WEB SURFING BY PHONE NetPhonic Communications' Web-On-Call Voice Browser allows users to phone into Web pages rather than use a PC. The system uses voice-recognition technology to dial into a Web site named by the user, and then reads back the text of the Web page. The product is marketed toward people on the go who don't have time to sit at their PCs and surf the Web, but could also be useful for the visually impaired. One drawback -- the NetPhonic software requires a high-end Sun Microsystems workstation to function. (Investor's Business Daily 12 Sep 96 A8)
