Open-source State-of-the-art TTS model which runs on a CPU 😻

CPU-only TTS with voice cloning from a 1.7B 1-bit model — KittenTTS 2 is a 1.7B-parameter 1-bit speech model offering in-context voice cloning from just five seconds of audio plus expression control, running realtime on CPU. Legacy 15M-80M models remain available through the same constructor for lightweight, GPU-free deployments.
