# K-means (Quantization)
This folder contains  pre-trained  K-means  models for the LibriSpeech Dataset.
The model serves to quantize self-supervised representations into discrete representation. Thus representations can be used as a discrete audio input for various tasks including classification, ASR and speech gneration.
It supports  kmeans models using the features from  HuBERT, WAVLM or Wav2Vec.

### Training
The model was trained with SpeechBrain.
To train it from scratch follow these steps:
1. Clone SpeechBrain:
```bash
git clone --branch unstable-v0.6 https://github.com/speechbrain/speechbrain/
```
2. Install it:
```bash
cd speechbrain
pip install -r requirements.txt
pip install -e .
```

3. Run Training:
```bash
cd recipes/LibriSpeech/quantization/
pip install -r rextra-requirements.txt
python train.py hparams/train_with_[ssl_model].yaml --data_folder=your_data_folder
```

You can find our training results (models, logs, etc) [here](https://huggingface.co/speechbrain/SSL_Quantization).

### Limitations
The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
