model fieldKokoro is a lightweight, open-weight TTS model — just 82 million parameters on a decoder-only StyleTTS2 + ISTFTNet architecture, no diffusion. Despite its size it delivers quality comparable to much larger TTS models while running significantly faster and cheaper, with 54 voices across 8 languages. Trained exclusively on permissive, non-copyrighted audio. Apache 2.0.
