canberkkkkkk · ema-lightning

**Tiny, fast and accurate Turkish text to speech.** A 5.6M-parameter DiT acoustic model and a 3M-parameter vocoder: 8.6M in total, about 34 MB. Apache 2.0. - **Most accurate on Freya-TR-Eval:** 0.92% WER, the lowest of every system measured, including ElevenLabs v4, Gemini 3.8 and the 2.38B-parameter Trendyol-TTS. - **Fast:** first audio in 3.86 ms and 440× faster than real time on an RTX 4090; 1,316× with batching. - **Streams:** audio starts while the rest of the text is still being generated. - **Cheap:** about $0.0085 per million characters on a rented RTX 4090. - **Runs anywhere:** GPU or CPU, fully offline. No API key, and no text or audio leaves the machine. - **One model serves many callers:** call it from as many threads as you like; its scheduler, Playhead, runs everyone's work together on the GPU. - **Code:** [EMA Lightning on GitHub][github] - **Package:** `pip install ema-lightning` - **Text frontend:** normalizer-tr, by Erdem Tuna

Frequently asked questions

Do open weights permit free commercial use?

Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.

Are these real-time billing prices?

These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
