Raon-OpenTTS-1B

Catalogue summary: Open-weight and open-data English zero-shot TTS model based on the F5-TTS diffusion transformer architecture. The 1.048B parameter checkpoint supports voice cloning from reference audio, ships official PyTorch weights and code, and uses a 16 kHz HiFi-GAN vocoder path documented by KRAFTON.
