As part of Verizon's "Droid Does" campaign, in Times Square, NY City, Google Search by voice is powering Times Square's largest combined displays ‘Reuters Sign and NASDAQ sign’. Anyone can call 888-376-4336 and say name of a business or a location — they want to search for…then, the query and local search results from Google’ll appear on one of the two electronic billboards from 12:30-2:00pm or 6:30-8:00pm on any day. On Black Friday, Times Square's gigantic interactive search-by-voice demo will be running for 20 hours straight. So if you're in the area, give the demo a try. And for those of you that aren't in Manhattan, can still watch the action via webcam. Here’s how the system works: “A caller's voice is sent through the phone system, directly into a small farm of real Droids running voice search that are connected to the big outdoor electronic displays! R/GA developers made use of the Android voice recognition API just like any Android developer can.”
