Shared compatibility

  • Python · TTS: Python runtime · vall-e: Python runtime

Choose TTS if…

  • License: TTS is MPL-2.0, vall-e is Apache-2.0.
  • Tags unique to TTS: deep-learning, glow-tts, hifigan, melgan.
  • TTS ships Docker support for self-hosted deployment.
  • If you are working on research projects that require advanced models such as Glow-TTS, HifiGAN, or MelGAN for high-quality speech synthesis

When NOT to use TTS

  • If your project strictly requires a lightweight installation without the overhead of extra dependencies included when installing 🐸TTS from source for development purposes
  • In cases where you are restricted to older Python versions less than 3.9, as 🐸TTS is tested on systems with python >= 3.9 but < 3.12

Choose vall-e if…

  • License: vall-e is Apache-2.0, TTS is MPL-2.0.
  • Tags unique to vall-e: chatgpt, in-context-learning, large-language-models, text-to-speech.
  • When you require high-fidelity speech synthesis that does not require prior training on specific voices

When NOT to use vall-e

  • If your project demands real-time processing, as VALL-E's performance may be slow due to its complex model architecture
  • When limited computational resources are available, as the tool relies on PyTorch and substantial compute power for inference
