Behavioral Signals - The Team

What We Do

We are bridging the communication gap between humans and machines by introducing emotional intelligence, from speech, into conversations with AI. We have created the fastest evolving and most robust emotion AI, enabling everyone to add emotion and behavioral recognition to their own software solutions, through the Oliver API. Whether it’s for a virtual assistant on a mobile phone, on the web, in a car, on a smart speaker, or for a social robot, an interactive child’s toy, a robotic carer, companies, developers or DIY enthusiasts can now design and build engaging interactions which can seamlessly benefit from our internationally acclaimed speech emotion recognition technology. Our production-level Oliver ΑPI, offers a rich variety of emotional and behavioral metrics and allows both real-time and batch audio processing, and can readily support heavy-duty applications.

Our Founders

Driven by a passion to bring our ground-breaking patented speech-to-emotion and speech-to-behaviors technologies to market, Professors and Scientists, Alex Potamianos and Shri Narayanan founded Behavioral Signals in 2016. With the goal of enhancing and forever changing the world of business, technology is at the core of what we do. Our algorithms analyze human emotions and behaviors, transform data into usable information, and lead to making better business decisions and increasing profits. Until now, human emotion has been considered impossible to quantify, and impossible to measure. With our patented analytics engine, we use science to measure and interpret the “how” part of human interactions.

“Artificial intelligence is helping businesses create experiences that naturally integrate with consumers’ everyday lives. Human communication is a complex process that depends on the words being spoken, as well as the way they are being expressed. We understand not only what is being said but how it is being said, the emotions, intentions, state-of-mind and behaviors of each person. I’m extremely optimistic about our potential.”
