+# Wav2Vec2-Large
+
+[Paper](https://arxiv.org/abs/2006.11477)
+
+Authors: Alexei Baevski, Henry Zhou, Abdelrahman Mohamed, Michael Auli
+
+**Abstract**
+We show for the first time that learning powerful representations from speech audio alone followed by fine-tuning on transcribed speech can outperform the best semi-supervised methods while being conceptually simpler. wav2vec 2.0 masks the speech input in the latent space and solves a contrastive task defined over a quantization of the latent representations which are jointly learned. Experiments using all labeled data of Librispeech achieve 1.8/3.3 WER on the clean/other test sets. When lowering the amount of labeled data to one hour, wav2vec 2.0 outperforms the previous state of the art on the 100 hour subset while using 100 times less labeled data. Using just ten minutes of labeled data and pre-training on 53k hours of unlabeled data still achieves 4.8/8.2 WER. This demonstrates the feasibility of speech recognition with limited amounts of labeled data.
+The original model can be found under https://github.com/pytorch/fairseq/tree/master/examples/wav2vec#wav2vec-20.

+# Convert from FAIRSEQ to HF
+
+1. Create a config
+
+```python
+from transformers import Wav2Vec2Config
+config = Wav2Vec2Config.from_pretrained('facebook/wav2vec2-large')
+config.conv_bias = True
+config.feat_extract_norm = "layer"
+config.save_pretrained('./')
+```
+
+2. Convert using [the script](https://github.com/huggingface/transformers/blob/main/src/transformers/models/wav2vec2/convert_wav2vec2_original_pytorch_checkpoint_to_pytorch.py) written by HF team
+
+```bash
+wget convert_wav2vec2_original_pytorch_checkpoint_to_pytorch.py
+
+hf_name="<my-hf-repo-name>"
+ckpt="<path-to-pth-checkpoint>"
+
+python ./convert_wav2vec2_original_pytorch_checkpoint_to_pytorch.py \
+    --pytorch_dump_folder ${hf_name} \
+    --checkpoint_path ${ckpt} \
+    --config_path ./config.json \
+    --not_finetuned
+```
