Original codebase on ESPNet
- 2024.03: I ported the Urhythmic method to this repo. All credits go to the original author. Please check
egs/arctic/vc_urhythmic. - 2023.10: We released a recipe for running AAS-VC on Hi-Fi-CAPTAIN! Please refer to
egs/hificaptain_jp/vc2for details. - 2023.09: We released a recipe for non-autoregressive seq2seq VC! Please refer to
egs/arctic/vc2for details. - 2023.09: We released a recipe for foreign accent conversion (FAC)! Please refer to
egs/l2-arcticfor details.
Sequence-to-sequence (seq2seq) modeling is especially attractive to voice conversion (VC) owing to their ability to convert prosody. In particular, this repository aim to reproduce the results of the following papers/models.
Automatic alignment search (AAS) based non-autoregressive seq2seq VC (paper)
A non-autoregressive seq2seq VC method that can be directly trained on a parallel dataset without any pre-trained models.
Ground-Truth-Free Foreign Accent Conversion (FAC) (paper)
We compared three methods for ground-truth-free FAC. All methods utilize seq2seq modeling and non-parallel frame-based VC models. We provide pre-trained vocoder and non-parallel frame-based VC models.
Voice Transformer Network (VTN) (paper)
This is the first paper that applies the Transformer model to VC. In addition to the model architecture itself, the true novelty of this paper is actually a pre-training technique based on text-to-speech (TTS). This repository provides recipes for (1) TTS pre-training and (2) fine-tuning on a VC dataset. That is to say, TTS is also available in this repository.
Originally I open-sourced the code on ESPNet, but as it grows bigger and bigger, it becomes harder to conduct scientific research on ESPNet. Therefore, this repository aims to isolate the seq2seq VC part from ESPNet to become an independently-maintained toolkit (hopefully).
git clone https://github.com/unilight/seq2seq-vc.git
cd seq2seq-vc/tools
make
Same as many speech processing based repositories (ESPNet, ParallelWaveGAN, etc.), we formulate our recipes in kaldi-style. They can be found in the egs folder. Please check the detailed usage in each recipe.
The experiments in the AAS-VC paper are conducted using the CMU ARCTIC dataset. Please refer to the readme file in egs/arctic/vc2.
The CMU ARCTIC and L2-ARCTIC datasets are used. Please refer to the readme file in egs/l2-arctic.
- The TTS pre-training is conducted on LJSpeech. Please refer to the readme file in
egs/ljspeech/tts1. - Afterwards, the VC fine-tuning is conducted on CMU ARCTIC. Please refer to the readme file in
egs/arctic/vc1.
