(Prototype) RNN Transducer Loss
The RNN transducer loss is used in training RNN transducer models, which is a popular architecture for speech recognition tasks. The prototype loss in torchaudio currently supports autograd, torchscript, float16 and float32, and can also be run on both CPU and CUDA. For more details, please refer to the documentation.
