About KittenTTS
KittenTTS is an open-source, ultra-lightweight text-to-speech library with models ranging from 15M to 80M parameters (under 25MB on disk) that runs entirely on CPU — no GPU required. It delivers real-time speech synthesis in multiple voices (Bella, Jasper, Luna, Bruno, and others) with adjustable speed, supports deployment on mobile, Raspberry Pi, edge devices, and lightweight servers, and is accessible via a Hugging Face Spaces demo or self-hosted API server. It is a practical choice for developers who need privacy-preserving, on-device TTS in resource-constrained environments such as IoT or embedded applications.
