Nuance Labs launches Emma, a full-duplex AI persona, and a Nuplex Beta API
Nuance Labs released Emma, an AI persona built on its Nuplex 1.0 full-duplex audiovisual model, on Nov 9, along with a Nuplex Beta API for building custom personas. Nuance says Nuplex matched human reply timing 89% of the time across 1,785 questions (company-reported, not independently verified). Emma's face and voice are licensed from a real actress; the beta is limited to adults and English and prohibits unauthorized cloning of real people's faces and voices.
Nuance Labs released Emma on November 9, 2026. Emma is an AI persona that runs on Nuplex 1.0, a full-duplex audiovisual model that listens and speaks at the same time while generating facial expressions and eye movements. Emma's face and voice are licensed from a real actress who worked with the company during development.
Nuance also launched the Nuplex Beta API, which lets developers build customized AI personas and connect them to external tools. Nuance says Nuplex matched human reply timing 89% of the time across 1,785 questions, versus 35% for the next closest system; the company reported this itself and it has not been independently verified. Emma and the API are limited to adults aged 18 and over and to English. The beta excludes healthcare and education and prohibits unauthorized cloning of real people's faces and voices, and API-generated video carries a visible watermark. Availability is listed for the US (excluding Colorado, Connecticut, Illinois and Texas), the EU, the UK and Canada (excluding Quebec). Nuance acknowledges interruptions, visual misunderstandings, occasional facial glitches and incorrect answers.
