This model is a reworked CTC attention model trained with the code from github.com/k2-fsa/icefall/tree/master/egs/librispeech/ASR/conformer_ctc2. The model has 12 layers of reworked Conformer encoder layers and 6 reworked Transformer decoder layers. Number of model parameters is 103,071,035. With full Librispeech data set, it was trained for only 30 epochs because the reworked model would converge much faster.
