It allows conditioning on audio for emotion and tone control and can produce nonverbal communications. Pretrained model checkpoints and inference code are available on Hugging Face, and there is a demo comparing it with ElevenLabs Studio and Sesame CSM-1B. The model runs on GPUs with future support for CPUs and comes with detailed installation instructions. Ethical and legal guidelines are provided for its use. ## Full article daily.dev links to this article rather than hosting it.
