Add modified transducer loss for AIShell dataset (#219) 
* Add modified transducer for aishell.

* Minor fixes.

* Add extra data in transducer training.

The extra data is from http://www.openslr.org/62/

* Update export.py and pretrained.py

* Update CI to install pretrained models with aishell.

* Update results.

* Update results.

* Update README.

* Use symlinks to avoid copies.

Introduction

The decoder, i.e., the prediction network, is from https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=9054419 (Rnn-Transducer with Stateless Prediction Network)

You can use the following command to start the training:

cd egs/aishell/ASR

export CUDA_VISIBLE_DEVICES="0,1,2,3,4,5,6,7"

./transducer_stateless/train.py \
  --world-size 8 \
  --num-epochs 30 \
  --start-epoch 0 \
  --exp-dir transducer_stateless/exp \
  --max-duration 250 \
  --lr-factor 2.5
