What are GPT-SoVITS and openedai-speech?
GPT-SoVITS
GPT-SoVITS is an open-source voice conversion and text-to-speech system capable of cloning a voice from a very short audio sample. It can be self-hosted with a web UI for training and generating speech in multiple languages.
- Few-shot voice cloning
- Multilingual synthesis
- Web training UI
- Runs locally
openedai-speech
openedai-speech is a self-hosted text-to-speech server that mimics the OpenAI audio speech API. It uses local models such as Piper and Coqui XTTS to generate audio without sending data to the cloud.
- OpenAI speech API compatible
- Piper and XTTS backends
- Custom voice mapping
- Drop-in replacement
GPT-SoVITS vs openedai-speech: key differences
The biggest difference is maintenance: openedai-speech's repository is archived and no longer developed, while GPT-SoVITS is actively maintained. Both projects are written in Python. Licensing differs — MIT for GPT-SoVITS versus AGPL-3.0 for openedai-speech. Openedai-speech is the lighter option, starting around 2,048 MB of RAM against 4,096 MB for GPT-SoVITS. GPT-SoVITS has the considerably larger community, at 62,097 GitHub stars versus 857.
