When Mike McCue founded Tellme in 1999 its initial product was a voice-driven information service what might be termed a ”voice portal.” Today the company’s voice-recognition systems power directory assistance services from AT&T Verizon and Cingular along with automated 800-number customer help lines at companies like Merrill Lynch and Federal Express. But McCue still harbors dreams of a broader voice-driven web one which will provide consumers with new ways of using the phone to interact with the universe of information. He discussed this vision and others during a recent interview with Knowledge at Wharton in Tellme’s Mountain View Calif. offices.
