RELLEN - born out of the science behind conversation

At RELLEN we combine cognitive science expertise with machine learning solutions to interpret conversation beyond its verbal content.

We have developed the first-of-its-kind facial movement analysis software SecretSight™. SecretSight™ is RELLEN’s computer-vision interview intelligence tool for real-time detection of markers of unreliable conversation with greater than 90% ACCURACY*. Whether these unreliable moments are due to issues with recall, misunderstanding, withholding or misinformation; SecretSight™ ensures these moments are not missed and left unresolved.

Scientific understanding that we can actually map and model facial movements that are as tied to the message of the dialogue as the speech itself is new discovery and it’s a field that is growing quickly. We apply this to provide solutions for industry.

This is a new discovery and it’s a field that is growing quickly.

*Performance measured through internal validation with expert review and synthetic test scenarios.
*The tool is designed for decision-support only and is not intended for standalone evidentiary conclusions.
