  # Wav2Vec2 base model trained of 3K hours of Vietnamese speech
  The base model is pre-trained on 16kHz sampled speech audio from Vietnamese speech corpus containing 3K hours of spontaneous, reading, and broadcasting speech. When using the model make sure that your speech input is also sampled at 16Khz. Note that this model should be fine-tuned on a downstream task, like Vietnamese Automatic Speech Recognition. 
  
  **Note**: This model does not have a tokenizer as it was pretrained on audio alone. In order to use this model speech recognition, a tokenizer should be created and the model should be fine-tuned on labeled text data. Check out [this blog](https://huggingface.co/blog/fine-tune-wav2vec2-english) for more in-detail explanation of how to fine-tune the model.

  # Usage
  See [this notebook](https://colab.research.google.com/drive/1FjTsqbYKphl9kL-eILgUc-bl4zVThL8F?usp=sharing) for more information on how to fine-tune the English pre-trained model.
  
  ```python
  import torch
  from transformers import Wav2Vec2Model
  
  model = Wav2Vec2Model.from_pretrained("dragonSwing/viwav2vec2-base-3k")
  
  # Sanity check
  inputs = torch.rand([1, 16000])
  outputs = model(inputs)
  ```
