Awhile back we were discussing voice-stress analysis; just got this item on the subject; he said it's okay to post it.

MR. BELL:
I FOUND YOUR QUERY ABOUT VOICE STRESS ANALYSIS ON THE INTERNET, AND I TOO, HAVE FOUND A DEARTH OF INFORMATION THERE - UNTIL NOW.
I'M PLEASED TO REPORT THAT VOICE STRESS ANALYSIS (VSA) IS ALIVE AND WELL. IT HAS BEEN QUIETLY PERFORMING IN THE SHADOW OF THE POLYGRAPH FOR MANY YEARS. NOW, HOWEVER, IT IS COMING INTO ITS AND IS USED IN MANY STATES TO AID IN CRIMINAL INVESTIGATIONS AND OTHER APPLICATIONS.
...
THE DIOGENES GROUP, INC., OF WHICH I AM PRESIDENT, HAS DEVELOPED A TOTALLY DIGITAL APPROACH TO VSA, AND BEGAN DELIVERING SYSTEMS TO LAW ENFORCEMENT AGENCIES IN DECEMBER, 1996. THE PREMIER DIOGENES VSA PRODUCT IS REDUCED TO THE SIZE OF A NOTEBOOK COMPUTER, BUT PRODUCES REALTIME PROCESSING FOR SOFTCOPY DISPLAY, AND HARDCOPY PRINTING WITHIN SECONDS.
YOU MAY BE FAMILIAR WITH THE PREVIOUS STATE-OF-THE-ART, WHICH WAS A RELATIVELY LARGE ANALOG MACHINE, USING A SINGLE CHANNEL AND PRINTING OUT THAT DATA ON A ROLL OF THERMAL PAPER. THOSE DAYS ARE GONE FOREVER.
IF YOU WOULD LIKE MORE INFORMATION ON THE DIOGENES GROUP AND ITS PRODUCTS, PLEASE USE THIS CHANNEL TO SEND ME YOUR MAILING ADDRESS, PHONE NUMBER, AND FAX NUMBER.
THANKS FOR YOUR INTEREST IN VOICE STRESS ANALYSIS. ... Check the Readers Guide for the last couple of years. I don't have my Popular Electronics collection handy, but not too long ago they put out the

This allowed the unit to be much smaller and simpler, sacrificing some of the accuracy for a reasonable price (PC board, parts and case available for, I think, less than $100). The whole unit fit in a case about the size of a transistor radio and used a couple of bar graph displays (LED) for output. The whole operating theory is regulary printed with the schematics, and a parts list and foil diagrams are included for those who want to make the project from scratch. While your at it, look up the subliminal mixer from about 1992, I made one of these and only prevented from using it by the lack of a decent power supply. The single frequency mentioned above is further explained in the text. The local library can get a copy of either of these issues, or any others that catch your interest, for you if you ask really nicely.
