Kokoro voice cloning with multilingual support, but voice cloning itself is crowded.
5.6x realtime on CPU with voice cloning beats most local TTS options.
Qwen3-TTS voice cloning without finetuning in ~1 second on RTX 5070.
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.
Free local CharacterAI with voice cloning under 10s audio, plus ESP32 hardware integration.
Voice cloning on ESP32 without cloud beats Yoto's subscription model completely.
