Do you ever wonder if your husband is really working late, if the kids really finished their homework, or if your wife is really helping a sick friend? If so, then the Voice Stress Analyzer will give you the answered you are seeking.
The voice stress analyzer can determine is the person talking is telling the truth, it analyzes the stress level changes in the voice and can work either in person or on a televised or recorded voice. This is great if you can only record their voice over the telephone or if their message is left on your answering machine.
