2 LVA 6.50 Investigation Focus Tool
A professional truth verification system Designed to assist any investigative procedure by analyzing the subject’s reactions reflected in his voice – Language independent! Flags and categorize unexpected emotional reactions in the course of the conversation/investigation and directs the investigator to concentrate on the relevant (problematic) issues in the subject’s story Designed for professional investigators (governments security organizations, law enforcement agencies, security officers and investigators) following a one week training.

3 LVA 6.50 is useful for: Investigation rooms Undercover analysis
Over the phone veracity assessment Operatives (Humint) data collection “Cold cases” analysis Psychological profile assembly High profile human resources recruitment Intelligence acquired data analysis Open sources data evaluation

4 LVA 6.50 Investigation Focus Tool
The LVA 6.50 system has three operation modes: Online Mode: real-time analysis of face-to-face or over-the-phone conversations . Offline Mode: in-depth analysis of pre-recorded material. Investigation Mode: Analyze Yes/No questionnaires. Uses the same techniques and questionnaires as the standard polygraph (not explained in this slide show)

5 Core parameters LVA 6.50 technology can detect and differentiate between various emotional states: (Partial list) General Stress (survival instinct) Emotional Stress (Excitement and anger) Cognitive Stress (certainty\uncertainty level) Mental effort (creative mind, imagination) Embarrassment and high concentration states Hesitation and anticipation

6 Real-time analysis of open conversations
ONLINE MODE Real-time analysis of open conversations

7 Online Mode Provides veracity and emotional analysis during open conversation using a microphone or over the phone Highlights problematic issues during the conversation with real-time textual messages ("Truth", “Excitement”, “High Risk", etc.) Use interactive graph display for analysis review Allows the investigator to identify the relevant issues in real-time and focus on them, saving precious investigation time, resources and energy.

8 Online Mode - process Step 1 : Creating the subject’s voice baseline: An automatic calibrating process is performed for few seconds (on the subject’s first few sentences). Step 2: Conducting the interview: The system analyzes every 1-2 seconds of the subject’s voice Step 3: Use the visual feedback: indications include simple textual feedbacks such as "Truth", “High Risk", "Inaccuracy/ Med. Risk“, “Subject Not Sure”, "High Stress“, etc.

9 In-depth analysis of pre-recorded material
OFFLINE MODE In-depth analysis of pre-recorded material

10 Offline Mode In-depth analysis of pre-recorded files (imported from other systems or recorded with LVA Online mode) Higher accuracy and more detailed analysis: Uses more parameters for higher accuracy Allows manual removal of noise and improvement of the sound quality Provides easy to read textual and graphic feedback Manages the previously analyzed test files in a simple database set for easy retrieval

11 Offline Mode - process Step 1 : Creating a “Test case” The operator defines a new test case and associate the wave file to be analyzed with the subject/s details Step 2: Segmentation process LVA offline segments every 1-2 seconds of the file’s voices into analysis units. The operator reviews the segmented data to clean out noises and irrelevant voices Step 3: Analysis review The operator reviews the analysis results and draws conclusions

12 LVA Advantages

13 LVA 6.50 and some more advantages…
The most user friendly and flexible system of its kind Highly accurate and difficult to manipulate The suspect does not have to know or give consent to the test (where applicable by law) Requires only one week of training to operate (level 1 operators)
