Nuance Labs raises $50M to build low-latency conversational AI avatars

Three ex-Apple researchers secure Series A funding from Lightspeed, Accel, and Nvidia to develop AI that handles face-to-face conversations without lag.

What to know

  • Nuance Labs secured $50 million Series A led by Lightspeed to build AI conversational avatars that operate without the latency and awkwardness of existing chatbots.
  • The startup's technical approach differs from competitors by using a single unified model with integrated audio-video processing, rather than stitching together separate voice-to-text, language model, and text-to-voice systems.
  • Founded by three ex-Apple researchers, Nuance is pre-product but plans to launch a research preview in late 2026, targeting use cases in interview prep, language learning, and enterprise customer support.
  • The company emphasizes collecting bespoke audiovisual training data from real conversations rather than internet scraping to preserve natural human nuances like microexpressions and natural reactions.

“The perfect data for us will be, imagine the two of us having this conversation, we're having to record it. I want audiovisual from both sides. Both participants are visible, soundtracks cleanly separated, and then it's also natural, not performative.”
