KittenTTS
KittenTTS is an ultra-lightweight open-source text-to-speech model that converts written text into natural-sounding speech with impressive quality while requiring minimal computing resources. Unlike most AI speech models that demand powerful hardware, KittenTTS runs efficiently on almost any device including older computers, Raspberry Pis, and even in browsers thanks to its tiny 25MB footprint and 15 million parameter design. The AI model delivers multiple realistic voices in real-time without requiring internet connectivity or GPUs, making it ideal for developers creating privacy-focused applications, edge computing projects, accessibility tools, or any scenario where resource efficiency matters. With its combination of high-quality output, remarkable speed on CPU-only systems, and open-source Apache 2.0 license, KittenTTS represents a breakthrough for deploying voice AI in resource-constrained environments where larger models simply cannot operate.
