That sounds interesting, but I don't think it would be practical to make. I
think there is a lot of processing power required to interpret the stress in
ones voice. The software/hardware lie detectors that I have seen nust have
a way to know what is a truthfull tone of voice before being able to detect
an untruthfull tone. ie you ask the person his/her name, and a bunch of
other questions that will give a truthfull or response and let the software
know what toneal range is truthfull.
It may be easyer to use ether the change in temporature or the change in
resistance of the human skin to detect mood. These are some of the inputs a
polygraph uses along with heart rate and respiration to determine stress.
The processing could be done on the RCX with this type of system.
