What it is
Amphion is a Python toolkit for generating audio, including speech, singing voice, and sound from text. It bundles several models (such as MaskGCT and Vevo), vocoders, datasets, and evaluation metrics in one codebase. The project aims to support reproducible research and help newcomers learn how these systems work, and it includes visualizations of classic model architectures.
- Run text-to-speech or voice conversion experiments using the models listed in the README
- Compare evaluation metrics across audio generation outputs
- Study model architectures through the project's visualizations
- Build or curate large-scale speech datasets using the dataset tooling referenced in the README
Great for
- Researchers who want reproducible implementations of speech and audio generation models
- Junior engineers learning how text-to-speech or voice conversion systems are built
- Teams experimenting with zero-shot voice cloning or voice conversion
- People who need vocoders or evaluation metrics for audio generation work
Not ideal for
- People who just want a finished voice app with no setup, since the README describes a research toolkit rather than an end-user product
- Users without a Python and deep-learning environment, because the project requires running code and models locally
- Projects needing production-grade guarantees, since the latest release is labeled v0.1.1-alpha
How to get it
- 1
Clone and build from source
You'll need: Python · Git
Clone the repository
git clone https://github.com/open-mmlab/Amphion.git - 2
Run it
- Clone the repository and open the folder.
- Read the README section for the task you want (for example the TTS or SVC guide linked from the README badges).
- Follow the environment and model setup instructions in that task's README.
- Run the example recipe for that task and check the output audio.
- 3
Get the most out of it
- Start from the task-specific READMEs linked in the top badges (TTS, VC, SVC, TTA, Vocoder, Evaluation).
- Use the pre-trained models published on Hugging Face or ModelScope, as linked in the README.
- Try the visualizations of classic architectures to understand models before modifying them.
- Join the Discord community linked in the README for questions and updates.
Downloads
Strengths
- Covers many tasks (TTS, SVS, VC, SVC, TTA, vocoders, evaluation) in one toolkit
- Released under the MIT license and actively updated, with the last push in March 2026
- Aims explicitly at education and reproducibility, with architecture visualizations
Trade-offs
- Latest release is an alpha version (v0.1.1-alpha) with no binaries, so expect rough edges
- Several models and datasets have different licenses; for example, part of Emilia is CC BY-NC 4.0
- Text-to-music is listed as still in development in the README
