# Model Name

This is a multilingually fine-tuned version of [NLLB](https://arxiv.org/abs/2207.04672) based on [nllb-200-distilled-1.3B](https://huggingface.co/facebook/nllb-200-distilled-1.3B) using the text data of [MuST-C v1.0](https://aclanthology.org/N19-1202/) (En -> 8).

It is part of the paper [Pushing the Limits of Zero-shot End-to-end Speech Translation](https://arxiv.org/abs/2402.10422). Details for the fine-tuning process are available at Appendix D.

## Usage

```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("johntsi/nllb-200-distilled-1.3B_mustc_en-to-8")
model = AutoModelForSeq2SeqLM.from_pretrained("johntsi/nllb-200-distilled-1.3B_mustc_en-to-8")

model.eval()
model.to("cuda")

text = "Translate this text to German."
inputs = tokenizer(text, return_tensors="pt").to("cuda")
outputs = model.generate(
    **inputs,
    num_beams=5,
    forced_bos_token_id=tokenizer.lang_code_to_id["deu_Latn"]
)
translated_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(translated_text)
```
