"It took a year to build and program. I worked about 10 or ts hours a week in my spare time. I guess it took about 500 hours all together." The computer speaks by sounding out words. Gray types a code for each sound into the machine. and the computer pieces the sounds together to produce words and sentences. Gray, of Regina Street, Waterloo. is an 18-year-old Grade 13 student at Waterloo Collegiate Institute. He built the computer himself and equipped it with special circuitry to mimic the human voice. "It can speak 300 words, but all of them are in a flat monotone. with a sort-of eastern accent." he said with a grin. Gray's talking computer was one of the highlights of the more than 200 exhibits at the fair, which was held at the Donn Campus of Conestoga College from Wednesday to Satur- day. Jan Gray's favorite hobby is talking to machines. And the machines talk back, as he cheerfully demonstrated to visitors at the ninth annual Waterloo-Wellington Science and Engineering Fair.

Walrr loo “I want to program computers to mimic thought processes." However. this will be very difficult. since "our brain is like millions of little computers that are all working at once," he said. But can the machines actually think? “I don't see why they can't make a computer that copies everything a brain can do. " it copies the work of the brain. is it thinking?" Even Gray isn't sure about that one. One of his projects was to produce a program to control a pig barn. It opens valves to feed the pigs and automatically keeps track of their weight. ' And what does Gray plan to do when he finishes high school? Take computer science at the University of Waterloo. of course. He is especially interested in the intelligence level of the machines. Gray spent about $500 for the parts to build his computer. He earned the money by working - with computers. of course. Gray works for a Kitchener firm, Limnoterra Environmental Biologists. programming and building computers. The hardest part about building a computer is getting the timing right, he said. "Each operation (by the computer) is done in a millionth of a second and the timing must be right within 50 billionth of a second." computer. Gray learned the basic electronics needed to assemble his computer in high school, but the rest of his information came from friends at the university, who Rave him technical manuals and instructions. Gray dubbed his talking computer the Gray 1. "The name is a pun, since the world's fastest computer is named the Cray l." he ex- plained, so"
