About this product
Hlas-1 is a 3.5B open-weight text-to-speech model that whispers, laughs, cries, and follows custom emotion and pacing instructions. Shape delivery with inline tags, clone a voice from a short reference clip, and generate multilingual speech. Built as a spare-time project on Breeze TTS 2, with 24 kHz audio and a streaming runtime. Free for research and non-commercial use.
