Vocoder with HiFIGAN Unit trained on LJSpeech

This repository provides all the necessary tools for using a HiFiGAN Unit vocoder trained with LJSpeech.

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==4.28.0

Please notice that we encourage you to read our tutorials and learn more about SpeechBrain.

Transcribing your own audio files

from speechbrain.pretrained import UnitHIFIGAN

hifi_gan_unit = UnitHIFIGAN.from_hparams(source="speechbrain/hifigan-unit-hubert-l6-k100-ljspeech")
codes = torch.randint(0, 99, (100,))
waveform = hifi_gan.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.
