When trust is broken in a relationship or a professional partnership, the uncertainty can be more paralyzing than the truth itself.

How Our Forensic Truth Verification Process Works

Understanding the sequence of a truth verification exam helps reduce anxiety and ensures the most reliable results. At California Lie Detection, we follow a structured, multi-phase protocol designed to maintain professional objectivity while providing an empathetic environment for those facing difficult personal or legal situations.

Our CVSA (Computer Voice Stress Analyzer) process is framed as a voice-based risk assessment tool, providing an additional layer of forensic analysis for private truth verification.

Phase 1: The Briefing & Pre-Test Interview

Before any testing begins, the examiner reviews the specific circumstances of your case. This is followed by a pre-test interview where we discuss the issue at hand. This step ensures that the subject understands the process and that all questions are clear and unambiguous.

Phase 2: Formulating the Questions

Examinations typically contain between 9 and 31 questions. These are categorized into:

  • Irrelevant Questions: Neutral questions used to establish a baseline.
  • Relevant Questions: The core questions regarding the specific issue (e.g., infidelity or theft).
  • Control Questions: Used to gauge the subject’s physiological reaction to the pressure of the interview.

Phase 3: Technical Analysis & Interpretation

During the exam, the CVSA instrument captures the human voice. Our software analyzes the frequency patterns for micro-tremors , involuntary physiological changes that occur under the stress of deception. As a forensically reliable tool for private use, the charts are then interpreted by our lead examiner to identify specific stress patterns associated with your relevant questions.

Phase 4: Results and Clarification

If stress patterns are observed, the subject is given a professional opportunity to clarify their responses. This “post-test” phase is vital for context. Once the analysis is complete, a conclusion is reached. If the relevant questions produce a “No Stress” chart, the subject is considered “cleared” by the CVSA procedure.

Disclaimer: As with all non‑polygraph technologies, California Evidence Code 351.1 applies. No method guarantees 100% accuracy. Our services are designed as a validated tool for private truth verification and risk assessment.

Pricing, Locations, and Remote Testing Options

Accessibility and transparency are core to our mission at California Lie Detection. We understand that when you are seeking the truth, you need clear information regarding logistics and investment. We focus our physical operations on primary Northern California hubs to ensure consistent, professional service without the confusion of redundant county-wide listings.

Private Exams process

We offer two primary forensic paths based on your specific needs and location:

  • In-Person Polygraph: Conducted at our primary offices, this is the gold standard for high-stakes personal and legal truth verification.
  • Remote CVSA: This voice-based risk assessment is conducted via a secure, high-fidelity audio link, making it the most flexible and cost-effective option for clients outside our immediate physical reach.

Our Northern California Service Areas

To maintain the highest level of examiner expertise, we anchor our physical testing in three key regions. If you are located in the surrounding areas, these are your primary destinations for in-person testing:

  • Chico / Butte County: Our central hub for North Valley clients.
  • Vallejo / Solano County: Serving the Greater Bay Area and I-80 corridor.
  • Redding / Shasta County: Serving the northernmost reaches of the state.
  • Yuba City: Available for scheduled appointments and our primary focus for remote CVSA services.

Remote vs. In-Person: Which is Right for You?

While the in-person polygraph is often preferred for legal matters, our Remote CVSA is increasingly popular for infidelity and relationship betrayal cases. It allows the subject to remain in a familiar environment, which can often lead to a more fluid interview process while still providing a forensically reliable result for private use.

Confidentiality and Legal Standing in California

When dealing with sensitive matters like relationship betrayal or private disputes, privacy is just as important as the truth itself. At California Lie Detection, we maintain a strict firewall around your data and results. Our examinations are conducted with the highest level of professional discretion, ensuring that the results are released only to the authorized client.

Private Use vs. Court Admissibility

It is essential for clients in Chico, Redding, and Vallejo to understand how these results can be used. While our methods are forensically reliable for private truth verification, the state of California has specific rules regarding their use in a courtroom.

  • California Evidence Code 351.1: This code generally prohibits the admission of polygraph (and by extension, other lie detection) results in criminal proceedings unless all parties agree to it.
  • Private Utility: Most of our clients use these services for “peace of mind,” internal corporate resolutions, or as a catalyst for honesty in therapy and relationship counseling.
  • Voluntary Participation: All examinations are voluntary. We provide a neutral, non-confrontational environment to help the truth surface naturally.

Legal Disclaimer: As with all non‑polygraph technologies, California Evidence Code 351.1 applies. No method guarantees 100% accuracy. These tools are intended to assist in private decision-making and risk assessment.

Frequently Asked Questions

What kind of questions can be asked during the exam?

Questions must be clear, direct, and require a Yes or No answer. We avoid “why” or “how” questions during the technical phase. For example, instead of “Why did you go there?”, we ask, “Did you go to that location on Friday night?” We work with you during the pre-test phase to ensure the questions target the specific heart of the matter.

How long does a typical session take?

A standard session in our Chico or Vallejo offices takes between 90 and 120 minutes. This includes the pre-test interview, the data collection phases, and the final results discussion. Remote CVSA sessions follow a similar timeline.

Is the CVSA or Polygraph 100% accurate?

No method of lie detection is 100% accurate. Our technologies are validated for private use and are highly effective at identifying physiological stress associated with deception. We frame our results as a voice-based or physiological risk assessment to help you make informed decisions.

Can I do the test over the phone?

We offer Remote CVSA services via a secure, high-fidelity audio link. This is not a standard “phone call” but a controlled forensic interview conducted over a platform that ensures audio clarity for accurate stress pattern analysis. This is a popular option for clients in Yuba City and Santa Rosa.

Take the first step toward clarity. 

Whether you are in Butte, Shasta, or Solano County, our expert examiners are ready to provide the professional analysis you deserve.
