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.
