RESEARCH PROFILE: JERK-O-METER
Profile By Anmol Madan, Research Associate
Have you ever had the experience where you call someone up and he or she doesn't seem to be paying attention to you?

The Jerk-O-Meter (or JerkoMeter) is a real-time speech feature analysis application that runs on your VOIP phone or cell phone that remedies precisely that experience. It uses speech features that measure activity and stress (and soon empathy) from your tone of voice and speaking style, to predict if you are 'being a jerk' on the phone. The phone displays appropriate messages, and can also be set up to inform the person on the other end of the line that you're extremely busy. The messages range from "Stop being a jerk!" to "Wow, you're a smooth talker," based on your performance. The application is currently designed to analyze only the user's conversation, and not the person at the other end of the line. The Jerk-O-Meter is the work of Anmol Madan, a PhD candidate at the MIT Media Laboratory, and Dr. Alex (Sandy) Pentland, a pioneer in wearable and socially aware computing.

The mathematical models for the Jerk-O-Meter were derived from several research studies at the Media Lab. These studies evaluated how a person's speaking style could reflect his or her interest in a conversation, in going out on a date, or perhaps even in buying a particular product. Our results show that a person's speaking style and 'tone of voiceĠ can predict objective outcomes (e.g. interest in a conversation, or in going out on a date) with 75-85% accuracy. For more academic information, please refer to the links at the end of this page.

The Jerk-O-Meter is just one possible implementation of the underlying technology, which has much broader applications in areas such as customized user experiences, consumer research, advertising, marketing, movies and television audiences, call centers, and various consumer and corporate applications. An important implication is that computers and cell phones may now understand people better, just as other people do. Instead of users adapting their habits to work with computers or cell phones, these devices could support us in the ways that we naturally communicate.

The current version of the Jerk-O-Meter is a research prototype, and runs in Linux on the Zaurus VOIP phone. Ron Caneel, alum of the research group, wrote part of the code to extract the activity and stress levels in real time. From a technical perspective, the Jerk-O-Meter could easily be converted into a downloadable application for a cell phone.

Jerk-O-Meter is an academic research project and is not commercially available at this time.
