One audiovisual foundation model that sees, hears, reasons, speaks and expresses at the same time — built by the ex-Apple team behind Vision Pro’s Digital Persona.
Nuance Labs is a Seattle AI research lab building a single foundation model for human conversation and expression. Today's face-to-face AI is assembled from parts — speech is transcribed, a language model decides what to say, a voice reads it out and a face is animated to match — and the company argues that everything human about a conversation is lost in those handoffs, leaving avatars that sit frozen, talk over you, or lag. Its model instead perceives and responds in one system, reading words, tone, gaze, gesture and timing and answering in kind, running full-duplex so it can show it is following before you finish speaking. The founders — Fangchang Ma, Edward Zhang and Karren Yang — came from Apple, where Ma and Zhang worked on the Vision Pro's Digital Persona system.

A single full-duplex audiovisual foundation model for human conversation and expression: it streams perception in and response out at the same time, reading words, tone, gaze, gesture and timing together and answering with matching facial and vocal expression, instead of chaining transcription, an LLM, text-to-speech and face animation. The company says this is what removes the lag and the frozen-avatar effect that make face-to-face AI feel uncanny.
Real-time emotion generation — avatars that coordinate facial expression, vocal inflection and body language into an appropriate response
Real-time emotion reading — live coaching and interview systems that pick up how something is said, not only what is said
Public research preview of the model, planned for later in 2026
