Layered Voice Analysis Technology
The Challenge
Sometimes the Words Aren’t the Whole Conversation.
Investigative professionals regularly evaluate interviews, statements and recorded conversations where additional context may help determine the next question.
Layered Voice Analysis provides another professional review layer by helping trained users examine voice-signal information.
The goal is not to replace professional judgment. It is to give qualified professionals more information to consider.
The Technology
What Is Layered Voice Analysis?
Layered Voice Analysis (LVA™), developed by Nemesysco, is proprietary acoustic signal-processing technology designed for professional analysis of voice data. Supported products process defined acoustic characteristics within the voice signal and present information for trained professional review.
02
Session information
The system presents defined voice-signal information within the context of the session or recording workflow.
03
Professional review
Qualified professionals interpret output alongside the conversation, case material, policy and investigative context.
LVA supports professional review and should not be used as a standalone conclusion about an individual.
Time-linked review

The Workflow
Professional Review, Step by Step.

Responsible Use
Professional Technology Requires Professional Judgment.
LVA provides information for trained review. Decisions remain with qualified professionals applying evidence, context, organizational policy and applicable requirements.
- LVA output is intended for trained professional review.
- Results should be considered within the complete factual context.
- Applicable product requirements vary by use case.
- Recording and data handling may be subject to law and organizational policy.
- Technology should not be the sole basis for consequential decisions about an individual.
- DDS can discuss the proposed professional workflow during consultation.
