Orange, California Polygraphs & Lie Detection Services

Polygraph Lie Detection
Advantages of the PSE system over traditional polygraphs:
  • PSE does NOT use painful attached wires that polygraphs must have.
  • PSE only needs a recording of the subject’s vocal responses.
  • The PSE® is NOT affected by drugs, alcohol, or any type of countermeasures.
  • PSE can be used overtly or covertly, in any language, over the phone, from any audio or video tape and entire sentences can be analyzed for lies.
  • The PSE® NEVER has “inconclusives”.

Our Voice Stress Analysis system has been independently proven to be completely reliable, effective and valid for truth verification.


In addition to our lie detection services, we also offer training in voice stress analysis and professional VSA equipment sales.

PSE Computerized Voice Stress Analysis Systems:

The PSE instrument detects, measures and graphically displays the degree of presence or absence of inaudible body tremors that are superimposed on the human voice. These tremors disappear according to the amount of stress that is present at the moment of utterance. The interview and tests are recorded by the computer or cell phone. To do a test, the PSE examiner asks the subject various questions. The PSE technology filters the vocal answers, creates patterns and displays those patterns on the screen. The PSE examiner evaluates the patterns for truth or deception.
