Vocoder with HiFIGAN Unit trained on LibriTTS
This repository provides all the necessary tools for using a scalable HiFiGAN Unit vocoder trained with LibriTTS.
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 for more information.
To generate the discrete self-supervised representations, we employ a K-means clustering model trained using facebook/wav2vec2-large-960h-lv60-self 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.
Using the Vocoder
import torch
from speechbrain.inference.vocoders import UnitHIFIGAN
hifi_gan_unit = UnitHIFIGAN.from_hparams(source="speechbrain/hifigan-wav2vec-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.
