Polygraph Alternative: Explore VIPRE AISIS and VASIS

A different approach to the investigative interview

For agencies considering a polygraph alternative, VIPRE offers two portable systems built around voice stress analysis. AISIS and VASIS capture speech through a microphone for review by trained investigative professionals. They provide a different examination workflow from a polygraph, which records bodily responses through attached sensors.

The right starting point is your operational requirement: where examinations take place, how questions are prepared, who reviews the record, and how findings inform follow-up. Evaluate VIPRE against those requirements rather than assuming that different methods produce interchangeable results.

AISIS: AI-assisted analysis with examiner control

AISIS combines AI-assisted stress classification with synchronized waveform, audio, and video review. An examiner can return to a recorded response and review the available material together, helping keep the question, answer, and interview context connected.

For teams evaluating how to document and review interviews, that connected record is a practical feature to assess during a demonstration. The examiner remains responsible for interpretation. AI assistance does not turn a stress indication into proof of deception.

VASIS: a focused examiner-led workflow

VASIS is a current VIPRE option for agencies seeking examiner-led voice stress analysis. Its portable configuration includes saved question templates, automatic microphone adjustment, live charting, and notes tied to individual responses.

Choose VASIS when its operating approach fits your team’s requirements. Compare the preparation, recording, chart review, and documentation steps with your existing procedures. A useful demonstration follows a realistic examination sequence so your examiners can assess the work they would actually perform.

Plan training around the system you will use

VIPRE offers Basic Examiner Certification and online training options. Prior polygraph experience can inform an examiner’s professional practice, but it should not be treated as automatic certification to operate a different system.

Before selecting equipment, confirm the training allocation, certification requirements, and support arrangements for your proposed package. Include the personnel who will conduct examinations and those responsible for reviewing their records.

Know what an alternative can and cannot establish

Neither polygraph nor voice stress analysis directly measures a lie. Stress-related responses require interpretation and can have explanations other than deception. An indicated response is a reason for closer review and independent follow-up, not a finding of guilt.

A demonstration can establish whether the workflow suits your team. It cannot establish a system’s accuracy. Ask for evidence relevant to the specific product, intended task, and population, and keep product features separate from performance claims. Introducing a different examination method also requires an agency review of its policies and permitted uses.

Evaluate VIPRE for your agency

Tell VIPRE what you need from a polygraph alternative: your examination setting, current experience, review requirements, and the number of examiners you plan to train. The discussion can then focus on AISIS or VASIS and the package that fits your operation.

• Review a demonstration with the examiners who will use the system.
• Compare recording, review, and documentation needs.
• Confirm certification, equipment, and support before purchase.
