The Jerk-o-meter

Researchers at the Massachusetts Institute of Technology are developing software for cell phones that would analyze speech patterns and voice tones to rate people — on a scale of 0 to 100 percent — on how engaged they are in a conversation.
Anmol Madan, who led the project while he pursued a master's degree at MIT, sees the Jerk-O-Meter as a tool for improving relationships, not ending them. Or it might assist telephone sales and marketing efforts.
