https://huggingface.co/facebook/hubert-base-ls960 with ONNX weights to be compatible with Transformers.js.

## Usage (Transformers.js)

If you haven't already, you can install the [Transformers.js](https://huggingface.co/docs/transformers.js) JavaScript library from [NPM](https://www.npmjs.com/package/@xenova/transformers) using:
```bash
npm i @xenova/transformers
```

**Example:** Load and run a `HubertModel` for feature extraction.
```javascript
import { AutoProcessor, AutoModel, read_audio } from '@xenova/transformers';

// Read and preprocess audio
const processor = await AutoProcessor.from_pretrained('Xenova/hubert-base-ls960');
const audio = await read_audio('https://huggingface.co/datasets/Xenova/transformers.js-docs/resolve/main/jfk.wav', 16000);
const inputs = await processor(audio);

// Load and run model with inputs
const model = await AutoModel.from_pretrained('Xenova/hubert-base-ls960');
const output = await model(inputs);
// {
//   last_hidden_state: Tensor {
//     dims: [ 1, 549, 768 ],
//     type: 'float32',
//     data: Float32Array(421632) [0.0682469978928566, 0.08104046434164047, -0.4975186586380005, ...],
//     size: 421632
//   }
// }
```

Note: Having a separate repo for ONNX weights is intended to be a temporary solution until WebML gains more traction. If you would like to make your models web-ready, we recommend converting to ONNX using [🤗 Optimum](https://huggingface.co/docs/optimum/index) and structuring your repo like this one (with ONNX weights located in a subfolder named `onnx`).
