D. A Computer Program Let's You Do The Talking

Narrator: This is Science Today. Decades ago, Dr. Louis Gottschalk, a neuroscientist at the University of California, Irvine co-developed the Gottschalk-Gleser scale which accurately measures various emotional and cognitive brain disorders. It works by analyzing and scoring a subject's speech sample against a set of norms.

Gottschalk: The problem with these scales was they're very time consuming. Somebody has to learn what gets scored in certain ways and the computer came along and I was swept up by the computer and decided wouldn't it be great if we could develop a computerized version of the scoring?

Narrator: Now, some fifteen years later, such a program has been developed.

Gottschalk: The computer program can be improved. The software has a dictionary. It knows every idiom or slang term that communicates something about the scales the we're involved in. It has an interaction so you can bring it up to date.

Narrator: For Science Today, I'm Larissa Branin.
