// como funciona

Como funciona

  1. Choose SVS or TTS

    Decide whether you want singing synthesis (lyrics + F0 or MIDI input) or the DiffSpeech text-to-speech variant.

  2. Clone and set up the environment

    Clone the repo and create the documented Conda or venv environment for your GPU/CUDA version.

  3. Install dependencies

    Install the requirements file matching your hardware, as listed in the README.

  4. Run inference

    Download a checkpoint, follow the SVS or TTS document, and synthesize your first utterance or song line.

Por que as pessoas gostam tanto

Shallow diffusion mechanism

The paper's core contribution: diffusion applied at a shallow stage for faster, high-quality mel-spectrogram generation.

Singing voice synthesis

Generate singing from lyrics with ground-truth F0, or from lyrics + MIDI with explicit F0 prediction, on PopCS/OpenCpop pipelines.

DiffSpeech TTS included

A text-to-speech variant in the same framework, trained on LJSpeech with a HiFiGAN vocoder.

PNDM acceleration plug-in

Optional DiffSinger-PN adds the PNDM sampler to speed up diffusion sampling.

Multiple vocoders

NSF-HiFiGAN for singing pipelines and HiFiGAN for TTS, per the README's pipeline table.

Training and inference code

Full official code with documented SVS/TTS run guides and TensorBoard logging, not just a demo.

Execute você mesmo

  1. Clone the repository

    Clone the project and enter its directory.

    git clone https://github.com/MoonInTheRiver/DiffSinger.git
    cd DiffSinger
  2. Create the environment

    Create and activate a Python 3.8 Conda environment as documented.

    conda create -n your_env_name python=3.8
    conda activate your_env_name
  3. Install requirements for your GPU

    Pick the requirements file matching your GPU/CUDA (2080Ti/CUDA 10.2 or 3090/CUDA 11.4 examples in the README), then follow the SVS/TTS docs to run inference.

    pip install -r requirements_3090.txt  # or requirements_2080.txt — see README

// perguntas frequentes

Perguntas frequentes

Who maintains DiffSinger?

It is the authors' official repository (MoonInTheRiver), with later maintenance help noted from Team Openvpi; the paper appeared at AAAI 2022.

Is DiffSinger free?

Yes, the code is MIT-licensed. Pretrained checkpoints and datasets (PopCS, OpenCpop, LJSpeech) have their own terms — check each before commercial use.

Does it need a paid API key?

No. Everything runs locally on your own GPU; there is no hosted API involved.

How does it compare to later tools like OpenVPI's DiffSinger fork?

This is the original research implementation the community forks build on; forks such as OpenVPI's add newer editors and workflows, while this repo remains the reference for the paper's method.

How do I get started?

Clone the repo, create the Python 3.8 environment from the README, install the requirements file for your GPU, then follow the linked 'Run DiffSinger (SVS)' or 'Run DiffSpeech (TTS)' document.
