I tried lstm/res-lstm/gan-res-lstm, use the same configurations, all experiments got performance degrading. I don't know what's wrong. The back-end asr system is tdnn+lstm. front-end is feature mapping from aishell_train_clean+rvb to aishell_train_clean . Do you have any suggestions or insights ? thank you very much !
