VASIS: Voice Stress Analysis Identification System
The VASIS Field Unit is a next-generation Voice Stress Analysis platform engineered for law enforcement, security agencies, and investigative professionals who require precise, real-time assessment of autonomic stress indicators. Built on validated vagal-response science and supported by IAVSA-recognized testing protocols, VASIS provides examiners with a reliable, objective, and highly efficient tool for evaluating stress during interviews, screenings, and investigative procedures.
Designed for mobility, accuracy, and operational consistency, VASIS combines intelligent automation, advanced acoustic capture, and intuitive workflows to ensure examiners can focus on interviewing—not equipment setup. Whether used in field environments, interrogation rooms, or internal affairs settings, VASIS delivers standardized, data-driven results that improve decision-making and enhance investigative outcomes.
System Architecture & Core Capabilities
Powered by Lenovo IdeaPad Performance
VASIS operates on a Lenovo IdeaPad 14–15.6-inch touchscreen laptop equipped with 16 GB RAM, a 512 GB solid-state drive, and the VIPRE specialized microphone—optimized for field and investigative performance.
Engineered for Ease and Mobility
Built from the ground up for law-enforcement and investigative professionals, VASIS offers unsurpassed usability and mobility in any environment. Its auto-calibrating microphone, intuitive menu system, and pre-built templates minimize setup time—so you can focus on interviewing, evaluating, and documenting results.
Intelligent Automation
VIPRE automatically generates the correct examination format based on the number of relevant questions, ensuring compliance with professional testing standards. Create and save category-based templates for pre-employment, investigative, or internal affairs scenarios—ready to recall in seconds.
Integrated Stress Analysis with VASIS
VASIS (Voice Stress Analysis Identification System) to instantly identify stress-related vocal patterns:
-
Black Pattern = NSI (No Stress Indicated)
-
Red Pattern = SI (Stress Indicated)
This color-coded analysis delivers real-time pattern recognition and decision support during every examination.
Rapid Start
The system launches with only six prompted data questions, automatically identifying the examiner and test subject while initiating the auto-test generation sequence—no manual modulation or voice sampling required.
Auto-Calibration
VIPRE’s automatic gain control and advanced sound-capture technology eliminate traditional calibration routines. Examiners can begin testing without repeated sample recordings or manual modulation adjustments.
Consistent Pattern Quality Control
Built-in auto-sizing graphics ensure consistent voice pattern quality and faster exam completion. The VIPRE digital microphone and custom lanyard maintain acoustic integrity across all sessions, aligned with IAVSA-recognized testing protocols.
Automatic Test Format Creation
Simply select the number of relevant questions, and VIPRE creates a compliant test sequence with the appropriate mix of relevant, control, and irrelevant questions—removing guesswork and ensuring consistency.
On-Screen Pre-Examination Review
Before testing, easily review and confirm each question using the on-screen checklist, capturing the subject’s pre-test responses with a single click.
Comprehensive Real-Time Monitoring
During the live exam, patterns appear in real time along the screen’s lower display, automatically compiling a complete chart as each question is asked. Examiners can:
-
Accept or reject individual voice patterns
-
Add on-screen notes under each pattern
-
Seamlessly transition between charts
-
Store, print, or email completed exams for evaluation
