KittenML (Stellon Labs) · Voice Cloning TTS

KittenTTS 2

A 1.7B speech language model that writes codec tokens a vocoder turns into 24 kHz audio, a new model from the team behind the small KittenTTS (week 8). It clones a voice from 5 to 30 seconds of one speaker and ships 47 built-in voices, nine of them carrying Arabic, Chinese, French, German, Hindi, Italian, Portuguese, Russian and Spanish, with beta tags for ten emotions, ten vocal events such as laughs and sighs, and emphasis. The default weights are packed as 1.58-bit ternary (954 MB) and produce audio bit-identical to the 3.47 GB bf16 file, with GGUF files and a llama.cpp fork for CPU use.
