder to a pre-customized state by restoring weights on the updated encoder to the initial condition including a state trained on the first domain.
