VASIS™ is a voice-based, question-driven stress identification platform designed for use by law enforcement, security agencies, and investigative professionals. The system assists trained examiners in identifying relative autonomic stress indicators associated with specific questions during structured interviews, screenings, and investigative procedures.

VASIS does not determine truth or deception and is not a lie detector. The system functions as an investigative support tool that provides stress-related indicators requiring interpretation by qualified examiners within the context of a complete investigation.

​

Built on established vagal-response research and structured testing protocols, VASIS applies examiner-guided analytical methods to support consistent evaluation of vocal stress responses. The system does not rely on population norms or automated truth scoring and does not produce conclusions independent of examiner judgment.

 

Designed for operational reliability and field mobility, VASIS integrates advanced acoustic capture, intelligent automation, and streamlined workflows that allow examiners to focus on structured questioning and professional assessment rather than equipment operation.

​

Used in investigative interviews, screening environments, and administrative inquiries, VASIS supports consistent analytical review while maintaining the examiner as the final interpretive authority. All outputs are advisory indicators intended to assist investigative focus and follow-up strategy.

System Architecture & Core Capabilities

​

Powered by Lenovo IdeaPad Performance

VASIS operates on a Lenovo IdeaPad 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
