* disable speed perturbation by default

* minor fixes

* minor updates

* updated bash scripts to incorporate with the `speed-perturb` arg

* minor fixes

1. changed the naming scheme from `speed-perturb` to `perturb-speed` to align with the librispeech recipe

Introduction

This recipe includes some different ASR models trained with Aishell2.

./RESULTS.md contains the latest results.

Transducers

There are various folders containing the name transducer in this folder. The following table lists the differences among them.

Encoder Decoder Comment
pruned_transducer_stateless5 Conformer(modified) Embedding + Conv1d same as pruned_transducer_stateless5 in librispeech recipe

The decoder in transducer_stateless is modified from the paper Rnn-Transducer with Stateless Prediction Network. We place an additional Conv1d layer right after the input embedding layer.
