Open-source OmniVoice TTS server: 0.3s latency on RTX 3080, OpenAI-compatible API

Reddit user Delicious-Farmer-234 open-sourced a TTS server built on OmniVoice with an OpenAI-compatible API that generates a sentence in about 0.3 seconds on an RTX 3080 and can clone a voice from a short reference clip.

The server is optimized for fast generation start and processes long text paragraph by paragraph. The author uses it to turn school books into audiobooks in their own voice for listening while driving. Settings are pre-tuned but adjustable (e.g., CFG guidance scale).

Free and open source: repo at hypersniper05/open-omnivoice-tts, with a demo page for previewing all voices.
