Once a talking face can hold a live conversation, timing matters more than how real it looks.
Nuance Labs launched Emma, an AI video persona whose reply timing matched real human speakers 89% of the time.
She runs on Nuplex 1.0, a full-duplex audiovisual model that listens and speaks at once, so her face reacts while you’re still talking.
A very interesting part is that Emma’s face and voice come from a real actress who worked with Nuance Labs to record how she actually listens, reacts and speaks, then fed into their Nuplex model.
The result is a set of mannerisms that belong to one character.
A long blink for emphasis.
A squint.
Eyes that drift away and come back.
A small jump when she can’t hold back how strongly she feels.
A head that moves with the sentence.
