Overview
Founded by former Apple PhD researchers Fangchang Ma, Edward Zhang, and Karren Yang, Nuance Labs is training a single full-duplex audiovisual model that perceives gaze, gesture, tone, and timing while streaming expressive responses in real time. A public research preview is planned later in 2026; intended use cases include sales, customer service, coaching, training, and education.
Why Nuance Labs is interesting
Nuance Labs raised a $50M Series A led by Lightspeed with Accel, NVIDIA, South Park Commons, and Define Ventures while still pre-public-product — betting that face-to-face AI fails because stacked STT→LLM→TTS→avatar pipelines lose timing and expression, not because the demos look bad.
Product & use cases
A specialized full-duplex foundation model for human conversation and expression that streams audiovisual perception and response simultaneously instead of chaining separate speech, language, and animation systems.
- Real-time face-to-face AI for sales and customer service
- Coaching, professional training, and education avatars
- Any product where expressive back-and-forth is the interface, not a chatbot transcript
