Emformer is an efficient memory-transformer-based streaming acoustic model that has demonstrated state-of-the-art streaming automatic speech recognition (ASR) performance in low-latency, resource-constrained scenarios, such as on-device applications (citation: https://arxiv.org/abs/2010.10759).
The TorchAudio v0.11 release includes the following beta features:

Implementation of Emformer (docs)
Recurrent neural network transducer (RNN-T) streaming ASR model that uses Emformer for its transcription network (docs)
RNN-T beam search decoder with TorchScript support (docs)
