Yet Another AI Lie Detector
 
Voice Stress Analysis

Biometrics based lie detectors are becoming more and more common by the month... and February is no exception either. CNN reports of a voice analyser, that can detect when small frequency modulations occur, usually revealing liars (Police Use Voice Stress Analysis). Artificial Intelligence is used to extract the patterns from the voice stream -- presumably generating reliable results.

I'm still not convinced any of these specific solutions are 'the holy grail'. Personally, I'd have one huge Lie'o'matic machine combining voice analysis, vocabulary choice, eye temperature, sweat measurements and expert opinions. Using probabilistic combinations of these sources of data, a very reliable result could be obtained. But then again, I guess the whole point is to psyche out the suspect and get him to confess... so the more impressive the machine, the better!
