Thought this information would be of interest to the group. Jon > >Voice Browser Packages Will Offer Hand-Off Access to Web Sites >From: PC Week - November 9, 1998 - page 36 >By: Herb Bethoney > >Voice-enabled browsers offer the potential to deliver Internet information to >a much broader audience. By offering speech access to Web pages, voice >browsers will provide hands-free access to online information while driving a >car, for example. > >Web pages designed for viewing on a computer screen deliver a wealth of >information, but attempts to simply convert a Web page into speech - via a >text-to-speech application, for example - are laden with pitfalls. Elements >commonly found in electronic commerce Web sites, such as forms, frames, >diagrams and image maps, have no direct translation to speech and are not >easily navigated via the telephone. > >A voice browser accessible from a telephone must let users access Web links >and fill out form fields. Although IVR (interactive voice response) systems >have been around a long time, their menu-driven architecture doesn't lend >itself to the nonlinear aspects of surfing the Web. > >There are generally two approaches to bringing speech access to the Internet. >One approach is to extend HTML using style sheets. ACSS (Aural Cascading >Style Sheets), part of the World Wide Web Consortium's recommendation for the >CSS 2 specification, allows a document to be displayed aurally as well as >visually without requiring a separate Web page for each mode. ACSS is a >specification for reading Web pages to a user but doesn't provide a way for >developers to allow users to input speech. > >The other approach is to create a specific markup language for rendering >speech input as well as output on the Internet. This is the approach Motorola >Inc. has taken with its VoxML specification. > >But Motorola isn't the only player in the voice browser game. IBM has been >working with visually impaired computer users for many years to design screen >readers and provide accessibility to information technology. The result is >IBM Home Page Reader, a voice browser designed by Chieko Asakawa, a blind >researcher in IBM's Tokyo Research Labs. Home Page Reader, which is suitable >for voice input as well as output, was released in Japan in October 1997. IBM >Special Needs Systems, in Austin, Texas, is adapting it for North American >users and is adding support for HTML 4.0. > >Lucent Technologies Inc., of Murray Hill, NJ, is developing PhoneBrowser, a >speech recognition product for Internet service providers. PhoneBrowser is a >programmable platform that allows Web page authors to build IVR systems >without using expensive IVR equipment. > >PhoneBrowser reads Web pages to a caller via text-to-speech conversion. Users >control PhoneBrowser's voice browser by speaking over what the browser is >"saying," thus allowing a user to go to a specific point on a Web page >without having to wade through seemingly endless options. > >Siemens Corporate Research Inc.'s Liaison voice browser research effort is >aimed at providing drivers with access to Web-based information. Liaison is >an eyes-free and, for the most part, hands-free voice browser. Siemens, of >Princeton, NJ, is attempting to make listening to the Web like listening to >the radio, allowing drivers to make more productive use of their commuting >time. In an automobile, safety is the first concern, so Liaison uses a simple >voice navigation framework that demands minimal interaction. > >On the academic front, the Massachusetts Institute of Technology's Laboratory >for Computer Science has developed a speech system, called Jupiter, that >provides conversational access to weather information for 500-plus cities via >a standard telephone. > Jon Gunderson, Ph.D., ATP Coordinator of Assistive Communication and Information Technology Division of Rehabilitation - Education Services University of Illinois at Urbana/Champaign 1207 S.
