CVSA Alternative: AISIS and VASIS for Investigative Teams

Considering a CVSA alternative?

For agencies evaluating an alternative to a Computer Voice Stress Analyzer, the decision starts with the examination workflow. What does the examiner need to capture, review, document, and retain? VIPRE offers two portable systems for trained investigative professionals: AISIS combines AI-assisted stress classification with synchronized waveform, audio, and video review; VASIS provides an examiner-led voice stress analysis environment with live charting and structured examination tools.

A useful evaluation looks beyond an equipment photograph or a general claim about accuracy. Your team needs to understand the outputs, the training required to interpret them, and how the system supports follow-up. VIPRE systems provide advisory stress indicators. They do not independently determine truth or deception, and an indication must be considered alongside the interview and corroborating information.

If your agency already uses CVSA, begin by documenting the procedures and review requirements that matter to your examiners. Then assess a VIPRE demonstration against those requirements. A change of system should be evaluated as a change in equipment, training, and procedure, rather than assuming one platform reproduces another.

Compare the VIPRE deployment packages

The equipment purchase is only part of an examination program. Training allocations, warranty coverage, and access to support affect how your team introduces a system and keeps it in use. VIPRE includes certification allocations with both platforms, with different packages for AISIS and VASIS.

Ask VIPRE to confirm the current configuration, coverage terms, and training arrangements in your proposal. An agency comparing vendors should assess the whole deployment package, including the number of examiners to be trained and the operational support needed after the initial handoff.

• AISIS: four 40-hour Basic Examiner Certification allocations through the VIPRE Online University
• AISIS: three-year parts and labor warranty with service and replacement coverage
• VASIS: two 40-hour Basic Examiner Certifications through the VIPRE Online Training Center
• VASIS: one-year parts and labor warranty
• Both systems: ongoing access to VIPRE technical support and training resources

AISIS: the premium choice for connected review

AISIS is VIPRE’s premium system for teams seeking AI-assisted classification alongside synchronized examination review. The system brings response classification, waveform display, recorded audio, and video recall into one portable workstation. This lets a trained examiner revisit the timing and context of an answer while reviewing the associated stress indicators.

Choose AISIS when your agency wants VIPRE’s most comprehensive review workflow and has the budget for its expanded capabilities. AI-assisted classification and synchronized audio and video review give examiners more examination context to revisit, while keeping professional judgment central.

During structured questioning, AISIS presents color-coded waveform analysis and compiles charts for cumulative review. The examiner retains control over question preparation, accepted response segments, notes, and interpretation. Video review supplies an additional record to examine; it does not turn a gesture or expression into proof of deception.

When evaluating AISIS, ask to see the complete path from examination preparation to archived review. Review how questions are displayed, how segments are accepted or rejected, how notes are added, and how completed examinations are exported or printed. These practical steps help establish whether the platform fits your existing documentation process.

• AI-assisted classification of Stress Indicated and No Stress Indicated responses
• Synchronized waveform, audio, and video review
• Examiner control over response acceptance and examination notes
• Portable MacBook Air field configuration with camera and microphone stand

VASIS: a focused examiner-led option

VASIS gives agencies working within a tighter equipment budget a focused examiner-led option. It serves teams whose priority is a voice-based, question-driven examination workflow. It combines microphone acquisition, real-time stress-pattern display, pre-built templates, and examiner notes in a portable field unit. Interpretation remains with the trained examiner throughout collection and review.

The VASIS workflow supports pre-examination review of the question sequence, acceptance or rejection of individual voice patterns, and continuous chart compilation. Examiners can create and save templates for recurring assignments, add notes beneath patterns, and store, print, or email completed examinations for evaluation.

For a team considering a CVSA alternative, VASIS offers a separate VIPRE operating approach to evaluate on its own merits. Existing examiner experience is useful context, but the appropriate certification and operating procedures should be confirmed before deployment. Choose the platform that supports the work your team actually performs.

Prepare your evaluation around the examination record

An effective product discussion should use the same questions for every vendor. Establish what is recorded, what the examiner can review later, which exports are available, and how your team will manage access to completed examinations. Treat those answers as part of the purchasing decision, rather than details to resolve after delivery.

Do not assume that records or templates from an existing CVSA installation can be imported into VIPRE. Confirm any migration requirement explicitly. Likewise, review offline operation, retention arrangements, and compatibility against your own requirements rather than inferring them from the hardware or operating system.

• Review the question sequence and examiner controls before collection
• Examine how accepted and rejected segments are documented
• Ask for a demonstration of notes, chart review, and export options
• Confirm access controls, storage arrangements, and agency data-handling requirements
• Discuss licensing, updates, warranty terms, and support directly with the vendor

Training and transition deserve their own plan

A new platform should arrive with a clear route to qualified use. VIPRE provides Basic Examiner Certification, recertification options, online training, live classes, and operational support. Discuss the appropriate path for each examiner, including those who already hold certification on another system.

Identify who will operate the unit, who will review examination records, and who will maintain the agency’s procedures. The transition conversation should address question construction, collection conditions, interpretation, documentation, and follow-up. These responsibilities continue to matter when software offers automated setup or AI-assisted classification.

For agencies planning deployment across multiple examiners, the included certification allocations provide a concrete starting point. Confirm the course arrangements and any additional training needs with VIPRE before setting an operational schedule. Existing certification on another platform should not be treated as automatic authorization to use a different system.

Evaluate evidence for the specific product and task

A feature demonstration establishes how a system operates; it does not establish an accuracy rate. Request product-specific evaluation documentation and examine the population, task, comparison method, limitations, and definitions of the reported results. Stress classification and deception detection are different claims and require different evidence.

Research on CVSA or another voice stress product should not be presented as a direct test of AISIS or VASIS. Equally, a product’s absence from a study is not evidence of superior performance. Your agency should evaluate the documentation available for the exact system and intended application.

VIPRE’s approach places trained examiner judgment within a complete investigative process. Use stress indicators to guide responsible review and follow-up, with corroborating information and appropriate procedures. For an introduction to the field-study evidence and its scope, review the NIJ study guide before making assumptions about any vendor’s claims.

Request an AISIS or VASIS evaluation discussion

Tell VIPRE what your team needs from an alternative to CVSA: the assignments you handle, examiner experience, recording and review needs, and the number of personnel to be trained. The discussion can then focus on the appropriate system and deployment package.

Request AISIS informational-video access if synchronized audio and video review is central to your evaluation. If your priority is a focused examiner-led voice workflow, request VASIS information as well. Verified agencies can also discuss confidential reference access, subject to authentication and authorization.
