# Vocoder with HiFIGAN Unit trained on LJSpeech |
|
|
|
This repository provides all the necessary tools for using a [HiFiGAN Unit](https://arxiv.org/abs/2104.00355) vocoder trained with [LJSpeech](https://keithito.com/LJ-Speech-Dataset/). |
|
|
|
The pre-trained model take as input discrete self-supervised representations and produces a waveform as output. Typically, this model is utilized on top of a speech-to-unit translation model that converts an input utterance from a source language into a sequence of discrete speech units in a target language. |
|
To generate the discrete self-supervised representations, we employ a K-means clustering model trained on the 6th layer of HuBERT, with `k=100`. |

## 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 |

|
|
### Using the Vocoder |
|
|
|
```python |
|
import torch |
|
from speechbrain.inference.vocoders import UnitHIFIGAN |
|
|
|
hifi_gan_unit = UnitHIFIGAN.from_hparams(source="speechbrain/tts-hifigan-unit-hubert-l6-k100-ljspeech", savedir="pretrained_models/tts-hifigan-unit-hubert-l6-k100-ljspeech") |
|
codes = torch.randint(0, 99, (100,)) |
|
waveform = hifi_gan_unit.decode_unit(codes) |
|
|
|
``` |
|
|
|
### Using the Vocoder with the S2UT |
|
```python |
|
import torch |
|
import torchaudio |
|
from speechbrain.inference.ST import EncoderDecoderS2UT |
|
from speechbrain.inference.vocoders import UnitHIFIGAN |
|
|
|
# Intialize S2UT (Transformer) and Vocoder (HiFIGAN Unit) |
|
s2ut = EncoderDecoderS2UT.from_hparams(source="speechbrain/s2st-transformer-fr-en-hubert-l6-k100-cvss", savedir="pretrained_models/s2st-transformer-fr-en-hubert-l6-k100-cvss") |
|
hifi_gan_unit = UnitHIFIGAN.from_hparams(source="speechbrain/tts-hifigan-unit-hubert-l6-k100-ljspeech", savedir="pretrained_models/tts-hifigan-unit-hubert-l6-k100-ljspeech") |
|
|
|
# Running the S2UT model |
|
codes = s2ut.translate_file("speechbrain/s2st-transformer-fr-en-hubert-l6-k100-cvss/example-fr.wav") |
|
codes = torch.IntTensor(codes) |
|
|
|
# Running Vocoder (units-to-waveform) |
|
waveforms = hifi_gan_unit.decode_unit(codes) |
|
|
|
# Save the waverform |
|
torchaudio.save('example.wav',waveforms.squeeze(1), 16000) |
|
``` |
|
|
|
### 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. |
