E2 TTS

huggingface.co·Infrastructure

E2-TTS is a fully non-autoregressive zero-shot text-to-speech model developed as part of the F5-TTS project. It is trained on the Emilia dataset and provides high-quality speech synthesis. The model can be used locally with provided checkpoints and is accompanied by a research paper detailing its embarrassingly easy approach to TTS.
