Stealth Lie Detector Measures Stress Levels Over Phone

BATM Advanced Communications is marketing a lie detector that could work over broadband and Internet phone. Executives said businessmen who deal with unseen clients could use the system. The system, manufactured by BATM's subsidiary, KishKish, monitors in real time stress levels in a speaker's voice. The system, released in December 2006 and based on voice stress analysis technology, alerts users when these levels rise, a possible indication of dishonesty.
