# Vocoder with HiFIGAN Unit trained on LibriTTS

This repository provides all the necessary tools for using a [scalable HiFiGAN Unit](https://arxiv.org/abs/2406.10735) vocoder trained with [LibriTTS](https://www.openslr.org/141/). 

The pre-trained model take as input discrete self-supervised representations and produces a waveform as output. This is suitable for a wide range of generative tasks such as speech enhancement, separation, text-to-speech, voice cloning, etc. Please read [DASB - Discrete Audio and Speech Benchmark](https://arxiv.org/abs/2406.14294) for more information.  
To generate the discrete self-supervised representations, we employ a K-means clustering model trained using `facebook/hubert-large-ll60k` hidden layers, with k=1000.

## Install SpeechBrain

First of all, please install tranformers and SpeechBrain with the following command:

```
pip install speechbrain transformers
```

Please notice that we encourage you to read our tutorials and learn more about
[SpeechBrain](https://speechbrain.github.io).


### Using the Vocoder

```python
import torch
from speechbrain.inference.vocoders import UnitHIFIGAN

hifi_gan_unit = UnitHIFIGAN.from_hparams(source="speechbrain/hifigan-hubert-l1-3-7-12-18-23-k1000-LibriTTS", savedir="pretrained_models/vocoder")
codes = torch.randint(0, 99, (100, 1))
waveform = hifi_gan_unit.decode_unit(codes)

```


### Inference on GPU
To perform inference on the GPU, add  `run_opts={"device":"cuda"}`  when calling the `from_hparams` method.


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