## ESPnet2 ASR model

### `espnet/shihlun-asr-commonvoice-zh-TW`
This model was trained by Shih-Lun Wu using the commonvoice recipe in [espnet](https://github.com/espnet/espnet/).
### Demo: How to use in ESPnet2
```bash
cd espnet
pip install -e .
cd egs2/commonvoice/asr1
./asr.sh \
  --stage 1 \
  --stop_stage 13 \
  --nj 32 \
  --inference_nj 32 \
  --skip_train true \
  --train_set "train_zh_TW" \
  --valid_set "dev_zh_TW" \
  --test_sets "dev_zh_TW test_zh_TW" \
  --lang "zh_TW" \
  --local_data_opts "--lang zh-TW" \
  --speed_perturb_factors "0.9 1.0 1.1" \
  --lm_train_text "data/train_zh_TW/text" \
  --token_type bpe \
  --nbpe 2542 \
  --bpemode "unigram" \
  --bpe_train_text "data/train_zh_TW/text" \
  --use_lm false \
  --inference_asr_model "valid.acc.best.pth" \
