Nuance Labs Raises $50M for Realistic AI Avatars

Seattle startup Nuance Labs has closed a $50 million Series A round led by Lightspeed Venture Partners, with participation from Accel, South Park Commons, Nvidia, and Define Ventures. The funding will accelerate development of its human foundation model designed to make AI avatars more natural and responsive. Unlike existing systems that chain together separate models, Nuance's full-duplex approach processes and responds to audio and video simultaneously, allowing avatars to react to speech, tone, gaze, and gestures in real time. Target use cases include sales, customer service, coaching, and education, with a public research preview expected later this year.
