F5-TTS is a local text-to-speech system for developers and creators generating speech on their own hardware. Its Gradio app provides a browser interface for speech generation, with tools for training and fine-tuning models.

  • Longer text: Generate speech in chunks to handle longer passages.
  • Speakers and styles: Combine multiple speakers or speaking styles in generated audio.
  • Voice chat: Use the Gradio app's voice conversation feature powered by Qwen2.5-3B-Instruct.
  • Custom models: Train or fine-tune through Gradio or Hugging Face Accelerate, with custom inference support for additional languages.

The Python code is open source under MIT. F5-TTS supports NVIDIA GPUs and Docker deployment, and provides a serving path using Triton and TensorRT-LLM.
