Nuance Labs

What is Nuance Labs?

Nuance Labs is a Seattle-based AI company building a human foundation model for face-to-face conversation. The model is designed as one full-duplex system that sees, hears, reasons, speaks and expresses at the same time, rather than taking turns. It aims to read tone, expression and hesitation and respond in real time, with natural-looking speech and video, active listening cues such as nodding and interjections, and a warm personality. The company describes a conversation latency floor of 500 milliseconds. At the moment the product is a research preview: visitors can join a waitlist to talk with the company's avatar. The site publishes no pricing, platform list or API information, so check the site for updates on access.
