+</div> -->
+
+ZeroSwot is a state-of-the-art zero-shot end-to-end Speech Translation system.
+
+<div align=center><img src="resources/intro.png" height="65%" width="65%"/></div>
+
+The model is created by adapting a wav2vec2.0-based encoder to the embedding space of NLLB, using a novel subword compression module and Optimal Transport, while only utilizing ASR data. It thus enables **Zero-shot E2E Speech Translation to all the 200 languages supported by NLLB**.
+
+For more details please refer to our [paper](https://arxiv.org/abs/2402.10422) and the [original repo](https://github.com/mt-upc/ZeroSwot) build on fairseq.
+
+## Architecture
+
+The compression module is a light-weight transformer that takes as input the hidden state of wav2vec2.0 and the corresponding CTC predictions, and compresses them to subword-like embeddings similar to those expected from NLLB and aligns them using Optimal Transport. For inference we simply pass the output of the speech encoder to NLLB encoder.

+
+## Version
+
+This version of ZeroSwot is trained with ASR data from CommonVoice, and adapted [wav2vec2.0-large](https://huggingface.co/facebook/wav2vec2-large-960h-lv60-self) to the [nllb-200-distilled-600M](https://huggingface.co/facebook/nllb-200-distilled-600M) model.
+
+We have more versions available:

+## Usage
+
+The model is tested with python 3.9.16 and Transformer v4.41.2. Install also torchaudio and sentencepiece for processing.
+
+```bash
+pip install transformers torchaudio sentencepiece
+```
+
+
+```python
+from transformers import Wav2Vec2Processor, NllbTokenizer, AutoModel, AutoModelForSeq2SeqLM
+import torchaudio
+
+def load_and_resample_audio(audio_path, target_sr=16000):
+    audio, orig_freq = torchaudio.load(audio_path)
+    if orig_freq != target_sr:
+        audio = torchaudio.functional.resample(audio, orig_freq=orig_freq, new_freq=target_sr)
+    audio = audio.squeeze(0).numpy()
+    return audio
+
+# Load processors and tokenizers
+processor = Wav2Vec2Processor.from_pretrained("facebook/wav2vec2-large-960h-lv60-self")
+tokenizer = NllbTokenizer.from_pretrained("facebook/nllb-200-distilled-600M")
+
+# Load ZeroSwot Encoder
+commit_hash = "eafabee295ea1c8b45483d1fd26bd747d9a7d937"
+zeroswot_encoder = AutoModel.from_pretrained(
+    "johntsi/ZeroSwot-Medium_asr-cv_en-to-200", trust_remote_code=True, revision=commit_hash,
+)
+zeroswot_encoder.eval()
+zeroswot_encoder.to("cuda")
+
+# Load NLLB Model
+nllb_model = AutoModelForSeq2SeqLM.from_pretrained("facebook/nllb-200-distilled-600M")
+nllb_model.eval()
+nllb_model.to("cuda")
+
+# Load audio file
+audio = load_and_resample_audio(path_to_audio_file) # you can use "resources/sample.wav" for testing
+input_values = processor(audio, sampling_rate=16000, return_tensors="pt").to("cuda")
+
+# translation to German
+compressed_embeds, attention_mask = zeroswot_encoder(**input_values)
+predicted_ids = nllb_model.generate(
+    inputs_embeds=compressed_embeds,
+    attention_mask=attention_mask,
+    forced_bos_token_id=tokenizer.lang_code_to_id["deu_Latn"],
+    num_beams=5,
