Voice Browser

Project/ scenario name: Custom scenario description:

Voice based Web Browser

Internet has brought about an incredible improvement in human access to knowledge and information. Voice browsers allow people to access the Web using speech synthesis, pre-recorded audio, and speech recognition. This can be supplemented by keypads and small displays. Voice may also be offered as an adjunct to conventional desktop browsers with high resolution graphical displays, providing an accessible alternative to using the keyboard or screen, for instance in automobiles where hands/eyes free operation is essential. Voice interaction can escape the physical limitations on keypads and displays as mobile devices become ever smaller. The browser will have an integrated text extraction engine that inspects the content of the page to construct a structured representation. The internal nodes of the structure represent various levels of abstraction of the content. This helps in easy and flexible navigation of the page so as to rapidly home into objects of interest. Finally, the browser is integrated to an automatic Text-To-Speech transliteration engine that outputs the selected text in the form of speech. To develop a Web Browser which will 1.

prerecorded sound for output (together with small displays when available), and a combination of keyboard and speech recognition for input. The technology will make it practical to browse the Web from any telephone using open standards for voice browsers. The Voice browsers would use speech synthesis and prerecorded material to present the contents of Web pages. A variety of aural effects can be used to give different emphasis to headings, hypertext links, list
