asr

Automatic Speech Recognition (ASR)

Usage

For ASR track, we provide two baseline systems includes single-speaker and multi-speaker ASR. For single-speaker, please run all steps in ./run_local_conformer_near_alimeeting.sh, while ./run_local_multispeaker_conformer_alimenting.sh is used for the multi-speaker ASR.

The main stage:

1. We use the implementation of Conformer ASR model in the ESPnet2. Please install the latest ESPnet toolkit and copy our all files to the espnet/egs2/AliMeeting/asr.
2. Both data preparation, language model training, and ASR model training are included in asr_local.sh.
3. First, please run ./run_local_conformer_near_alimeeting.sh to train the single-speaker ASR model. Then, run run_local_multispeaker_conformer_alimeeting.sh to train the multi-speaker ASR model. Please note that you don’t need to repeat the data preparation procedure in the multi-speaker ASR training, since all the preparation will be done in the first training.
