Best alternatives to KittenTTS in 2026
Good text-to-speech usually means either a cloud API that costs money per character, or a local model so large it needs an expensive GPU to run in real time. KittenTTS is built to avoid both: it's a small enough model — as little as 25MB — that it generates natural speech on a regular CPU, making it practical to embed directly into mobile apps, edge devices, or any service where a GPU isn't an option. KittenTTS is an Apache 2.0-licensed, ONNX-based text-to-speech library optimized for CPU inference, with models ranging from 15M to 80M parameters (25-80MB on disk). It ships with 8 built-in voices (Bella, Jasper, Luna, Bruno, Rosie, Hugo, Kiki, Leo), 24kHz output, adjustable speech rate, and text normalization for abbreviations, dates, and other special formatting. With 15,200+ GitHub stars, it's one of the more popular lightweight TTS projects, and commercial support plus custom voice development are available for teams that need it.
