Layered Voice Analysis Technology (LVA) was invented in Israel in 1997, originally for security purposes. Today, Nemesysco technologies provide voice analysis solutions for both defense and civilian markets and based on emotion detection through voice analysis, optimize the processes of truth verification, expose malicious intentions, provide risk assessments and reveal emotions.
LVA is comprised of a set of unique signal processing algorithms that identify different types of stress, cognitive processes and emotional reactions. 129 vocal parameters are utilized in order to detect and measure minute, involuntary changes in the speech waveform and create the foundation for identifying the speaker’s emotional profile. Enabling analysis of conversations in real-time or offline (from recorded files) and providing quick truth verification, LVA makes investigators' work more efficient and improves decision making processes.
