Since the service launched in 2007, Google has been quietly bettering its various voice-driven systems. When Google launched its own free 4-1-1 service, the company said it planned to use the voice samples captured by the phone system to improve its voice recognition. With the imminent closing of GOOG-411, users calling from landlines have been scrambling to find other free alternatives. While the old standby of 1-800-FREE-411 remains in mediocre homeostasis, and Microsoft's relatively new BING-411 service is sure to pick up when google drops the ball.
