## ESPnet2 ASR model

This is a simple baseline for the ML-SUPERB 2.0 Challenge. It is a self-supervised [MMS 1B](https://huggingface.co/facebook/mms-1b) model fine-tuned on [142 languages of ML-SUPERB](https://huggingface.co/datasets/ftshijt/mlsuperb_8th) using CTC loss.
The MMS model is frozen and used as a feature extractor for a small Transformer encoder during fine-tuning, which took approximately 1 day on a single GPU. 


The model was trained using the [ML-SUPERB recipe](https://github.com/espnet/espnet/tree/master/egs2/ml_superb/asr1) in ESPnet. Inference can be performed with the following script:

```
from espnet2.bin.asr_inference import Speech2Text

model = Speech2Text.from_pretrained(
  "espnet/mms_1b_mlsuperb"
)

speech, rate = soundfile.read("speech.wav")
text, *_ = model(speech)[0]
```
