Reproducing stt_en_conformer_ctc_medium_ls training details
Hello,

I'm trying to train conformer_ctc_medium model from scratch. I use the config file from the pretrained model stt_en_conformer_ctc_medium_ls and only change the manifest_filepath and batch_size configuraion (I changed the batch_size to 16 to fit my GPU).

After training 42 epoches, the WER on librispeech validate data (about 15%) is still much higher than the pretrained stt_en_conformer_ctc_medium_ls model. 

May I know the trained epoch of the pretrained model stt_en_conformer_ctc_medium_ls ? Or is there any other configuration or training process I should pay attention to acheive similar results as the pretrained model ?

Thank you very much!
