Imagine this: computers are being taught to spot patterns of emotional speech - human speech that reflects deception, anger, friendliness and even flirtation.
How far we've come from "Hal."
Anne Eisenberg writing for the NYTimes, "Software That Listens For Lies," takes us to a world of promising detective research: computer linguistics. Excerpt.
"That’s because Dr. Hirschberg is teaching computers how to spot deception — programming them to parse people’s speech for patterns that gauge whether they are being honest.
For this sort of lie detection, there’s no need to strap anyone into a machine. The person’s speech provides all the cues — loudness, changes in pitch, pauses between words, ums and ahs, nervous laughs and dozens of other tiny signs that can suggest a lie.
Dr. Hirschberg is not the only researcher using algorithms to trawl our utterances for evidence of our inner lives. A small band of linguists, engineers and computer scientists, among others, are busy training computers to recognize hallmarks of what they call emotional speech — talk that reflects deception, anger, friendliness and even flirtation."
While it is unlikely that the research or the software will be used in courts of law, the goal is to plumb the depths of human speech for the clues it gives in analyzing speech.
“The scientific goal is to understand how our emotions are reflected in our speech,” Dr. Jurafsky said. “The engineering goal is to build better systems that understand these emotions.”
The programs that these researchers are developing aren’t likely to be used as evidence in a court of law. After all, even the use of polygraphs is highly contentious. But the new programs are already doing better than people at some kinds of mind-reading."
Admittedly, the computers are still struggling with the finer signs of emotion - a not too different situation from us homo narrans. Yet, what we do have that the computers lack is access to facial expression, body language, and experience to help us discover meaning in language.
TIP: One place litigators can practice focused listening is in focus group research. Stop all else and listen to what is being said about the legal stories you are telling the members of the community.
TIP: Pay attention to three things: (1) the facts the participants use to discuss the legal stories, (2) the emotion they use to express their thoughts, and (3) the intention behind the words. You might hear energy, boredom, fatigue, doubt, confusion, or enthusiasm. The way words are spoken informs the attorney about underlying messages.
TIP: Take careful note of the analogies the participants use to bring their life experiences and world views closer to (or further away) from your client's.
TIP: If they are not finding the universal story in your client's particular life experience that is a most important clue to inform you how you could lose this case.
TIP: Rework the legal story from a place of "How can we lose?" based on what you heard them say to more closely align the legal proof of your story with this "community proof" necessary to persuade the decision-maker.
