Nuance Labs is a Seattle AI lab building what it calls a human foundation model: a multimodal model that ingests text, speech, facial expression and body language in real time and responds with expressive speech and video. The model compresses human video into tokens and extends LLM-style autoregressive prediction to audio and visual modalities, so an agent can detect fine-grained emotion, expression and gesture on a live video stream. The company was founded by Fangchang Ma and Edward Zhang, both former Apple researchers who worked on the Apple Vision Pro Digital Persona, and raised a $10M seed led by Accel with Lightspeed and South Park Commons participating.
