⚠️ WORK IN PROGRESS: This model is still in early training stages. Current checkpoints produce low-quality, garbled speech. Updated checkpoints will be released as training progresses.

OpenF5-TTS

A commercial-friendly version of F5-TTS retrained from scratch on permissively-licensed data.

Trained on the Emilia-YODAS (CC-BY) dataset using the F5-TTS Small configuration.

GitHub Repository + Details

Usage

The model requires specific configuration files to work properly:

pip install f5-tts
huggingface-cli download mrfakename/OpenF5-Intermediate --local-dir openf5
f5-tts_infer-cli -mc openf5/model_config.yaml -p openf5/model_last.pt -v openf5/vocab.txt

Training Progress

Listen to various audio samples across steps. All samples use this text:

I don't really care what you call me. I've been a silent spectator, watching species evolve, empires rise and fall. But always remember, I am mighty and enduring.
