About Tortoise TTS
Tortoise TTS is an open source text-to-speech program that converts text to speech with multiple voices. The repository contains code to run the system in inference mode, with pip, Conda, and Docker installation methods and command-line synthesis using voice and preset options.
Local use requires an NVIDIA GPU. The Hugging Face Spaces demo also requires a GPU and does not work on CPU-only Spaces, and the documentation notes low sampling rates from its autoregressive and diffusion decoders.
Key features
- Generates speech from text using multiple voices
- Runs locally in inference mode from repository code
- Installs with pip including option from git repository
- Provides Docker configuration for containerized setup
- Offers Hugging Face Spaces demo requiring GPU
- Supports command-line synthesis with voice and preset flags
