Before revision:  Our experiments on  AISHELL-1 using WeNet, not only give a promising character error rate (CER) on a unified streaming and non-streaming two pass (U2) E2E model but also show reasonable RTF and latency, both of these aspects are favored for production adoption. The toolkit is publicly available at URL\\%DIF > relative character error rate (CER) reduction in non-streaming ASR compared to a standard non-streaming transformer.
After revision:  Our experiments on AISHELL-1 dataset using WeNet show that, our model achieves 5.03\\%DIF > relative character error rate (CER) reduction in non-streaming ASR compared to a standard non-streaming transformer.
