One of the core features of KittenTTS is that it runs completely offline. On first use, the model downloads the weights from Hugging Face and caches them locally, eliminating the need for an Internet connection for subsequent speech generation. This feature is especially suitable for applications in network-less environments (e.g., remote areas or privacy-sensitive areas), ensuring data privacy while providing stable speech synthesis services. In addition, the small size of the model (25MB) and its fast generation capability (e.g., 19 seconds to generate 26 seconds of audio on an M1 Mac) further enhance its usefulness in offline scenarios.
