New software aims to keep customers honest

A controversial program that can identify when someone is lying is being adapted for use by the call center industry.

Officials said iVocal is "not a lie detector but a risk manager," designed to assist operators during telephone dealings with customers.

Made by Israel-based Trustech, the program listens for stress and other characteristics in a person's vocal patterns to determine the likelihood that a person is exaggerating, telling half-truths or outright lies.
