LVA™ Technology

Company: Nemesysco
Details :

 

Layered Voice Analysis (LVA™) is Nemesysco's core technology adapted to meet the needs of various security-related activities, ranging from formal police investigations to security clearances, from secured area access control to intelligence gathering and lawful interception multi-channel analysis.

 

In its essence, LVA technology enables better understanding of your suspect’s mental state and emotional makeup at a given moment by detecting the emotional cues in his or her speech. The technology identifies various types of stress levels, cognitive processes, and emotional reactions that are reflected in different properties of the voice. This information provides insights into the way the subject thinks, what troubles him, what excites him, what portions of his speech he is uncertain about, what questions require more of his attention, and what areas appear to be sensitive issues for the speaker.

 

LVA uses a unique mathematical process to detect different types of patterns and abnormalities in the speech flow and classify them in terms of stress, excitement, confusion and other relevant emotional states, found through our research to be highly correlated with these emotions.

 

LVA technology further enables the user to explore several levels of emotional intensity, and by doing so, expose additional layers of information that would otherwise be unavailable. This information can save crucial time during any investigation processes.

 

Nemesysco’s Layered Voice Analysis is a new and proprietary technology and has no relations to the old "Voice Stress Analysis” (or VSA) technologies, nor does it use any previously known method for detecting "voice stress". As such, LVA does not perform "micro-tremors" (8-14 Hz) analysis in the voice, and can be used over telephone lines and with standard commercially available microphones.
