* 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
|
|
|
|
Please refer to <https://icefall.readthedocs.io/en/latest/recipes/aishell.html>

|
for how to run models in this recipe.

# Transducers
|
|
|
|
There are various folders containing the name `transducer` in this folder.
|
|
The following table lists the differences among them.
|
|
|
|
| | Encoder | Decoder | Comment |
|
|
|------------------------------------|-----------|--------------------|-----------------------------------------------------------------------------------|
|
|
| `transducer_stateless` | Conformer | Embedding + Conv1d | with `k2.rnnt_loss` |
|
|
| `transducer_stateless_modified` | Conformer | Embedding + Conv1d | with modified transducer from `optimized_transducer` |
|
|
| `transducer_stateless_modified-2` | Conformer | Embedding + Conv1d | with modified transducer from `optimized_transducer` + extra data |
|
|
|
|
The decoder in `transducer_stateless` is modified from the paper
|
|
[Rnn-Transducer with Stateless Prediction Network](https://ieeexplore.ieee.org/document/9054419/).
|
|
We place an additional Conv1d layer right after the input embedding layer.
