Truth Verification with forensic digital voice analysis

---

At Precision Legal, we specialize in Voice Stress Analysis (VSA), a cutting-edge technique for credibility assessment, truth verification, and psychological stress profiling. Our expertise in this field is powered by the Digital Voice Stress Analysis (DVSA) program, the leading software used by law enforcement and government agencies for credibility assessment.

What is Digital Voice Stress Analysis (DVSA)?

DVSA represents the next generation of credibility assessment, a term that encompasses traditional lie detection methods, forensic polygraph, voice stress analysis, psychophysiology testing, and truth verification examining. Unlike traditional polygraph tests, which can yield up to 60% inconclusive results, DVSA offers conclusive findings every time, making it the most reliable tool in the industry.

Why Choose DVSA Over Traditional Methods?

• No Inconclusive Results: Unlike polygraph tests, DVSA never returns an inconclusive result, ensuring that you receive definitive answers.

• VAST (Voice Analysis Scoring Tool) & ±0 Scoring Method: DVSA is the only voice stress analysis tool that includes the Voice Analysis Scoring Tool and ±0 Scoring Method, providing a robust confirmation of the examiner’s conclusions.

• Voice Imaging Spectrograph: Our DVSA includes an optional feature for speaker identification and comparison, making it a versatile tool for various investigative needs.

• Proprietary 17 Stress Pattern Quantification Method: With a unique 17 stress pattern quantification method, DVSA sets the industry standard in stress chart interpretation. This method was validated by the United States Air Force Research Laboratory Study, confirming its 100% accuracy.

• Streaming Voice Imaging: As the subject speaks, DVSA instantly displays voice intensity, offering real-time insights during examinations.

• TARA Patterns: DVSA can display answers Time Antagonistic Response Aletheometer (TARA) patterns, providing additional layers of analysis.

• Comprehensive Charting Features: Our system provides detailed charts that display derived stress patterns, time-domain analysis, questions/answers, and much more, offering a complete view of the examination data.

Certified DVSA Examiners

Our team of examiners are DVSA Law Enforcement Certified Examiners, having completed rigorous courses certified by the American Polygraph and Voice Stress Association (APAVSA) and the International Society of Stress Analysts (ISSA). This ensures that every examination is conducted with the highest level of expertise and professionalism.

• Civil Investigations

• Employment Investigations

• Domestic and Family Matters
