Voice Stress Analysis Software for Investigative Teams

Software should support the examination, not replace it

Voice stress analysis software belongs inside a disciplined investigative process. It can help trained investigative professionals organize an examination record, review defined response segments, and identify material that may merit careful follow-up. It cannot determine truthfulness, deception, guilt, credibility, or a legal outcome.

That distinction matters at the point of purchase. A useful platform gives an examiner a clearer way to prepare questions, capture usable material, document limitations, and preserve the basis for a later review. It does not turn a color, score, waveform, or stress indication into a conclusion about a person.

VIPRE offers AISIS and VASIS as two current options for agencies and examiners. Both keep the trained professional responsible for the interview, interpretation, report language, and investigative next step. The right choice depends on the work your team needs to perform and the record it needs to retain.

Start with the workflow your team must manage

Before evaluating features, define the assignments the software must support. A unit conducting internal investigations may need consistent question preparation, supervisory review, and an examination record that another qualified reviewer can understand. A field team may place greater weight on portable collection, clear audio, and practical controls that do not interrupt a structured interview.

Write down what must be prepared before the session, what must be captured during it, who reviews the record afterward, and what evidence will be used to corroborate a potential lead. Those answers are more useful than a generic feature list because they show whether a platform fits the agency's actual procedure.

The same review should identify the conditions that make an interpretation uncertain. Background noise, interruptions, overlapping speakers, unclear questions, fatigue, illness, trauma, language differences, and the pressure of an interview can all affect the record and its context. Responsible software should support clear documentation of those limits, not conceal them.

• Question preparation and pre-examination review
• Audio capture and a usable examination record
• Examiner notes, report language, and supervisory review
• Defined investigative follow-up and independent corroboration

AISIS: connected review for complex examination records

AISIS combines AI-assisted stress classification with synchronized waveform, audio, and video review in a portable examination environment. It is designed for teams that need to revisit a recorded response with the available context connected: the question, answer, audio, video, waveform display, and examiner notes.

AI-assisted classification can help organize material for review, but it does not remove examiner responsibility. The examiner controls question preparation, response acceptance, interpretation, follow-up questioning, and final reporting. A visible stress indication remains advisory information that must be considered alongside the complete interview and independently verified facts.

For a software evaluation, ask to see the complete workflow rather than an isolated screen. Review how a session is prepared, how the system handles unusable material, how notes and records are retained, and how a qualified supervisor can examine the work later.

VASIS: focused, examiner-led voice stress analysis

VASIS provides a focused voice stress analysis workflow for teams that want a portable, question-driven examination environment. Its microphone-based collection and examiner-controlled review are intended to keep attention on the structured interview while providing a clear record for assessment and follow-up.

VASIS is a current VIPRE system, not a legacy option. It supports trained examiners with live pattern display, structured preparation tools, notes, and completed examination records. The examiner remains responsible for deciding which responses are accepted, how observations are described, and whether a matter requires further inquiry.

During a demonstration, focus on the operational details that will remain after the first session: how templates are prepared, how recordings are reviewed, what can be documented or exported, and how the team will maintain a consistent procedure as personnel and assignments change.

Build training and supervision into the software decision

A software platform is only as dependable as the procedure around it. Qualified use requires more than learning controls and menus. Examiners need to prepare focused questions, assess recording conditions, recognize uncertainty, document observations carefully, and plan follow-up that can test rather than assume a lead.

VIPRE includes Basic Examiner Certification allocations with both AISIS and VASIS, plus recertification, online learning, live classes, and operational support. Training arrangements differ by system, so procurement teams should confirm the current package, the number of examiners to be prepared, and the support path before making a deployment decision.

Supervision matters after initial instruction. Agencies should decide who can authorize examinations, who reviews completed work, what language is appropriate in reports, and how cases are selected for quality review. Those controls help keep software in its proper role as investigative support.

Ask for evidence specific to the product and task

A demonstration can show usability. It cannot establish an accuracy rate, prove a conclusion about deception, or substitute for evidence about the exact product, version, population, and procedure under consideration. Research on a different tool is not direct validation of AISIS or VASIS, and a product's absence from a study is not proof of performance.

Ask suppliers to state plainly what their software reviews, what an output represents, and what conclusions it does not support. Then examine any available product-specific documentation for the task your team intends to perform, including the study method, comparison measure, limitations, and treatment of inconclusive results.

For every potential indicator, the operational question is what independent work follows. A lead may call for a clearer question, record review, timeline check, witness inquiry, or another source of evidence. It should never be described as software establishing that someone was truthful or deceptive.

Plan the next step with VIPRE

A useful software conversation begins with your operating environment, not a blanket promise. VIPRE can discuss AISIS and VASIS in relation to your likely assignments, examination setting, documentation needs, training plan, warranty coverage, and ongoing support requirements.

Bring the questions that matter to your investigators, supervisors, procurement staff, and agency counsel. The goal is to identify a system and deployment path that supports a careful, examiner-led process, including the circumstances in which the right professional outcome is to pause, document uncertainty, or seek independent confirmation.

Qualified agencies and trained investigative professionals can request information about available systems, included training allocations, and practical next steps for an evaluation.
