# Real-Time Voice Cloning

This repository is an implementation of [Transfer Learning from Speaker Verification to
Multispeaker Text-To-Speech Synthesis](https://arxiv.org/pdf/1806.04558.pdf) (SV2TTS) with a vocoder that works in real-time. This was my [master's thesis](https://matheo.uliege.be/handle/2268.2/6801).

SV2TTS is a deep learning framework in three stages. In the first stage, one creates a digital representation of a voice from a few seconds of audio. In the second and third stages, this representation is used as reference to generate speech given arbitrary text.

## Heads up

Like everything else in Deep Learning, this repo has quickly gotten old. Many SaaS apps (often paying) will give you a better audio quality than this repository will. If you wish for an open-source solution with a high voice quality:

- Check out [paperswithcode](https://paperswithcode.com/task/speech-synthesis/) for other repositories and recent research in the field of speech synthesis.
- Check out [Chatterbox](https://github.com/resemble-ai/chatterbox) for a similar project up to date with the 2025 SOTA in voice cloning

## Running the toolbox

Both Windows and Linux are supported.
1. Install [ffmpeg](https://ffmpeg.org/download.html#get-packages). This is necessary for reading audio files. Check if it's installed by running in a command line
```
ffmpeg
```
2. Install uv for python package management
```
# On Windows:
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
# On Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Alternatively, on any platform if you have pip installed you can do
pip install -U uv
```
3. Run one of the following commands
```
# Run the toolbox if you have an NVIDIA GPU
uv run --extra cuda demo_toolbox.py
# Use this if you don't
uv run --extra cpu demo_toolbox.py

# Run in command line if you don't want the GUI
uv run --extra cuda demo_cli.py
uv run --extra cpu demo_cli.py
```
Uv will automatically create a .venv directory for you with an appropriate python environment. [Open an issue](https://github.com/CorentinJ/Real-Time-Voice-Cloning/issues) if this fails for you

### (Optional) Download Pretrained Models

Pretrained models are now downloaded automatically. If this doesn't work for you, you can manually download them from [Hugging Face](https://huggingface.co/CorentinJ/SV2TTS/tree/main).

### (Optional) Download Datasets

For playing with the toolbox alone, I only recommend downloading [`LibriSpeech/train-clean-100`](https://www.openslr.org/resources/12/train-clean-100.tar.gz). 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](https://github.com/CorentinJ/Real-Time-Voice-Cloning/wiki/Training#datasets). 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.
