Secure the clarity you need with our specialized remote CVSA exams, designed for discretion and professional precision.
At California Polygraph & Investigation Services, we move beyond relationship “suspicions” to data-driven verification. Our examinations are conducted using two primary forensic technologies, depending on the client’s location and specific needs.
The CVSA is a preferred tool for remote testing. It functions by detecting micro-tremors low-frequency FM signals in the human voice that are suppressed when an individual is under the psychological stress of a lie.
For in-person examinations we utilize the gold-standard polygraph instrument. This device monitors the autonomic nervous system through three distinct channels:
Polygraph exams start at $500 and Private CVSA examinations start at $400, with final pricing based on the complexity of the case and time required for a thorough, defensible report. More involved issues, rush scheduling, or additional documentation may increase the fee, and all costs are discussed up front before booking
Confidentiality Statement: All examinations are strictly private. Results are released exclusively to the authorized client in compliance with California privacy standards.
As with all non‑polygraph technologies, California Evidence Code 351.1 applies. No method guarantees 100% accuracy.

Infidelity examinations in California are conducted under strict forensic guidelines to ensure maximum accuracy and legal defensibility.

Yes. While a traditional polygraph requires physical sensors and an in-person visit, the Computer Voice Stress Analyzer (CVSA) is specifically designed for remote use. If you are in Chico, or anywhere in Northern California, we can conduct a forensic examination over a high-fidelity phone line or encrypted digital audio link.
The CVSA is forensically reliable for private truth-seeking. It does not measure volume or tone, but rather the involuntary frequency shifts (micro-tremors) in the human voice caused by the autonomic nervous system under stress. When conducted by California Polygraph & Investigation Services, using validated issue-based questioning, provides a reliable assessment for private truthseeking, consistent with California Evidence Code 351.1.
An infidelity lie detector test in Chico utilizes issue-based questions focusing on specific physical or digital acts rather than subjective emotions. California Polygraph & Investigation Services assists clients in formulating objective questions regarding physical contact, the use of dating applications, or secret financial expenditures. This forensic approach ensures that the remote CVSA or in-person exam produces the highest levels of validity.
To prepare for a remote CVSA exam in Northern California, the examinee must be in a quiet, private location with a stable, high-fidelity phone connection. California Polygraph & Investigation Services requires that the examinee is not under the influence of substances that alter the central nervous system. A pre-test interview is conducted by the examiner to establish a physiological baseline and ensure forensic protocol compliance.
