What are Coqui TTS and GPT-SoVITS?

Coqui TTS

Coqui TTS is a library and toolkit for advanced text-to-speech generation, including voice cloning with the XTTS model. It supports many languages and pretrained voices for fully local speech synthesis.

  • Multilingual synthesis
  • XTTS voice cloning
  • Many pretrained models
  • Trainable on custom data

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

Coqui TTS vs GPT-SoVITS: key differences

Both projects are written in Python. Licensing differs — MPL-2.0 for Coqui TTS versus MIT for GPT-SoVITS. Coqui TTS is the more established project (first released 2021), while GPT-SoVITS arrived in 2024.
