How is this computed?

round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10) — computed 2026-09-02. Adoption (stars, forks) is never an input.

MegaTTS 3 is ByteDance's open-source PyTorch text-to-speech model with a lightweight 0.45B-parameter Diffusion Transformer backbone. It provides high-quality zero-shot voice cloning with bilingual Chinese/English support and code-switching.

Use cases

  • clone a voice from a short audio sample
  • generate speech from text in Chinese and English
  • build a TTS pipeline with a lightweight model
  • control accent intensity in synthesized speech
  • synthesize code-switched Chinese-English speech

When to choose

  • you need high-quality zero-shot voice cloning
  • you need bilingual Chinese/English TTS with code-switching
  • you want a research-grade TTS model under an Apache-2.0 license

When to avoid

  • you need production TTS on Windows or macOS without extra setup
  • you need many languages beyond Chinese and English
  • you need fine-grained pronunciation/duration control, which is not yet implemented
