There are moments in life when everything looks ordinary, yet something stirs beneath the surface. A conversation. A pause. A word that should mean nothing, but does. These moments don’t show up on charts. They don’t always have language. But you feel them.
That’s where Emotion Logic begins, not with what’s said, but with what’s felt and hidden.
We’ve spent decades refining a technology that listens for those hidden truths. It began as a quest to understand deception for security use cases, that was the only goal in mind. But very early on, we realized the real power wasn’t just in catching lies, it was in helping people confront their own internal emotional logic and conflicts.
We used Layered Voice Analysis not just to study people, but to reveal them to themselves. And some of the early stories are still hard to believe, even for me.
One of the first moments I remember was when a journalist came to interview me and test the system for a media segment. I asked her about different aspects of her life, and she responded with confidence. Then I asked her about children. She replied, “Never wanted them!” But the system showed a very different, unexpected reaction. When I turned the screen for her to see, she asked to stop the test. She looked at the textual result, clearly marked “False Statement”, paused, and quietly said, “Close it. I’ve always wanted a child. But I never really admitted it out loud. Until now.” A year later, she called me. Her daughter had been born.
In those early days, we saw results that defied expectations, and maybe even our own logic. Gamblers, addicts, and trauma survivors used their own voice as a kind of mirror. Not to uncover guilt or pain, but to recognize conflict, desire, or freedom. One therapist told us that after using the system with a patient who had carried a self-blame pattern for years, something finally clicked. “You just unlocked ten years of work in ten minutes,” she said.
That’s when I understood: this wasn’t just about machines understanding people. It was about people finally understanding themselves.
Emotion Logic doesn’t decode words, accents, or tone to identify emotional signs. It measures involuntary bio-markers, tiny vocal changes that occur when the emotional brain is active. Stress, excitement, anticipation, confidence, suppression, doubt. All identified without content, yet mapped to each and every word for contextual understanding. Pure physiology. That’s what makes it universal. Like a microscope pointed at the emotional dimension of psychology.
Our systems have been used in high-stakes investigations, mental health interventions, compliance protocols, and customer experience research. But no matter the context, it always comes back to the same principle: truth lives beneath the words. And when consequences matter, emotions speak louder than words.
What continues to surprise me, after all these years, is how often people discover something unexpected about themselves. A conflict they’ve buried or a fear they’ve normalized. A hope they thought they’d outgrown.
In the early days, people called it a lie detector. But today, I think of it as so much more, it’s an emotion compass. Something that doesn’t just catch you off guard, but helps you course-correct.
At Emotion Logic, we believe logic and emotion aren’t opposites. They’re reflections. They need each other to make sense of anything that truly matters.
And if you listen closely, beyond the noise, past the story, through the voice – you’ll often find that the most logical thing in the room, the one that creates its own reality… is your own feeling.
