Nytro Posted September 22, 2019 Report Posted September 22, 2019 Real-Time Voice Cloning This repository is an implementation of Transfer Learning from Speaker Verification to Multispeaker Text-To-Speech Synthesis (SV2TTS) with a vocoder that works in real-time. Feel free to check my thesis if you're curious or if you're looking for info I haven't documented yet (don't hesitate to make an issue for that too). Mostly I would recommend giving a quick look to the figures beyond the introduction. SV2TTS is a three-stage deep learning framework that allows to create a numerical representation of a voice from a few seconds of audio, and to use it to condition a text-to-speech model trained to generalize to new voices.

You can use your trained encoder models from this repo with it. 06/07/19: Need to run within a docker container on a remote server? See here. 25/06/19: Experimental support for low-memory GPUs (~2gb) added for the synthesizer. Pass --low_mem to demo_cli.py or demo_toolbox.py to enable it. It adds a big overhead, so it's not recommended if you have enough VRAM. Quick start Requirements You will need the following whether you plan to use the toolbox only or to retrain the models. Python 3.7. Python 3.6 might work too, but I wouldn't go lower because I make extensive use of pathlib. Run pip install -r requirements.txt to install the necessary packages. Additionally you will need PyTorch (>=1.0.1). A GPU is mandatory, but you don't necessarily need a high tier GPU if you only want to use the toolbox. Pretrained models Download the latest here. Preliminary Before you download any dataset, you can begin by testing your configuration with: python demo_cli.py If all tests pass, you're good to go. Datasets For playing with the toolbox alone, I only recommend downloading LibriSpeech/train-clean-100. Extract the contents as <datasets_root>/LibriSpeech/train-clean-100 where <datasets_root> is a directory of your choosing. Other datasets are supported in the toolbox, see here. You're free not to download any dataset, but then you will need your own data as audio files or you will have to record it with the toolbox. Toolbox You can then try the toolbox: python demo_toolbox.py -d <datasets_root> orpython demo_toolbox.py depending on whether you downloaded any datasets. If you are running an X-server or if you have the error Aborted (core dumped), see this issue. Wiki How it all works (WIP - stub, you might be better off reading my thesis until it's done) Training models yourself Training with other data/languages (WIP - see here for now) TODO and planned features Contribution Feel free to open issues or PRs for any problem you may encounter, typos that you see or aspects that are confusing. I try to reply to every issue. I'm working full-time as of June 2019. I won't be making progress of my own on this repo, but I will still gladly merge PRs and accept contributions to the wiki. Don't hesitate to send me an email if you wish to contribute. Sursa: https://github.com/CorentinJ/Real-Time-Voice-Cloning 5 Quote
