5.6x realtime on CPU with voice cloning beats most local TTS options.
Kokoro voice cloning with multilingual support, but voice cloning itself is crowded.
Shrinks the usual TTS bloat into a 16MB Electron-alternative wrapper while still letting you clone voices from a short sample and 'design' voices from text prompts. It handles model downloads for you, supports batch exports and macOS auto-updates — smart product trade-offs. Caveat: the app binary is tiny, but the underlying TTS models are downloaded on demand, so expect large model pulls behind the scenes.
Another voice cloning platform when ElevenLabs already dominates this space.
