Kitten TTS: Ultra-Efficient AI Text-to-Speech Model for On-Device Voice Synthesis

What Is Kitten TTS and Why It Matters? In the world of AI voice synthesis, the prevailing narrative has been “bigger is better.” Multi-billion-parameter models deliver life-like speech—but only if you have a GPU farm and an AWS budget to match. Kitten TTS flips that script. At just 15 million parameters and under 25 MB on disk, this open-source, Apache 2.0-licensed model delivers expressive, high-quality voices without a GPU—on everything from your laptop to a Raspberry Pi, or even a smartphone. Kitten TTS isn’t about chasing benchmarks; it’s about democratizing voice AI. By slashing resource requirements, it puts advanced text-to-speech …
