Frequently Asked Questions (FAQ)

What is Layered Voice Analysis (LVA) and how does it differ from a polygraph? ▼
Layered Voice Analysis (LVA) uses artificial intelligence to analyze over 100 vocal biomarkers—subtle acoustic features of speech—to detect emotional states, stress, and deceptive intent. Unlike polygraph tests, which measure physical responses (heart rate, respiration, skin conductivity), LVA examines involuntary vocal characteristics derived from the limbic system. LVA is non-invasive, works on recorded audio, requires no subject cooperation, and is language-independent. It's faster, more cost-effective, and increasingly admissible in legal proceedings.
How accurate is Layered Voice Analysis (LVA)? ▼
Layered Voice Analysis (LVA) technology achieves high accuracy rates in detecting emotional states and stress indicators when properly applied. Accuracy depends on audio quality, interview duration, and the emotional content being analyzed. Our experience shows strongest results in fraud detection, deception indicators, and stress response mapping. We provide confidence scoring for each detected emotional state, ensuring transparent interpretation. Like any investigative tool, LVA is most powerful when combined with traditional investigation, forensics, and corroborating evidence.
Can Layered Voice Analysis (LVA) be used in court? ▼
Layered Voice Analysis (LVA) evidence is increasingly accepted in legal proceedings. Unlike polygraph results (which are generally inadmissible without stipulation), LVA can support testimony, strengthen witness credibility assessments, and serve as corroborating evidence. Admissibility varies by jurisdiction and context. Our reports are prepared by experienced investigators trained in expert testimony standards and can support trial or deposition. Consult with your attorney about admissibility in your specific jurisdiction.
What types of audio files can be analyzed? ▼
We accept virtually any audio format: MP3, WAV, M4A, OGG, AAC, FLAC, and more. Audio can come from interrogation recordings, phone calls, depositions, interviews, 911 calls, voicemail, and other sources. Higher quality audio (less background noise, clear voice) produces more accurate analysis. We can work with challenging audio in noisy environments, but clarity improves results. Contact us with your specific audio file and we'll assess analyzability.
Is Layered Voice Analysis (LVA) language-specific? ▼
No. Layered Voice Analysis (LVA) is language-independent. The technology analyzes vocal biomarkers—acoustic features of voice—not semantic content. Whether the subject speaks English, Spanish, Mandarin, or any other language, the emotional indicators remain identical. This is a significant advantage over transcript-based analysis or traditional interviewing, which may miss nuance due to translation or cultural differences.
Can subjects fake their way through voice analysis? ▼
Vocal biomarkers are largely involuntary—controlled by the limbic system, the same brain region that regulates emotion, stress response, and memory. While a subject might control their words, they cannot consciously control their pitch frequency, speech rate micro-variations, or other acoustic parameters that LVA measures. Deception and stress create measurable vocal changes that are difficult to fake. This is why LVA is so powerful in investigations.
How long does analysis take? ▼
Real-time analysis during live interrogations is immediate—results available within minutes of interview conclusion. Pre-recorded audio analysis typically completes within 24-48 hours depending on file length and complexity. For urgent cases, expedited analysis (24 hours or less) is available upon request. Contact us with your timeline and we'll provide a specific turnaround estimate.
How is my audio data protected and handled? ▼
We maintain strict confidentiality and security protocols consistent with FBI-level operational security. Audio files are encrypted during transmission and storage. Analysis is conducted in secure environments and files are deleted after analysis completion unless you request retention. Your case information is never shared, used for training public AI models, or disclosed without your explicit consent. All data handling complies with privacy regulations and legal standards.

Reports are prepared in formats suitable for attorney review, court presentation, or settlement discussions.
Can I use voice analysis results in my insurance claim dispute? ▼
Yes. Layered Voice Analysis (LVA) is increasingly used in insurance fraud investigations, disability claim validation, and personal injury assessments. Claimant interview analysis can reveal inflated emotional responses, inconsistencies, or deceptive intent. Results can support claim denial, negotiated settlement, or fraud prosecution. Admissibility and utility depend on jurisdiction and the specific claim type. Discuss your case with EXCALIBUR to determine how LVA can strengthen your position.
What are the limitations of Layered Voice Analysis (LVA)? ▼
Like any investigative tool, LVA has limitations: (1) Audio quality matters—background noise reduces accuracy, (2) Duration—longer interviews provide stronger analysis than brief statements, (3) Context—stress from legitimate emotional causes may mimic deception indicators, (4) Baseline—knowing the subject's normal speech patterns improves interpretation, (5) Jurisdiction—admissibility varies by court and legal framework. LVA is most powerful when combined with traditional investigation, corroborating evidence, and expert interpretation. We're transparent about limitations and provide confidence scoring for all results.
